Research in the Age of the Context MachineCarsten Keßler
This document discusses research challenges in context-aware systems as context becomes more integrated into technology. It outlines the evolution from early location-based systems to modern context-aware systems that consider location as well as other contextual factors like weather, points of interest, connected devices, social relationships, schedules and interests. Three key research challenges are presented: 1) effective representation and integration of different types of context data, 2) determining what context is relevant for a given task and how this may differ between users, and 3) ensuring user privacy and control over what context data is shared while still enabling useful services.

Applications of RS and GIS in Urban Planning by Rakshith m murthys0l0m0n7
This document discusses the application of remote sensing (RS) and geographical information systems (GIS) in urban planning. It explains that RS allows for the collection of spatial, spectral and temporal data about areas in an accurate and cost-effective manner, while GIS stores and analyzes geographic data in layers. The document then provides several examples of how RS and GIS have been used in urban planning, including analyzing urban sprawl in Bengaluru, mapping land use changes in Mysuru over time, assessing water demand and supply in Nairobi, and monitoring archaeological sites for encroachment using satellite imagery. It concludes that RS and GIS are necessary technologies for urban planning authorities to efficiently respond to issues faced by rapidly urbanizing
A multi-scale Urban Analysis Using Remote Sensing and GISWaqas Tariq
Urban planning was very much a design and engineering exercise with the state as a single stake holder. Mega cities with millions of population, has undergone a series of physical as well as socio-economic changes over the last 60 years. In India, Hyderabad experienced a high rate of urbanization facing structural, environmental, social and economic problems. To provide a holistic perspective on the urban characteristics, an interdisciplinary research approach is used. GISGeographic Information System and Remote Sensing provide the advance techniques and methods for studying urban land development and assist urban planning.
Open Space and East Grand Rapids Property Values (2)Tyler Lancaster
This study analyzed the effect of open spaces on surrounding property values in East Grand Rapids, Michigan using GIS analysis. The results showed a moderate relationship between proximity to parks and lakes and higher property values, while the relationship between proximity to trails and property values was more random. A hedonic model could potentially explain more of the external factors influencing property values. Future research could examine the relationships between open spaces and property values in other cities and include additional externalities.
This document describes the process of dasymetric mapping to more accurately distribute population data spatially. It provides an example of mapping Wisconsin's population based on census tracts, which often do not accurately reflect population density variations within the tracts. Land cover data is used as the controlling variable to redistribute populations from census tracts to zones estimated to have different population densities based on land cover type, through a regression analysis. While an improvement over simple census tract mapping, issues include the land cover data not being a perfect proxy for population distribution.

State of the Map Asia (SotM-Asia) is the annual regional conference of OpenStreetMap (OSM) organized by OSM communities in Asia. First SotM-Asia was organized in Jakarta, Indonesia in 2015, and the second was organized in Manila, Philippines in 2016. This year’s conference, third in the series, was organized in Kathmandu, Nepal on September 23 – 24, 2017 at Park Village Resort, Budhanilkantha, Kathmandu, Nepal.
We brought nearly 200 Open Mapping enthusiasts from Asia and beyond to this year’s SotM-Asia. The event provided an opportunity to share knowledge and experience among mappers; expand their network; and generate ideas to expand map coverage and effective use of OSM data in Asian continent. We chose ‘from creation to use of OSM data’ as the theme of this year’s conference, emphasizing on the effective use of OSM data. We also brought together a government panel from four different countries in this year’s SotM-Asia. We believe this event will deepen the bond and enhance collaboration among OSM communities across Asia.

GIS technology is useful for urban planning by helping to analyze urban growth and identify suitable sites for development based on factors like accessibility, topography, land use, and water resources. GIS can be used to create resource inventories by integrating remote sensing data, analyze existing urban situations through overlay analysis, model and project future population changes, develop planning options through land suitability maps and spatial optimization, help select options through multi-criteria analysis, and aid in plan implementation through environmental impact assessments. In summary, GIS is crucial for sustainable urban development and economic growth by allowing rapid updating of data layers and assessment of land use changes over time to inform better urban planning.
GIS for the Masses: Volunteered Geographic InformationCarsten Keßler
Volunteered geographic information (VGI) refers to geographic data created, assembled, and disseminated by individuals voluntarily. Examples of VGI projects include OpenStreetMap, where over 1.4 million registered users have mapped over 2 billion nodes and 200 million ways. OpenStreetMap is a major VGI project that started in 2004 and now has comprehensive mapping data for the entire planet. Research on VGI focuses on data quality assessment, understanding contributor motivations, and integrating VGI into authoritative geographic systems.
GIS allows users to store, manipulate, and analyze spatial data represented in layers. It underpins data with vector locations that can then be plotted to show information geographically. Users can ask questions of spatially-related data, search for patterns and distributions, and investigate relationships between different data sets. How data is displayed through options like color, size, and classification can influence the patterns seen. It is important to consider who created data sets and how current they are.

Geo-Information Visualizations of Linked Data. Linked Data provides an ever-growing source of geographically referenced data for application development. In this paper, we analyse the workflow behind the development of such an application. Using two examples based on worldwide development aid and refugee data, we discuss the steps from locating data for use and data integration, up to the actual visualization in a web-based application. At each step, we discuss the skill set required for completion and point to potential challenges. This includes RDF, SPARQL, HTTP requests, HTML, and JavaScript. We conclude the paper by putting our case study in the context of GIScience curriculum development.
The document discusses the emerging trends in geographic information systems (GIS) for real estate development. It notes that foreign investment in real estate has increased demand for land information but this information is dispersed across different government departments without standardization. GIS can help integrate this information on land ownership status, infrastructure access, zoning, and utilities. It also discusses how GIS needs are shifting from 2D parcel maps to 3D/4D models with accurate boundaries and property layers to better support complex urban planning activities. Regularly updating integrated regional/national maps will be important to facilitate real estate and land market activities globally.

Geography and Public Health: Using Technology to Strengthen ProgramsMEASURE Evaluation
The document discusses how technology and geography can strengthen public health programs. It describes how John Snow's map of the Broad Street pump helped identify the source of a cholera outbreak. Geographic information systems (GIS) have expanded mapping applications for health and made them more accessible. Current tools like STATCompiler allow linking data to geographic locations. New tools aim to improve functionality for interactive web mapping and sharing maps. Technology has changed mapping by enabling non-experts to create maps more easily and share them online or via mobile devices. However, reliance on organized data and choosing the right scale remains important.

The empirical analysis in the thesis examines the Boston metropolitan region to identify relationships between live-work-play mixes and various
Configurational Economies: The Value of Accessibility in Urban Development drboon
The document discusses the relationship between spatial configuration, accessibility, and economic value in urban development.
It proposes that (1) spatial configuration determines patterns of movement through urban spaces, (2) patterns of movement generate land use patterns by attracting certain uses to more accessible areas, and (3) this "movement economy" is capitalized into property values. Accessibility, as measured by Space Syntax, can therefore help determine property prices.
The paper reviews theories linking urban form, land rents, and the location of different land uses. It argues accessibility has both spatial and economic dimensions - as a spatial parameter influencing diversity and urbanity, and an economic parameter reflected in property prices near more accessible areas. Understanding these config

This document summarizes a study that analyzed the spatial patterns of land use change in Bangalore, India from 1973 to 2010 using remote sensing data and landscape metrics. The region was divided into zones radiating from the city center, and landscape metrics were computed for each zone to understand spatial and temporal patterns of urbanization. Principal component analysis and canonical correlation analysis were used to prioritize important metrics. The analysis found 28.47% growth in Bangalore's urban area over this period, with compact growth in the center and sprawl in peri-urban regions. Landscape metrics revealed how the spatial structure of urbanization changed over time.

This document analyzes spatial patterns of urbanization in Bangalore, India from 1973 to 2010 using remote sensing data and landscape metrics. The study area was divided into zones radiating from the city center, with each zone further divided into concentric circles. Landscape metrics were computed for each circle and zone to understand local spatial dynamics. The analysis found compact urban growth near the center and more dispersed development in peri-urban areas. Shannon's entropy was used to measure urban sprawl, showing more fragmented growth farther from the center. Between 1973 and 2010, urban area increased from 1.87% to 28.47% of the total, while vegetation decreased from 62.38% to 36.48%, revealing the impact of rapid urban

This document provides an overview of agent-based modeling and geographic information systems (GIS). It discusses why urban systems are complex and why individual-based modeling is useful for understanding urban dynamics. Agent-based models simulate individual agent behaviors and measure how system properties emerge over time from these interactions. GIS represents real-world phenomena spatially through layers of raster (grid) or vector (points, lines, polygons) data. Integrating GIS and agent-based modeling allows modeling agents located in actual spaces and discovering new patterns through their interactions over space and time. The document reviews example applications and modeling toolkits for building spatial agent-based models.

An urban transportation system is crucial to a city's overall development. Having an effective transportation system is crucial to raising the standard of living in urban areas. Effective utilization is crucial due to the transportation network's enormous development costs. Reaching optimal utilization necessitates appropriate connectivity and orientation. Urbanization has led to massive population growth and related activities in many developing countries. Inadequate transportation options and associated travel problems are the result of this. Therefore, developing ways to increase the transport network's efficiency requires a parameter-based evaluation of the network. It involves determining the variables that affect travel as well as the instruments and methods for defining urban features including the land use and transportation system. Research gaps are determined using the literature review as a guide. By recognizing the influences of land use on networks, networks on land use, networks on travel, and once again, networks on travel, the current study offers a paradigm for developing urban transportation networks. Information about land use, zonal boundaries, and the road network was gathered from the appropriate organizations. GIS was used to convert these to digital format.

Taufiq dan Kombaitan - 2019 - Urban Area Entities in Affecting Regional Devel...EmTaufiq1
This document discusses urban area entities and their role in affecting regional development, using the Mebidangro urban area in Indonesia as a case study. It finds that Mebidangro influences regional development through four main entities: 1) Reducing income disparity, 2) Being a central location for production and services, 3) Facilitating urbanization and labor/knowledge mobility, and 4) Enabling regional and international cooperation. While cities were once seen as hierarchical, the globalization of industries and innovation has led to more open and networked urban cooperation beyond administrative boundaries.
The document describes a project that developed an interactive online profiler tool to analyze and compare suburban town centres in London. The profiler compiles socio-economic, spatial, and transportation data into interactive maps to help users visualize relationships between the built environment, economic activity, and commuting patterns in different suburban town centres. It was designed to test hypotheses about what contributes to the economic success of suburban areas and inform policy around suburban town centre design.
Studying perceptions of urban space and neighbourhood with mobloggingDania Abdel-aziz
This document describes a study that used a novel methodology called "moblogging" to examine people's perceptions of their neighborhoods. Moblogging involves using a mobile phone to record media like photos, audio notes, and location data during self-guided tours of one's neighborhood. The study collected qualitative data from 15 participants through moblogging activities and workshops. The results highlighted how people use public and private landmarks, differences in spatial knowledge between urban and rural dwellers, and individual strategies for orientation. The findings suggest guidelines for designing personalized spatial profiles in technologies.
Similar to 1A_4_GIS enhances collaboration: using the line to draw disciplines together (20)
This document investigates how changing the location of polling stations can affect voter turnout. It uses a case study of Brent, UK to build binomial machine learning models predicting turnout based on factors like voter density and distance to polling stations. The models show turnout increases by 2-4% if 50-100% of voters are within 500m (European election) or 600m (local election) of stations. Ward-level analyses found relocating stations could increase turnout probabilities by up to 5% depending on election and location. The study supports how geographical accessibility factors influence turnout, especially in lower-salience elections.
This document discusses a method for identifying the most salient mountains in images for annotation purposes. It involves analyzing EXIF metadata, computing apparent and prominence salience scores, and using viewshed analysis on digital elevation models. The goal is to annotate images with the most visually prominent mountains, not necessarily the highest summits. The method was tested on mountainous regions in Switzerland with preliminary results showing identification of mountains like the Matterhorn and Monte Cervino. Further work could expand evaluations and consider additional factors like distance, landform shape, and semantic salience from crowdsourced data.
7B_2_Topological consistent generalization of openstreetmapGISRUK conference
This document discusses techniques for topologically consistent generalization of OpenStreetMap data for use in location-based services. It examines methods for determining if a simplified map preserves topological properties like planarity without false positives or negatives. The techniques are evaluated based on constraints for different types of topology and simplification. Results show the methods can simplify OpenStreetMap data while maintaining important invariants like shape and size for use on location-based devices. Future work includes simplifying all linear features and progressively transmitting map data.
7A_4_Gps data collection setting for pedestrian activity modellingGISRUK conference
This document discusses collecting GPS data for modeling pedestrian activity. It outlines the background, why high frequency data collection is needed for pedestrians, how a test was conducted, analysis of the test results, and conclusions. The test collected walking data every 1 second and then thinned the data to varying rates. The analysis found that positional accuracy was around 15-20 meters, length calculation was most accurate at 20 seconds, speed calculation worked best at 30-60 seconds, and start and end points were most accurate between 10-20 seconds. In conclusion, an epoch rate of 20-30 seconds was determined to be most appropriate for pedestrian route modeling.

This document summarizes a PhD thesis that uses GIS and spatial modeling to analyze the sustainability of aggregate mineral supply in the UK. The research aims to:
1) Build a GIS model to represent consumption, supply, and transport networks of aggregates.
2) Develop a spatial interaction model to simulate aggregate flows via different transport methods.
3) Evaluate environmental and social impacts like carbon footprint to compare policy scenarios for aggregate delivery.
5A_1_Land evaluation techniques comparing fuzzy ahp with ideal point methodsGISRUK conference
This document compares the Fuzzy Analytic Hierarchy Process (AHP) and Ideal Point methods for land suitability evaluation. Both methods were used to evaluate land characteristics for wheat production, resulting in land suitability maps. The maps were compared and found to have good agreement, with most locations deemed moderately suitable by both methods and few areas found highly or less suitable. While the Ideal Point method showed some bias toward ideal values, both techniques effectively incorporated local knowledge on land characteristics and their relative importance for wheat.
4B_3_Automatically generating keywods for georeferenced imagedGISRUK conference
This document discusses automatically generating geographically relevant keywords to describe image content. It presents a process that takes an image's coordinates and extracts potential visible areas from spatial data. Candidate keywords are generated by mapping visible spatial features to concepts and filtering/ranking them based on spatial extent, descriptiveness, and web search popularity. Initial results found ~40% of generated keywords were good descriptors for test images. Lessons learned include directional accuracy issues and benefits/challenges of using open data sources like OpenStreetMap for urban vs. rural areas. National mapping agencies are essential for supplementing rural coverage. The document acknowledges funding support and contributors to the research.
4B_1_How many volunteers does it take to map an area wellGISRUK conference
This document evaluates the quality of OpenStreetMap (OSM) data compared to Ordnance Survey data. It finds that for major roads, 80% of OSM data falls within a 20m buffer of Ordnance Survey data. For smaller roads, completeness increases with more users per area, but positional accuracy does not clearly increase above 5 users per area. While OSM data quality is high in areas with aerial imagery, Linus' Law about quality increasing with more users does not seem to directly apply to OSM. More research is needed on quality with fewer users and without aerial imagery.

1) The document discusses uncertainty in geographic classifications like the UK's Output Area Classification (OAC) system. It notes how few real-world areas perfectly fit the definitions of classification categories.
2) It presents two methods for quantifying this uncertainty - Fuzzy c-Means, which assigns probabilistic membership to multiple classes, and Possibilistic c-Means, which relaxes one of the Fuzzy c-Means constraints.
3) The author applies these methods to Leicester, England and finds that Possibilistic c-Means offers a more satisfying treatment of uncertainty in the OAC system compared to the usual hard classification approach. However, it also has some disadvantages like class areas not summing to
3A_4_Applying network analysis to quantify accessibility to urban greenspace ...GISRUK conference
This document outlines a study that aims to quantify accessibility to urban greenspace (UGS) for different socio-economic groups using network analysis. The researchers analyzed greenspace and deprivation data for Leicester, UK to determine how physical access to greenspace varies across socio-economic groups. Preliminary results found that the most deprived groups had significantly less access to greenspace than average or least deprived groups. Further work will involve public participation methods like mapping and interviews to understand how different groups use greenspace.
3A_2_Modelling health-harming behaviours in a socially ranked geographic spaceGISRUK conference
This document discusses using geodemographic classifications to model patterns of health-harming behaviors and social inequalities in health status and lifestyle within a geographic area. It aims to identify these patterns at a local scale to inform health services. The method involves defining domains of health status, lifestyle status, and social status for neighborhoods based on risk of hospitalization, lifestyle proxies, and social/economic/cultural capital measures. Applying this method to Camden, North London reveals a social gradient with neighborhoods having distinct profiles of health and lifestyle status. Limitations include overgeneralization but it offers a way to represent ranked social space and neighborhood differences to support health policy and services.
1A_3_A geodemographic classification of london primary schoolsGISRUK conference
This document summarizes research that classified primary schools in London into 14 clusters based on the socioeconomic characteristics of their pupil populations. The researchers analyzed census and performance data for all maintained primary schools in London to derive variables like free school meal eligibility, English as an additional language status, and mobility rates. They used a k-means clustering algorithm to group schools into 14 relatively homogeneous clusters based on these variables. The classification reveals differences in the profiles and performance of schools in each cluster. The researchers suggest future work could use this classification framework to further analyze relationships between schools and neighborhoods and the impact of mobility on educational attainment.
This document discusses using aerial photographs with interactive legends to better support map interpretation tasks. It aims to enrich raster images with vector data, present feature hierarchies simply, and make the legend more reflective of and supportive for the map. The conclusion is that innovative legend designs for interactive maps have potential to better support map interpretation than static legends.
SP_4 Supporting spatial negotiations in land use planningGISRUK conference
The document discusses using multi-criteria analysis (MCA) and negotiation tools to support spatial planning negotiations for land use in the Bodegraven polder region. It outlines how MCA was used to evaluate and rank alternatives, and how a negotiation workshop used a touch table and MCA results on a separate screen to facilitate interactions over exchanging parcels between intensive agriculture and nature uses. The results showed MCA output could support negotiations, the touch table facilitated knowledge exchange, and implicit and explicit knowledge combined successfully with a cooperative attitude.

This document summarizes research on automatically identifying high streets and classifying urban land use in large scale topographic databases. The research extracts urban boundaries, classifies urban block land use based on building area ratios, identifies commercial or high streets over 250m in length, and concludes with representing land use information at small map scales and enriching databases for automatic map generalization.
9B_1_Trust in web gis a preliminary investigation of the environment agencys ...GISRUK conference
This study examined trust perceptions of non-expert users interacting with the Environment Agency's "What's In Your Back Yard" (WIYBY) web GIS application. 10 participants completed tasks and questionnaires about the site. Most tasks failed and users found the site difficult to use, but they still trusted the information despite perceiving a lack of transparency. The results suggest functional attributes like maps may be less important than perceptual attributes in influencing trust of web GIS systems. Future work will test redesigned interfaces to understand how to build trust through design.
9A_2_Automatic classification of retail spaces from a large scale topographc ...GISRUK conference
This document discusses classifying different types of retail spaces using various methodologies. It aims to understand the distribution patterns of retail spaces at a national scale. The authors explore using boolean, fuzzy, and Bayesian logic to characterize retail spaces based on measures of urban centrality and accessibility. The Bayesian approach is described as determining the likelihood that an unclassified retail space belongs to a known population, like shopping malls, based on its characteristics. The conclusion suggests the Bayesian method may be best, and discusses broader applications like classifying other urban spaces and using automated techniques with open-source data.

8B_4_Exploring the usability of geographic informationGISRUK conference
The document summarizes research into exploring the usability of geographic information through a grounded theory analysis. The research identified key areas of geographic information usability including accessibility, sufficiency, and controllability. Findings were consistent with previous work and identified opportunities for future research such as developing design guidelines and user-centered design tools for geographic information.
8B_2_Using sound to represent uncertainty in address locationsGISRUK conference
The document discusses research into using sound to represent uncertainty in address location data. The researchers created an ArcGIS extension to represent the positional accuracy of addresses using different piano notes. They evaluated this approach with 49 users through a survey comparing visual and sonic representations. The results showed that users performed better when a higher proportion of the data was represented and with sonic versus solely visual representations. Areas for further research include improving the sounds used and applying this approach to other datasets.

11. Conceptual model for defining a cohesive framework between land use activity & space syntax graphs
For many years, the rhetoric surrounding planning decisions in town centres has been driven primarily by retail activity. It is a commonly held belief that retail activity is the primary generator of the vitality and viability of high streets. In reality the composition of activities of town centres and their hinterlands are much more intricately interwoven. Indeed, initial analysis, conducted as part of the Towards Successful Suburban Town centres project, found that suburban town centres are complex, distinct centres comprised of multi-scaled interactions between land use activities, population and its built environment. This complexity of interactions contributes to the vitality of such centres as places for living, working, shopping and leisure (Vaughan et al, 2009).
To explore the detailed multi-scaled interactions of these centres, it is necessary to draw upon a range of methods to enable the geographical analysis of social and economic activities at various scales of accessibility and integration within the built environment. Of particular importance is the notion that network properties of the street plan exert an influence on pedestrian and vehicular movement patterns which have a bearing on the distribution of land use activities beyond just that of retail activity. An exploration of these relationships informs policy and planning decision making as well as urban design. The type of geographic enquiry required to further our understanding lends itself to the examination of the complex relationships between land use activity and the structure of the built environment – bringing together interdisciplinary methods found in geography and architecture. The visualisation and quantification of (sub) urban form using space syntax methodology is of particular interest. It enables the spatial structure, accessibility and connectivity of streets and the layout of the buildings to be adjoined and then compared with information about the land use activities taking place within the suburban centres and its hinterland. To understand how the entities interact together, first they must be understood and only then can we model the relationships of how they interact. The paper describes how space syntax methods developed in the field of architectural research to produce quantitative descriptions of built form and street networks can be enriched by using GIS as the mechanism for bridging between disciplines. It illustrates how the resulting structural knowledge of the built environment can complement socio-economic analysis by providing a robust geographic base for measurement and analysis. This paper describes a methodology for disciplinary integration; first through the development of a point-line algorithm used to define and model the disjoint geographical relationship of entities in suburban town centres; and then how the resulting GIS data serves space syntax analysis itself and also acts as a collaborative tool for interdisciplinary investigation. It outlines the development of a cohesive geographical framework to aid the linkages between disciplinary practices and stresses the usefulness of the line as a predictor of movement potentials and as a suitable analytical measure for exploring land use activities.
Research into the built environment has suffered due to a lack of collaboration and the incompatible nature of analytical toolsets by built environment specialists and human geographers (Jones et al., 2009). Space syntax theory and methodology is a powerful means of exploring the spatial configuration of the built environment. It uses quantitative analysis derived from graph theory and is represented by network maps (Hillier and Hanson 1984; Hillier and Iida 2005). However, for human geographers this emphasis on physical structure seemingly marginalises socio-economic processes (Soja 2001), as it seems to imply a environmental determinism associated with the discredited positivism of geography’s ‘quantitative revolution’ of the post-war period (Johnston and Sidaway 2004). The geographers’ critique is represented in figure 1(a) in which an over-determined built environment renders human activity as anonymous and mechanistic. By contrast, research in the field of space syntax argues that human geography prioritises the social construction of space at the cost of considering how this interacts with the built environment of the lived space (Hillier 2008). The world view of the human geographer, from the space syntax perspective, is illustrated in figure 1 (b) where human activity is represented against an undifferentiated background. Clearly there is a need to be sensitive to both perspectives if we are to understand the relation of the structure of the built environment to human activity, illustrated in figure 1 (c).
Urban designers – looking from a different developed a methodology known as Space Syntax. It is quantitative analysis derived from graph theory and is represented by network maps (Hillier and Hanson 1984; Hillier and Iida 2005) These are drawn by first exploring the structure of the built environment as derived by the buildings and the streets on shown in the slide. Once the physical environment has been defined a network graph is created. This network graph represents the connectivity of the open space as defined by the street network. The graph connects lines of sight as approximated by the longest Straightest paths through the street network.
The graphs visualise the connectivity of open space in the physical environment and as such can then be used to understand the different types of movement potential of people and cars through it based on different measures of connectivity. The graph can then be analysed at various scales which are used to understand movement for local, regional and national scales. They are coloured using a continuous colour spectrum where red = lots of movement potential and blue = not a lot of movement potential. This image shows the potential movement at a scale of 2 km for the town centre of Surbition. We can see the importance of the high street.
The problem faced by the Towards Successful Suburban Town Centres Project was associated to the different world views that existed between urban designers and geographers. Space Syntax is a relatively young research field having only been developed in the 1970s and so there has been little formal collaboration between differnt disciplines beyond using GIS to create thematic maps. We faced the challenge of Incompatible tool sets developed in isolation together with an inconsistent analytical framework. In order to unite the disciples, it is first necessary to identify two issues: (1) a lack of automated procedures that allow different graphical entities to be linked together [1] and (2) the absence of coherent shared methodologies and practices between the disciplines.
In order to develop a coherent perspective across disciplines we first need to model the relationship between the space syntax network and the different types of urban land uses. A coherent analytic framework based on the network was developed
So we first had to build a collaborative analytical framework with a geographical base to connect to the disparate entities; the syntax graph and the land use points ( There is no common attribute between the two entities). This is because they have dissimilar spatial forms, corresponding to the very distinct geographic components they characterise. The land uses are stored as points (figure 2b) and the space syntax graph as an abstract network of lines represents the shape and structure of the suburban built environment (figure 2c). We set out to develop a robust and consistent tool for modelling the relationship between the structure of built environment and functional land use distribution in suburban town centres.
An algorithm based on coordinate geometry was written; its purpose, to define the correct spatial relationship between the lines and the points. 3 different disparate datasets with different attributes based on a point-line search algorithm that linked space syntax graphs to the roads and then using the road names to then link the land use to the space syntax graph. Land use data was stored as points derived from the Ordnance Survey Address Layer 2 product, has a full UK address attribute.
The results of the algorithm was a new geographic base framework with a very large data matrix attached. The results were used to scrutinise the geographic relationships between the land-use and the associated movement potential of the street it is located on - so that we could better understand the relationships between movement potential and land use activity within London’s suburban town centres. We decided to explore the Local Spatial Autocorrelation between the movement and the landuse to investigate any geographical clustering for the two variables.
A number of initial finding have occurred. The first reaffirmed the geographical clustering of retail activity along highly accessible movement paths of high streets in town centres. Of particular interest to the project is the pattern of non-residential land-use that are associated with movement generation and activities. The clustering of retail activity suggests the geographical dependence of other types of non residential activity located off the high street and on locally integrated streets that are not routes where you would expect lots of through movement, indicating suburban high streets function not only as retail centres but that there is a more complex pattern of activity that ensures their vitality.
In order to explore this idea we looked at the distribution of segments according to residential and non-residential activity and also adopted ideas for ecology based on the notion that thriving eco-systems required richness of species – we also looked at the number of different types of activities that occured on each segment – to gain an understanding of activity richness. The initial results reveal a clear longtail we there are fewer non-residential segments with fewer segments with have a larger number of different activities
To get more understanding on the general pattern of non-residential activity a bi-variate LISA analysis was performed between the land uses classed as non-residential and the to paths of movement potential in Town Centres The results demonstrate that routes through a town centre integrated at a scale of 1km are clustered significantly with all non-residential land uses activity. This reveals the importance of active segments beyond that of the retail High Street. This suggests that there is geographical dependence of other types of non residential activity located off the high street and on locally integrated streets that are not routes where you would expect lots of through movement, This maybe evidence that suburban centres not only function not only as retail centres but that there is a more complex pattern of activity that ensures their vitality.
The results of the algorithm led to the development of a coherent data structure based upon the network of movement potential in each town centre. The line entity became the object of priority and is symbolic of the linkages between disciplines. Thus, it is the semantic meaning of these two geographical objects that is of relevance to this paper. This fusion of the disciplines, the results of the geometric algorithm, represents the creation of a new phenomenon. The developed algorithm facilitated the amalgamation of two quite different world views with incongruent analytic frameworks. In one discipline the line object provided the mechanism for understanding the morphological properties of the town centres and in the other the point afforded investigation of the socio-economic properties of a centre’s land use activities. Up until this point the two disciplines had not been as fully synthesised. Furthermore linking the two disciplines produced findings with new insights that otherwise would not have been revealed. This synthesis between the disciplines also led to the development of a useful and usable analytical framework centred upon the line object. Thus, proving GIS as feasible mechanism for collaboration between Space Syntax and Human geography. GIS assisted in the development of automated procedures to allow the linking of different entities and the formulation of coherent shared methodologies and practices between the disciplines. The methodology developed in this paper contributes to the debate on the usefulness of GIS as a basis for driving collaborative research, illustrating how a geographical framework can be used to develop a methodology that is mutually beneficial for human geographers and space syntax specialists alike.
