Presented at the 46th Society of Cartographers Summer School in Manchester on September 10 2010. The abstract for the talk was as follows: "OpenStreetMap is coming of age, but as it starts to be used more in the mainstream, the age-old questions of quality and completeness are coming to the fore. A range of data sources have been used to build up the map in the UK, from GPS traces to aerial imagery, historic mapping, NaPTAN and the OS Open Data release, each with their own benefits and limitations. This talk looks at a number of studies and tools developed to quantify, compare and address accuracy and coverage of the project in the UK, in an attempt to answer the key questions - is it complete yet and just how good is it?"
[MIPRO2019] Map-Matching on Big Data: a Distributed and Efficient Algorithm w...University of Bologna
In urban mobility, map-matching aims to project GPS points generated by moving objects onto the road segments representing the actual object positions. Up to now, map-matching has found interesting applications in traffic analysis, frequent path extraction, and location prediction. However, state-of-art implementations of map-matching algorithms are either private, sequential or inefficient. In this paper, we propose an extension of an existing serial algorithm of known efficiency by reformulating it in a distributed way, in order to achieve great scalability on real big data scenarios. Furthermore, we enhance the robustness of the algorithm, which is based on a first-order Hidden Markov Model, by introducing a smart strategy to avoid gaps in the matched road segments; indeed, this problem may occur under sparse GPS sampling or in urban areas with highly fragmented road segments. Our implementation is based on Apache Spark and is publicly available on Github. The implementation is tested against a dataset with 7.8 million GPS points in Milan.

MiPlEx - Online Task Planning for Exploration Tasks in Urban TerrainFlorian-Michael Adolf
This presentation shows an online multi-query path planner for exploration tasks planned onboard an unmanned helicopter. While the desirable properties of roadmaps can be exploited in offline path planning, the dynamic nature of exploration scenarios hinders to utilize conventional roadmap planners. Hence, the presented path planning approach utilizes a deterministically sampled roadmap which is dynamically indexed in real time. To address situations of partial terrain knowledge, the roadmap can be extended from its a priori dimensions towards locations of unknown terrain that are outside its original, a priori boundaries. The multi-query property of the planning system allows for combinatorial optimization such that a rapidly acting decisional autonomy is achievable during exploration flights. D*-Lite is used as dynamic heuristic path searcher in order to re-plan efficiently. Inspired by the original work on this path search algorithm, the roadmap graph is augmented with an exploration vertex which steers the exploration behavior of the vehicle. As a result, the presented roadmap guides an unmanned rotorcraft through a priori unknown urban terrain in real time.

GRASS and OSGeo: a framework for archeologyMarkus Neteler
Use of GIS and geospatial data in archeology. Contribution to:
Quarto Workshop Italiano "Open Source, Free Software e Open Format nei processi di ricerca archeologica", Roma, 27 e 28 aprile 2009. Sede centrale del Consiglio Nazionale delle Ricerche (CNR)
http://www.archeo-foss.org/
Abstract:
With the widespread availability of desktop GIS, archaeologists have gained the tools to comprehensively analyze the important spatial component of their data. Initial archaeological use of GIS was (and still is in many instances) for making maps of archaeological sites. Rather quickly GIS became used for predictive modeling of site locations. More recently, viewshed analysis has seen increasing use, in efforts to understand prehistoric perceptions of the landscape.
In the last years, Open Source GIS software evolved to a powerful set of software products which support both scientific as well as common GIS users. In particular, the integration of GIS with image processing capabilities, geospatial data analysis, database management system and Web mapping software enables archaeologists to perform their tasks in a completely free environment. Since 2006, the Open Source Geospatial Foundation (OSGeo) operates as umbrella foundation for Web Mapping, Desktop GIS Applications, Geospatial Libraries, Metadata Catalog as well as the Public Geospatial Data project and the Education and Curriculum project.
In our presentation, we focus on GRASS GIS (http://grass.osgeo.org/) for spatial data analysis and visualization. GRASS is the largest Open Source GIS program currently available. The new version GRASS 6.4.0 is interoperable as it supports all common vector and raster GIS formats. Its capabilities cover raster and volume spatial analysis and modeling, time-series and landscape analysis, image processing, and visualization of 2D and 3D (voxel) raster data. Vector data can be digitized, extracted, extruded to 3D, and vector networks analyzed. Vector data are handled topologically. Vector attributes are stored in internal or externally connected databases. All general GIS tasks like map reprojection, georeferencing, and transformations are available for raster and vector data. The data storage concept of GRASS permits for single as well as multi-user access set up via network file system.
GRASS 6.4.0, the new stable release after more than one year of development and testing, brings a number of exciting enhancements to the GIS. Besides the hundreds of new module features, supported data formats, and language translations. The 6.4.0 release also runs in MS-Windows, a new installer is provided. A new graphical user interface with integrated location wizard and new vector digitizer is also included.
The presentation concludes with a series of applications relevant to archaeology including image processing, Lidar data analysis, fast viewshed analysis and more.
JCDL 2011: Semantically Augmented Annotations in Digitized Map Collectionsaboutgeo
Historic maps are valuable scholarly resources that record information often retained by no other written source. With the YUMA Map Annotation Tool we want to facilitate collaborative annotation for scholars studying historic maps, and allow for semantic augmentation of annotations with structured, contextually relevant information retrieved from Linked Open Data sources. We believe that the integration of Web resource linkage into the scholarly annotation process is not only relevant for collaborative research, but can also be exploited to improve search and retrieval. In this paper, we introduce the COMPASS Experiment, an ongoing crowdsourcing effort in which we are collecting data that can serve as a basis for evaluating our assumption. We discuss the scope and setup of the experiment framework and
report on lessons learned from the data collected so far.

Haw GIScience lost its interdisciplinary mojo?Muki Haklay
These are the slides from my talk at the GISCience 2016 conference. There is more information on my blog, but the abstract is:
Over the past 25 years, I have experienced an inside track view of two interdisciplinary research fields: Geographical Information Science (GIScience) and Citizen Science. Over that period, I was also involved in about 20 multidisciplinary, cross-disciplinary, interdisciplinary, and transdisciplinary projects. As a result, I also found myself evaluating and funding x-disciplinary projects.
On the basis of these experiences, I’d argue that Interdisciplinarity is always hard, risky, require compromises, accommodations, listening, and making mistakes. The excitement from the outputs and outcomes does not always justify the price. Frequently, there is no-follow on project – it’s been too exhausting.
Considering the project level challenges, viewing interdisciplinary areas of studies emerging is especially interesting. You can notice how concepts are being argued and agreed on. You can see what is inside and what is outside, and where the boundary is drawn. You can see how methodologies, jargon, acceptable behaviour, and modes of operations get accepted or rejected – and from the inside, you can nudge the field and sometimes see the impact of your actions.
GIScience was born as an interdisciplinary field of study, and the period of consolidation that I have seen was supposed to lead to stability and growth. This did not happen. Take any measure that you like: size of conferences, papers – or even the argument if the field deserve a Wikipedia page. Something didn’t work.
In contrast, Citizen Science is already attracting to its conferences audience in the many hundreds – the Citizen Science Association include 4000 (free) members, The European Citizen Science Association 180 (paid) – and that is in the first 2 years since they’ve established.
In the talk, I explore the way in which interdisciplinary projects and fields work, highlight the similarities and differences, and suggest the issues that have led to the outcomes that we see today
OpenStreetMap and CycleStreets: collaborative map-making and cartography in t...CycleStreets
Abstract: The arrival of web-based mapping from Google and others has revolutionised, in the space of only five years, the way many people interact with maps and map data. And the success of projects such as Wikipedia highlight how collation of small amounts of information from large numbers of people - an approach called 'crowdsourcing' - can challenge traditional models of data collection and ownership. Bringing these concepts together is OpenStreetMap, a collaborative project to create a free editable map of the world. Well-established enterprises such as the Ordnance Survey are coming under increased pressure from this new model, and large companies such as MapQuest and Microsoft are starting to use and invest in it. Martin Lucas-Smith, Webmaster in the Department, and one of two main developers of the leading UK-wide cycle journey planner website, CycleStreets, will discuss OpenStreetMap, its use within a wide range of systems (from cartography, routing, and even its central role helping deal with the Haiti disaster) and discuss the challenges it poses to traditional forms of cartography and data collection.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

2. Contents Quality & Completeness Sources of Data Scans of Imagery for Tracing Imports Studies, Tools and Methods Comparison Other Considerations OSM in the Real World
3. Quality & Completeness OpenStreetMap – a crowdsourced spatial database of the world. How good is the data compared with real life? Is everything important on the ground in the database?
4. GPS Traces In the beginning (~2004) Tracks from GPS receivers Consumer-grade handheld devices Prone to random and systematic error Particularly in urban areas (multipath) Particularly if walking Walk both ways down street, take the “average”? In theory quality improves with multiple traces Metadata doesn’t include measured quality eCourier van GPS traces for London
8. Out-of-Copyright Map Tracing Crown Copyright expires after 50 years Not so useful for urban areas Great for rural areas – less likely to change Old, low resolution map better than nothing Started with Richard Fairhurst’s collection in early 2006 Quality dependent on scan resolution and quality of rectification Paper warps, especially over 50 years
10. Yahoo Aerial Imagery Tracing Agreement in late 2006 that allowed tracing In the UK, some large urban areas covered Accuracy better than GPS but not as good as newer imagery sets (e.g. Google) Phantom roads Hidden barriers
11. Yahoo Aerial Imagery Tracing Coverage of many countries Iraq: “The whole road and rail network of the Baghdad area has been mapped using the Yahoo! imagery. As have some parks, forested areas, etc.” Australia (Sydney): “Completion of the greater metropolitan railway network… several complex road interchanges not practical to map on the bike”
13. NaPTAN Public transport nodes Once-off copy of DtT database in 2009 Most useful for “less glamorous” bus stops as railway station coverage was already complete in OpenStreetMap Rich metadata Envisaged as two-way, OSM would fix poor locations and might be fed back Imported on a county-by-county basis
14. NaPTAN NOVAM-Viewer Bus stops For reconciling NaPTAN/OSM Graphical tool Manage manual verification of the locations and metadata
15. Walking Papers Designed for large scale POI addition The source is annotations to existing OpenStreetMap data so ultimately dependent on the other sources Specially rendered to print out and add Points of Interest to Automatic georeferencing for tracing If you want it
17. Imports A common theme so far – tracing Inherently poor quality due to user error Tiger (U.S.) AND (Netherlands) OS Open Data
18. Tiger (U.S.) From US Government Imported in late 2007 (data from 2005) Data quality low but good coverage More difficult to create a community to fix rather than map Specialist tools: CloudMade has realised potential of a cleaned-up set and has created web tools to help [animation]
19. AND (Netherlands) July 2007 Relatively straightforward as there was little existing OSM mapping for the Netherlands From a digital mapping data company with navigation and LBS products First “complete” country in OSM “15-20m” offsets in places between Yahoo aerial imagery and the AND data
20. OS OpenData (U.K.) No bulk imports (c.f. Andy Robinson) Community still debating UK coverage already too comprehensive Possible licensing concerns Building outlines possibly the biggest win Some test imports – automated feature detection from Street View rasters Isle of Sheppey
23. Studies on Quality MukiHaklay (UCL CEGE) “Haklay, M., 2010, How good is volunteered geographical information? A comparative study of OpenStreetMap and Ordnance Survey datasets” Environment and Planning B: Planning and Design 37(4) 682 – 703 “on average within about 6 m of the position recorded by the OS, and with approximately 80% overlap of motorway objects between the two datasets” Analysis in 2008 (Meridian 2)
24. Studies on Quality MukiHaklay and AamerAther Beyond good enough? Spatial Data Quality and OpenStreetMap data OSM vsMasterMap I.T.N., looking at road lengths “The analysis shows that when A-roads, B-roads and a motorway from ITN are compared to OSM data, the overlap can reach values that are over 95%. … OSM is of better quality than Meridian 2.” “Positional accuracy is satisfactory for many applications. Attribute accuracy is also satisfactory.” Spring 2009
25. Studies on Quality “Just how good is it?” As good as many consumer-grade online mapping websites Depends on the care and keenness of the “local champion”
26. Studies on Completeness MukiHaklay Completeness in volunteered geographical information – the evolution of OpenStreetMap coverage (2008-2009) “OpenStreetMap already covers 65% of the area of England, although when details such as street names are taken into consideration, the coverage is closer to 25%. Significantly, this 25% of England’s area covers 45% of its population.” Affluence bias Covers to October 2009
27. Studies on Completeness MukiHaklay: OSM vs Meridian 2 (red) Left: Features only Right: With attributes
28. Studies on Completeness Peter Reed DfT highway length figures per county “Is it complete yet?” Depends on what you need Depends on where you need it Improving!
31. Getting Completeness Mapping Parties May 2006: “Mapchester” Chris Perkins, Andy Robinson January 2007: Central London Steve Chilton Richard Fairhurst May 2009: Milton Keynes Me, Andy, Steve October 2009: Atlanta
34. Getting Completeness London Mapping Marathon series One hour of mapping followed by pub 2008: Streets 2009: POIs 2010: Building outlines Build and keep the community Crises January 2010: Haiti earthquake High quality aerial imagery
35. Comparison Quality vs Google Maps POIs (Over)simplification of roads Completeness vs Google Maps POIs again Databases vscrowdsourcing Coverage… A few surprises – Pyongyang in OSM
38. It Started Life as a Street Map It’s not Ordnance Survey MasterMap Roads are line features, not areal Not yet, anyway OpenStreetMap is just a database Anything can go in it…
40. Loose Taxonomy Need to consider the metadata too – is it on the map, is it in the right place, is it tagged appropriately? Community proposes and documents on wiki but doesn’t enforce Worldwide considerations Metadata sometimes present for source, always present for input/update date & user
41. Loose Taxonomy Partial order ensured by Steve Chilton’s OSM Mapnikstylesheet If you want to see your data appear on the map that “most” people see, follow the guidelines
42. Curves ...or lack of... Ability to tag ways as curved Still straight lines in DB
44. CycleStreets “We'll be launching a page for Local Authorities v. soon about embedded versions of the CycleStreets planner on their sites” - CycleStreets
45. Skobbler Commercial Sat-Nav application based on OSM data with custom additions Motorway lanes for junction approaches Completeness crucial Display Google Maps on website for address finding (Google Local) but use OSM for routing and app 3D view Accuracy not so important
47. Skobbler Started in Germany The map is more complete Just launched in U.K. The map is probably good enough, though missing a lot of turn restrictions Users report bugs Skobbler fix remotely or highlight to OSM Both communities benefit
