A relevant issue in Remote Sensing (RS) and GIS is related to the analysis and the characterization of Land Use Land Cover (LULC) changes, very useful for a wide range of environmental applications and to efficiently undertake landscape planning and management policies. The methodology described has been applied to a case-study conducted in the area of the Province of Avellino (Southern Italy). Firstly, aerial photos and Landsat imagery have been classified to produce LULC maps for a fifty-year period (1954÷2004). Then, through a GIS approach, change detection and spatiotemporal analysis has been integrated to characterize LULC dynamics, focusing on the urban-rural gradient. This study has shown that LULC patterns and their changes are linked to both natural and social processes whose driving role has been clearly demonstrated: after the disastrous Irpinia earthquake (1980), local specific zoning laws and urban plans have significantly addressed landscape changes.

Gis and remote sensing tools to analyze landslides
This document discusses the use of GIS and remote sensing tools to analyze landslides. There are three main causes of landslides: geological factors related to rock/soil strength, morphological factors related to slope and vegetation, and human activities like construction. GIS and remote sensing can be used to map landslide hazards by analyzing contributing factors at different scales from national to site-specific. The methodology involves defining objectives, selecting an appropriate analysis scale, collecting relevant data layers, and producing hazard zonation maps showing susceptibility and probability of landslides.
Using GIS for Civil/Environmental Projects
The document discusses using GIS for a bridge inventory project for the City of New Haven, CT. Key project elements included collecting location and condition data for bridges during site visits, developing a database and summary reports, prioritizing bridges, and delivering the results in a digital map format to help the city manage its bridge infrastructure. The GIS approach integrated data on bridge locations, conditions and priorities to provide a comprehensive inventory and assessment tool.

Mapping Landscape Change: Dornoch Point
The document summarizes a study that assessed landscape change at Dornoch Point, Scotland over different timescales up to 2010. High water lines, edges of vegetation, and areas of gain and loss were digitized from historical maps and imagery. Key findings included considerable growth of Dornoch Point over time due to sediment deposition, causing the spit to extend further south. The edge of vegetation migrated southward as the dune stabilized new areas of deposited beach sediment.

This document discusses the application of GIS in environmental studies. GIS allows for spatial data analysis and overlay of environmental data on digital maps. It can be used to identify hazards, risks, and areas requiring protection. GIS supports environmental assessment, monitoring, and mitigation activities. Field studies can utilize GIS with GPS to accurately map environmental damage. As a case study, the document examines land use/cover changes over time in three regions of Guinea, Africa using GIS analysis of maps and satellite images from different periods. It finds degradation and disturbances, and concludes GIS can help detect changes and potentially propose solutions.
Paper presentation
The document discusses how GPS technology developed by NASA can be used to estimate soil properties and support large construction projects. Specifically:
1) NASA developed sensors that can estimate soil properties by analyzing GPS signals reflected off the Earth's surface.
2) Testing showed strong correlations between ground measurements and reflected GPS signals, demonstrating this technique's potential for real-time nonintrusive soil monitoring.
3) The mining industry has adopted GPS for surveying, machine guidance, and safety applications like hazard avoidance and collision prevention by continuously tracking equipment locations.
Application of GIS in Modelling Landuse Changes Of Gurupavanapuri, Kerala, India
The Project Presentation focuses on the land use and land cover change pattern of Gurupavanapuri and environs, an area which is in the State of Kerala , India.
The work was mainly aimed to identify the rapid urbanization that took over in the Gurupavanapuri and its environs during the year 2002 and 2017 and on analysis there was a clear reduction of natural vegetated area due to the human influenced constructions.
The Project was completed using The ArcGis which is a GIS application. Remote Sensing data collection, such as SRTM DEM, ETOPO1 data (Bathymetry and Oceanic bedrock surface) has been achieved.

This document summarizes a study that monitored the proliferation of slums in the Rural Common of Sidi Taibi, Morocco using GIS and satellite image processing. Unsupervised and supervised image classification techniques were used to generate land use maps from satellite imagery from 2000 to 2012. Digital terrain models were also created from topographic maps and orthophotographs. Integrating this geospatial data with socioeconomic data in a GIS allowed accurate identification and monitoring of slum areas over time to inform intervention strategies. Very high resolution satellite imagery was needed to most precisely extract slum buildings. The methodology demonstrates an improved approach over traditional surveys to dynamically track informal housing development.

The document discusses testing the e-SOTER approach for soil mapping in Morocco. The e-SOTER method aims to standardize soil data collection and mapping across countries. For Morocco, the project involved characterizing landforms and parent materials from remote sensing data, correlating local soil classifications to international standards, and mapping soils at large and medium scales. Field validation found 56% accuracy for medium-scale mapping. While e-SOTER provides a framework, it has some limitations for processes like decarbonation in semi-arid areas. Overall, the project helped build soil mapping capacity in Morocco and established a database to inform projects on climate change, erosion, and land use.
Introduction to surveying
This document provides an introduction to the field of surveying. It discusses key topics including:
- The purpose of surveying is to make measurements of objects on, above or below ground to show their relative positions on paper. This helps avoid disputes over property lines, borders, and supports planning projects.
- There are two main types of surveying - plane and geodetic. Plane surveying neglects earth's curvature over small areas, while geodetic considers curvature for larger areas.
- Fundamental surveying principles include working from whole to part and taking extra care in establishing control points for accuracy. Common surveying methods are also outlined like triangulation, traversing, and different types of surveys.

The population and urbanization of Morocco are increasing very rapidly. They have risenin large cities due to heavy immigration rate from rural areas to accessjob opportunities, better education, and better health facilities. Casablanca has the most affected land use changes in Morocco because of the immigration. This paper presents anintegrated study of land use change in this city from 1986 until 2011 using topographic map sheets (1986) and satellite image (2011). The layers of landuse map (1986) were obtainedby digitization technique in ARCGIS 9.3 software. Supervised classification methodology has been employed using maximum likelihood technique in ERDAS IMAGINE (2011) to extract from the satellite image four classes which were categorized into, built-up area, public green spaces, agricultural land and water bodies. The totalarea of each class was estimated by using geometry tools of ArcGISsoftware to compare land use changes between 1986 and 2011.
IGARSS2011 OnTheUseOfPO.ppt
The document discusses using polarimetric orientation (PO) for polarimetric synthetic aperture radar (POLSAR) classification and decomposition to discriminate between built-up and non-built-up areas. It presents a method that uses the PO angles from ascending and descending orbits to identify built-up areas facing away from the radar based on a PO angle threshold. An experiment using ALOS PALSAR data over an area in Japan demonstrates the method and shows that it can effectively identify built-up areas while reducing errors compared to other thresholds.

Surveying II ajith sir class 1
This document discusses map projections and their characteristics. It defines map projections as systematic transformations of a spherical surface to a flat surface for mapping purposes. Several types of map projections are described, each with specific properties and distortions. An ideal map projection is defined as one that accurately represents distances, angles, great circles and coordinates without any distortions, but in practice no single projection can achieve this. Key factors like scale, scale factor and representing scale on maps are also covered.
Gis in urban
GIS can help improve the urban planning process in 3 key ways:
1) GIS creates a centralized database to store and organize all spatial and attribute data for a city, making it easier to access, analyze, and use for decision making.
2) Satellite images and GIS tools allow planners to rapidly map land use changes, identify areas for future development, and update infrastructure like roads over time.
3) GIS provides analysis capabilities like overlaying maps and proximity analysis that help planners experiment with development alternatives and make more rational, data-driven decisions.

The development of the urban areas is able to transform landscapes formed by rural into urban life styles and to make functional changes, from a morphological and structural point of view. Historically, urban expansion (driven by the population increase) has typically take place on former agricultural use.
A multi-temporal image dataset has been analyzed to identify the changing pattern of Land Cover (LC) during a fifty-year period (1954÷2004).
Using the analysis tools of ArcGIS, the results have been synthesized into maps of LC changes, in order to characterize the respective dynamics.
Temporal trend analysis and landscape metrics have been integrated, using ArcGIS and specific extensions: such approach has allowed to characterize landscape patterns through significant indices and to understand the changes therein.

This document summarizes a study analyzing land use/land cover changes over a fifty-year period from 1954 to 2004 in the Conca di Avellino region of Southern Italy using aerial photos and satellite imagery. Urban areas expanded significantly, especially after an earthquake in 1980, replacing agricultural land. Transportation routes and population growth contributed to urban sprawl. While cropland decreased, urban areas increased by over 75% and grass/pasture decreased by almost 30%. The results were mapped and analyzed spatially to understand dynamics and inform land management policies.

Land Cover maps supply information about the physical material at the surface of the Earth (i.e. grass, trees, bare ground, asphalt, water, etc.). Usually they are 2D representations so to present variability of land covers about latitude and longitude or other type of earth coordinates. Possibility to link this variability to the terrain elevation is very useful because it permits to investigate probable correlations between the type of physical material at the surface and the relief. This paper is aimed to describe the approach to be followed to obtain 3D visualizations of land cover maps in GIS (Geographic Information System) environment. Particularly Corine Land Cover vector files concerning Campania Region (Italy) are considered: transformed raster files are overlapped to DEM (Digital Elevation Model) with adequate resolution and 3D visualizations of them are obtained using GIS tool. The resulting models are discussed in terms of their possible use to support scientific studies on Campania Land Cover.

Current poster presents an example of Landsat TM image processing using ENVI GIS. Research area: Taipei, Taiwan. Located on the north of the island, Taipei is Taiwan’s core urban, political and economic center; population >2.6 M continuing to expand affecting urban landscapes. Research aim: spatio- temporal analysis of urban dynamics in study area during 15 years (1990- 2005) Research objective: application of GIS methodology and remote sens- ing data to spatial analysis for a case study of Taipei. Data: Landsat TM images taken from the USGS. Software: ENVI GIS. Workflow includes following steps: 1) Preliminary processing 2) Creation color composites 3) Classification using K-means algorithm 4) Mapping using classification results 5) Accuracy assessment. The preliminary data processing includes image contrast stretching, which is useful as by default, ENVI displays images with a 2\% linear contrast stretch. For better contrast the histogram equalization contrast stretch was applied to the image in order to enhance the visual quality. The analysis of landscape changes was performed by geospatial analysis. 2 satellite images Landsat TM were processed and classified using ENVI GIS. Result of classification: areas occupied by different land cover types were calculated and analyzed. It has been detected that different parts of the city of Taipei were developing with different rate and intensity. 3 different residential types of the city were recognized and mapped. The results demonstrated following outcomes: 1) intensive urban development of the city of Taipei; 2) decline of green areas and natural spaces and, on the contrary, increase in anthropogenic urban spaces; 3) not parallel urban development in different districts of the city of Taipei during the 15-year period of 1990-2005.IGARSS11_Stramondo.ppt

This document summarizes a study on analyzing urban development in Sulaimani, Iraq between 1990-2010 using satellite images. The study used Landsat images from 1990, 2000, and 2010 to measure urban expansion. The images were preprocessed including combining bands, cropping to the study area, and enhancing. The preprocessed images were then analyzed using GIS software to digitize the 1990 urban boundary and classify developed versus empty areas for each time period. This allowed calculating that development within Sulaimani's 1990 boundary was limited from 1990-2000, with a 68.7% population increase but using only empty inner-city lands. More rapid development occurred after 2003, including west and south of the original boundary.Monitoring Internal Migration in the United Kingdom
Internal migration in the UK saw modest declines in intensity from 2000-2001 to 2010-2011 according to census and administrative data, with the largest decreases for those aged 45-59. Inter-district migration distances also decreased slightly. When compared internationally, the UK's aggregate migration intensity was average. The document advocates for greater use of origin-destination census data, cross-national migration research, and consideration of scale and zonation effects in internal migration studies.
Land Consumption, Ecosystem Services and Urban Planning Policies: Preliminary...
In the contemporaneity, the issues of land or soil consumption and of the protection of areas that, within the urban areas, provide ecosystem services (ESs) is becoming increasingly important also in relationof the 2030 Sustainable Development Goals. The concept of "Ecosystem Service" appears, in this respect, a fruitful support to define the land consumption effects on the loss of functionality and of settlement quality. Following this considerations the paper presents the first results of a research developed in Tuscany and commissioned by the Regional Government. The research aims to measure the loss of ESs in connection with land use / land cover transformations, and to verify the contribution of soil consumption to these variations. The research use methodologies for elaborating of the geographical data required for territorial governance, LUCL 2010/2016 and Land Cover Flow (LCF) model and the theoretical model of the “Capacity matrix” to provide ecosystem services.

Land_Use_-_Land_Cover_Change_Analysis_of_Karur_Tow.pdf
This document summarizes a study that analyzed land use and land cover change in Karur Town, India from 1991 to 2020 using remote sensing and GIS techniques. Land use/land cover maps were created for 1991, 2000, 2010, and 2020 from Landsat satellite imagery. The area was classified into built-up land, agricultural land, barren land, and water bodies. The analysis found that built-up area increased dramatically over the study period, from 9.01 sq km in 1991 (17% of total area) to 21.02 sq km in 2020 (40% of total area), indicating increasing urbanization. Agricultural land decreased correspondingly as land was converted to urban uses. The study demonstrated the utility of remote

This document reassesses the locations and magnitudes of earthquakes in the Eastern Mediterranean and Middle East region from 1900 to 1999. The author compiled a catalog of over 5,000 earthquakes in the region, with a focus on 369 shallow earthquakes (depth less than 40 km) of magnitude 6.0 or greater. Many early earthquake locations and magnitudes from international catalogs were found to be inaccurate and have been re-evaluated based on macroseismic data and other studies. The catalog provides improved parameters for understanding seismic hazards and tectonics in the region.
A comparison of Land Cover Change in Kaski District, Nepal
Kaski, one the major cities of Nepal, major tourism place and regional headquarter of Western Development
region, attracts large population from surrounding resulting 36.4% increase in population proportion and thus, land cover
is rapidly changing in the area. The research intended to find land cover change over nine years from 2000 to 2009 as well
as possible reason for the land cover change. Landsat images were obtained from USGS Glovis, National boundary data
was clipped and dissolved selecting study area, and demographic data were obtained from Central Bureau of Statistics,
Nepal for the research. Data was analyzed using Supervised Classification method with maximum likelihood parameter.
From the result, it is concluded that the urban area has increased by 47.86% in study area with the decrease in forest area
by 26.25%. The possible reason for the land cover change can be attributed to rapid increase in population growth and
rapid urbanization. Also, decrease in water resource and barren land can also be accounted to rapid urbanization and
rapid change in land use pattern though research provides sufficient room for further research in this area of study

The document discusses urban and rural development in Italy from 1960-2010. It notes that over this period there was a large population shift from rural to urban areas, with more than 30% of the population changing locations. This demographic shift was accompanied by a decline in the number of farms, shrinking of agricultural areas, and reduction in agricultural employment. Specifically, the number of farms decreased by 62% from 1961-2010, total agricultural area declined 35%, and utilized agricultural area decreased 26%. The complex relationships between urban and rural areas make it difficult to define classifications and policies for development.Geographical Inequalities and Population Change in Britain, 1971-2011
This document outlines a project analyzing geographical inequalities and population change in Britain from 1971 to 2011. Population surfaces were created for 1971 and 2011 census data using 1km grid cells. Preliminary analyses found decreases in total population in some urban areas, and increases in unemployment and deprivation in urban areas over time. There was also a decrease in unevenness of housing tenure but an increase in unevenness of car access and overcrowding. Overall, the analyses suggest the population has become more geographically unequal over time.

Geomatics: soil consuming risk in renewable energy plants installation
As indicated in the 2009/28/EC Directive of the European Parliament and Council, ambitious energy and climate change objectives for 2020 have been stated: greenhouse gas emissions reduction for 20%, renewable energy increase for 20%, improvement in energy efficiency for 20%.
Types and "forms" of intervention on the territory, to produce energy from renewables, appear to be multiple and certainly comparable to infrastructure "linear and areal" of anthropogenic nature. It follows that, also for this purpose, the "environment consumption” is one of the main phenomena found at different levels, which add to the already growing soil consumption in our country.
Starting from this consciousness, research of potential and actual impacts, due to the installation for energy production from renewable sources, in a modern land management, must focus on assessing the landscape ecology. A significant problem for some types of plants, mainly those solar and wind power, is the need to install the devices in the environment, with possible negative effects in terms of visual impact and soil consuming. Careful planning to individuate the less invasive and less “visible” plants integration" could reduce the problem, but certainly not eliminate it. It is therefore extremely important to define what weight can have different impacts on the environment, however, considering all possible options.

This document presents an approach for developing decision support systems (DSS) to predict risks from interactions between environmental and technological systems. The goal is to integrate systems for risk assessment based on event prediction and impact analysis. Several case studies are described that use modeling and simulation techniques to forecast crisis scenarios from extreme weather, earthquakes, or nuclear accidents. Impacts on critical infrastructure and populations are estimated. The document argues this multidisciplinary approach will enable more effective risk management and crisis response tools.

Abstract:
L’utilizzo delle tecniche di Telerilevamento, unitamente con GIS e metriche del paesaggio, è di fondamentale supporto per la mappatura della copertura del suolo e l’analisi multitemporale dei cambiamenti occorsi. In questo contesto, viene descritto il caso di studio relativo all’area della Conca di Avellino. Per studiare i cambiamenti nell’uso del suolo verificatisi nell’arco di un cinquantennio (1954÷2004), è stato processato un dataset multitemporale di foto aree (1954) e immagini Landsat (MSS 1975, TM 1985 e 1993, ETM+ 2004). I risultati hanno permesso di analizzare le dinamiche di matrice naturale e antropica intervenute nel territorio, molte delle quali legate agli strumenti urbanistici varati dopo il terremoto dell’Irpinia dell’80.

In this presentation, a seismic vulnerability assessment at large scale is described, within the SIMURAI project. A field survey was carried out in order to gather detailed information about geometric characteristics, structural typology and age of construction of each single building. An airborne Remote Sensing (RS) mission was also carried out over the municipality of Avellino, providing a detailed estimate of 3D geometric parameters of buildings through a quite fast and easy to apply methodology integrating active LIDAR technology, aerophotogrammetry and GIS techniques. An analytical seismic vulnerability assessment procedure for Reinforced Concrete buildings is illustrated and applied to the building stock considering (i) field survey data (assumed as a reference) and (ii) LIDAR data combined with census data as alternative sources of information, according to a multilevel approach. A comparison between the obtained results highlights an acceptable scatter when data provided by RS techniques are used.

The recent advances in geo-informatics have been opening new opportunities in earthquake early warning and emergency management issues. In the last years, the geo-scientific community has recognized the added value of a geo-analytic approach in complex decision making processes for critical situations due to disastrous natural events such as earthquakes. In fact, recently, GIS-based solutions are investigated in several research projects such as SIT_MEW Project, aimed at the development of volcanic and seismic early warning systems (EWSs). In this project context, an innovative open source GIS system has been investigated and developed as integrated component of the seismic EWS. Its architecture consists in a geospatial database system, a local GIS application for analyzing and modelling the seismic event and its impacts and supporting post-event emergency management, a WEB-GIS module for sharing the geo-information among the public and private stakeholders and emergency managers involved in disaster impact assessment and response management.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
