1. 21. Mapping tree canopy cover in the semi-arid Sahel using satellite remote sensing and Google Earth imagery

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Abdalla Eltayeb Abdalla Mohamed; [2017]
   Keywords : Sahel; physical geography and ecosystem analysis; tree cover; NDVI; Google Earth; Landsat 8; geomatics; Earth and Environmental Sciences;

   Abstract : Tree vegetation is an essential element in the daily life of the people in the Sahel region of Africa. It is also considered as a robust indicator of the Sahel ecosystem status and health. In this thesis, a method to estimate tree vegetation was developed and used in mapping the tree canopy cover in semi-arid Sahel. READ MORE

3. 22. Methodology for creating historical land use databases : a case study for ICOS-station Hyltemossa, Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Adriana Bota; [2017]
   Keywords : Physical Geography and Ecosystem analysis; historical land-use databases; land-use; land cover; historical maps; geomatics; Earth and Environmental Sciences;

   Abstract : This thesis studies how modern spatio temporal databases of land use changes can be created based on historical maps. The entire study was conducted based on the available maps over the study area, in southern Sweden. READ MORE

4. 23. Development of methods for flood analysis and response in a Web-GIS for disaster management

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ludvig Forslund; [2016]
   Keywords : fluvial flood analysis; dynamic street network analysis; physical geography; Web-GIS; flood disaster response; geomatics; Earth and Environmental Sciences;

   Abstract : In this thesis, two methods were developed for a web-based GIS to make the spatial perspective of flood disaster risk reduction and response accessible. Flood disaster can cause major disruption to the street network, which further affects the emergency services and evacuation work in finding the safest and fastest routes. READ MORE

5. 24. Design and development of a prototype mobile geographic information system for real-time collection and storage of traffic accident data

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Peter Markus; [2016]
   Keywords : Web-GIS; Open Source; STRADA; LBS; Android; Geomatics; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

   Abstract : Today, Swedish police authorities nationwide collect data of traffic accidents. The information is stored in a national database managed by the Swedish Transport Agency and is an important resource in the process of analysing and improving road safety. READ MORE

6. 25. Exploring the spatial relationship between NDVI and rainfall in the semi-arid Sahel with geographically weighted regression

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Stefanos Georganos; [2016]
   Keywords : geomatics; rainfall; Sahel; scale dependency; non-stationarity; physical geography and ecosystem analysis; geographically weighted regression; Earth and Environmental Sciences;

   Abstract : The Normalized Vegetation Difference Index (NDVI) is frequently used as a surrogate for vegetation properties and is often correlated with climatic variables such as rainfall. However, studies have shown that conventional regression models used to study the spatial relationship between NDVI and rainfall are often plagued by non-stationarity and are scale dependent.
