1. 41. Effective methods for prediction and visualization of contaminated soil volumes in 3D with GIS

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Sofia Sjögren; [2016]
   Keywords : Kriging; geostatistics; GIS; 3D interpolation; 3D volumes; remediation; soil contamination; Geomatics; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

   Abstract : Geographical Information Systems (GISs) have shown to be of great help in the work at contaminated sites. Today there is an increase in the development of 3D modeling in many fields. However, to combine the advantage working with spatial data in a GIS and 3D modeling for subsurface soil data is limited. READ MORE

3. 42. 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

4. 43. Geometric quality assessment of multi-rotor unmanned aerial vehicle borne remote sensing products for precision agriculture

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Jayan Wijesingha; [2016]
   Keywords : OrthoMosaic; blurriness; geometric accuracy; UAV; precision agriculture PA ; Digital Surface Model DSM ; geomatics; Physical Geography and Ecosystems Analysis; Earth and Environmental Sciences;

   Abstract : Sub-meter level spatial resolution remote sensing products are essential for Precision Agriculture (PA) applications. Recent development of Unmanned Aerial Vehicle (UAV) with imaging sensors provides opportunity to generate sub-meter level, timely, and cloud free remote sensing products. READ MORE

5. 44. 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.

6. 45. Analysis of NDVI variation and snowmelt around Zackenberg station, Greenland with comparison of ground data and remote sensing

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Georgios Konstantinos Lagkas; [2015]
   Keywords : active layer; snow; growing period; NDVI; Zackenberg; Greenland; geography; physical geography; statistical analysis; regression analysis; geomatics; Earth and Environmental Sciences;

   Abstract : Snow and permafrost are significant climatic factors affecting the climate in high latitudes and especially in arctic regions. Moreover, results of conducted scientific studies have shown that snow is crucial for photosynthetic activity and therefore vegetation vigor and growing season in arctic environments. READ MORE
