  2. 6. Remote Sensing of Forest Decline in the Czech Republic

    Author : Jonas Ardö; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Czech Republic; neural networks; sulphur dioxide; air pollution; Norway spruce; deforestation; forest decline; GIS; spectral characteristics; Remote sensing; Landsat; Ore Mountains; Geology; physical geography; Geologi; fysisk geografi;

    Abstract : This thesis describes the localisation and quantification of deforestation and forest damage in Norway spruce forests in northern Czech Republic using Landsat data. Severe defoliation increases the spectral reflectance in all wavelength bands, especially in the mid infrared region. READ MORE

  4. 7. Applicability of Remote Sensing Techniques to Groundwater Exploration in Semi-Arid Hard Rock Terrain - A Systematic Approach

    Author : Nils Kellgren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; groundwater exploration; hard rock; semi-arid; decision support; lineaments; GIS; remote sensing; borehole siting;

    Abstract : Groundwater exploration in hard rock terrain involves complex decisions, attributable to a lack of reliable data and the heterogeneous nature of the geological environment. Targets for drilling of boreholes are commonly selected on the basis of knowledge, or perceptions, of groundwater occurrence in a specific area. READ MORE

  6. 9. Spatial distribution of water resources and accessibility to water. The case of Bugesera district in Rwanda

    Author : Jean Paul Dushimumuremyi; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Water resources; access to water; GIS; remote sensing; Bugesera; Rwanda;

    Abstract : This study deals with issues related to water resources and the accessibility to water in Bugesera district, a rural area of Rwanda. The research problem focuses on why people in Bugesera face perpetual problems related to water shortage. The research focuses on physical and socio-economic factors affecting people’s access to water. READ MORE

  7. 10. Monitoring biodiversity in cultural landscapes: development of remote sensing- and GIS-based methods

    Author : Jonas Dalmayne; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : Remote sensing; statistical modeling; spatial scales; partial least squares; support vector machines; grazed grasslands; LULC; HySpex; Worldview-2; Landsat; heterogeneity; landscape complexity; plant species diversity;

    Abstract : In this thesis, I explore the relationships between structural and compositional landscape properties, and species diversity, using remotely sensed data on a variety of spatial scales. The thesis shows that increased landscape heterogeneity, measured using environmental and spectral variables that were used both separately and combined, is generally positively related to plant species richness.
