2. 1. Terrain Modelling with GIS for Tectonic Geomorphology Numerical Methods and Applications

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Gyözö Jordan; Uppsala universitet.; [2004]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

   Abstract : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. READ MORE

4. 2. Geo-environmental considerations in transport infrastructure planning

   University dissertation from Stockholm : KTH Royal Institute of Technology

   Author : Caroline Karlsson; KTH.; [2016]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Roads; Railways; Geology; GIS; Decision support; Modelling; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : Transport infrastructure constitutes one of the key factors to a country’s economic growth. Investment in new transport infrastructure might cause potential environmental impacts, and if a project has several alternative corridors open for suggestion then each alternative corridor will have a different impact on the environment.

5. 3. Airborne Gravity Gradient, Magnetic and VLF datasets Case studies of modelling, inversion and interpretation

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Sayyed Mohammad Abtahi; Uppsala universitet.; [2016]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; VLF; gravity gradient; magnetic; airborne; inversion; non-uniqueness;

   Abstract : Northern Sweden is one of the largest hosts for mineral resources in Europe and always has been an interesting area for researchers from various disciplines of Earth sciences. This dissertation is a comprehensive summary of three case study papers on airborne VLF, gravity gradient and magnetic data in the area. READ MORE

6. 4. Modelling and Retrieval of Forest Parameters from Synthetic Aperture Radar Data

   University dissertation from Uppsala : Acta Universitatis Upsaliensis

   Author : Maciej Soja; [2014]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Frequent, high-resolution mapping of national and global forest resourcesis needed for improved climate modelling, degradation and deforestation detection,natural disaster management, as well as commercial forestry. Synthetic aperture radar(SAR) is an active radio- or microwave-frequency imaging sensor, which can be optimisedto fit specific needs through the choice of the centre frequency. READ MORE

7. 5. Spatial Variation in Near-Ground Radiation and Low Temperature - Interactions with Forest Vegetation

   University dissertation from Lund University Press

   Author : Kristina Blennow; Lund University.; Lunds universitet.; [1997]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; light interception; hemispherical photograph; growth; forest fragmentation; fluorescence; cold-induced photoinhibition; GIS; view factor; radiative cooling; frost protection; agro-climatic mapping; forest clear-cut; local climate; Microclimate; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

   Abstract : Low temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. READ MORE
