  1. 26. Digitization and interpretation of vintage 2D seismic reflection data from Hanö Bay, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Nikolas Benavides Höglund; [2016]
    Keywords : seismic interpretation; Tornquist Zone; Hanö Bay Basin; seismic data; digitization of seismic sections; OPAB; Earth and Environmental Sciences;

    Abstract : Seismic reflection data has been collected for more than half a century for both scientific and industrial purposes. Data sampled in modern surveys are collected, processed and stored digitally. READ MORE

  3. 27. Comparison of forest fire severity classification models based on aerial images and Landsat 8 OLI/TIRS images of a forest fire area in central Sweden

    University essay from SLU/Dept. of Forest Resource Management

    Author : Adrian Straker; [2016]
    Keywords : forest fire; fire severity; stereo photogrammetry; digital surface model; aerial images; NDVI; NBR; Image Matching; Västmanland;

    Abstract : Due to different level of fire severity a diverse mosaic of vegetation pattern establishes after the occurrence of a forest fire. In order to study the effects of forest fires and to plan future remediation of the burned area remote assessment of forest fire severity has shown to be a valuable tool. READ MORE

  4. 28. Quantifying terrain factor using GIS applications for real estate property valuation

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Dahlia Mudzaffar Ali; [2016]
    Keywords : digital elevation model DEM ; GIS; geography; physical geography; property valuation; Earth and Environmental Sciences;

    Abstract : This thesis studies the use of GIS applications to derive adjustment figures for the terrain factor in property valuation tasks. It aims at suggesting a quantitative approach alternative to evaluate the terrain factor as opposed to traditional methods and current industry practices where terrain is qualitatively judged based on visual observation at site and subjected to individual opinion.

  5. 29. 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

  6. 30. Exploitation of Digital Surface Models from Optical Satellites for the Identification of Buildings in High Resolution SAR Imagery

    University essay from KTH/Geoinformatik

    Author : Rebecca Ilehag; [2016]
    Keywords : SAR; DSM; GeoRaySAR; nDSM; building detection;

    Abstract : Interpreting a Synthetic Aperture Radar (SAR) image and detecting buildings can be a difficult task visually. In order acquire an overview of an area that has been affected by a disaster, such as an earthquake, SAR is useful due to its independence of weather conditions and the time of the day. READ MORE
