  1. 6. Fjärrmätning av spårdjup i skogsterräng med drönare och digital stereofotogrammetri

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Rasmus Wictorsson; [2019]
    Keywords : fjärranalys; hjulspår; 3D-Point Clouds; tracks; soil disturbance;

    Abstract : Markstörning i form av spårbildning och kompaktering av marken är oftast påtagliga vid maskinellt avverkade områden. Skoglig inventering och kartläggning av skogsrelaterade skador med hjälp av flygfotografering har används sedan 1970-talet. READ MORE

  3. 7. Feature detection for geospatial referencing

    University essay from Umeå universitet/Institutionen för fysik

    Author : Niklas Nilsson; [2019]
    Keywords : Feature detection; feature description; feature; image processing; digital image processing; image analysis; aerial photography; drone; Bildanalys; flygfotografi; flygfoto; bildprocessering;

    Abstract : With the drone industry's recent explosive advancement, aerial photography is becoming increasingly important for an array of applications ranging from construction to agriculture. A drone flyover can give a better overview of regions that are difficult to navigate, and is often significantly faster, cheaper and more accurate than man-made sketches and other alternatives.

  4. 8. Hydrological modeling enhancement using GIS : An improved topographic wetness index for wetland detection

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Patricia Rull; [2016]
    Keywords : Blue spots; digital dams; culverts; hydrologically enforced DEM; topographic wetness index; TWI; soil-topographic wetness index; STI; wetland detection;

    Abstract : Hydrological modeling, like runoff modelling for flood prevention, is based on digital elevation models (DEMs). The fact that the DEMs do not represent existing road culverts can lead to considerable hydrological misinterpretations. READ MORE

  5. 9. The relationship between airborne gamma-ray spectrometry data and soil moisture in forested areas of Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Åke Magnusson; [2016]
    Keywords : ;

    Abstract : Measurements and estimations of soil water content are essential information in many differentfields, however, methods for deriving such data are often limited due to scale/spatial resolution, cost and time efficiency, or the presence of a vegetation cover. This thesis examined the relationship between airborne gamma-ray spectrometry (AGRS) data and soil water content in forested areas. READ MORE

  6. 10. Do-It-Yourself Helium Balloon Aerial Photography : developing a method in an agroforestry plantation, Lao PDR

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Sofia Valentin; [2015]
    Keywords : DIY; aerial photography; remote sensing; balloon; Helium; small format aerial photography; SFPA; Laos; Field of View; FOV; Ground Control Points; GCP; UAS; Earth and Environmental Sciences;

    Abstract : Syftet med studien har varit att utveckla en metod för flygfotografering som är lätt att använda, relativt billig och ger tillräckligt högupplösta bilder för att urskilja individuella trädkronor. Flygbilder har blivit ett värdefullt verktyg för skogsförvaltning genom tiderna på grund av den fördelaktiga vyn och möjligheterna att erhålla uppdaterad information. READ MORE
