  1. 1. Methods for assessing the consistency of the New National Height Model

    University essay from KTH/Fastigheter och byggande

    Author : Sandra Rangelova; [2021]
    Keywords : DEM; LiDAR; Air-borne LiDAR; strip adjustment; quality control; DEM; LiDAR; Luftburna LiDAR; bandjustering; kvalitetskontroll;

    Abstract : Digital Elevation Models (DEM) are a simple representation of the Earth’s surface. DEMs play an important role in the field of remote sensing and GIS and are used as basis for mapping and analysis for a vest majority of scientific applications. READ MORE

  3. 2. Beslutsstöd för att finna diken och bedöma behov av dikesrensning

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Elias Hannus; [2019]
    Keywords : hydrologi; erosion; flödesschema; markfuktighetskarta; höjdmodell; bildtolkning; hydrology; erosion; flow chart; soil moisture map; digital elevation model; image interpretation;

    Abstract : En betydande areal torvtäckt mark dikades i Sverige under första halvan av 1900-talet i syfte att omvandla myrimpediment till produktiv skogsmark. Många av dikena hos markvärden för denna studie, Svenska Cellulosa AB (SCA), är nu i behov av rensning för att produktionen skall bibehållas. Rensning medför också allvarliga miljörisker. READ MORE

  4. 3. Risk mapping of phosphorus leakage - improved method using a Digital Elevation Model

    Author : Håkon Jarvis Westergård; [2018]
    Keywords : ;

    Abstract : This thesis concerns the implementation of an pre-analysis tool in orienteering for the problem of finding the optimal route choice on a leg in orienteering. The problem is modelled by the framework of level sets and an anisotropic travel time equation is proposed. READ MORE

  6. 5. Changes in the Cold Surface Layer on a Polythermal Glacier during Substantial Ice Mass Loss

    University essay from Uppsala universitet/Institutionen för geovetenskaper
