  1. 6. A Complete Model for Displacement Monitoring Based on Undifferenced GPS Observations

    Författare :Johan Vium Andersson; Lars Sjöberg; Milan Horemuz; Jan Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Undifferenced GPS observations; Real-time displacement monitoring; Early warning system; CUSUM; Surveying; Lantmäteri;

    Sammanfattning : During recent years there has been a great focus on the climate changes within the media. More or less every day more newspaper articles are presented about the global warming issue and the effect on us human race. Climate models predict higher temperatures and more rain in the northern part of Europe. LÄS MER

  3. 7. Determination of Land uplift in Areas not covered by Repeated Levellings with application to South-Norway

    Författare :Jan Danielsen; Lars Sjöberg; KTH; []
    Nyckelord :;

    Sammanfattning :  The fennoscandia post glacial uplift rate of today, the time averaged vertical velocity, is usually determined by mareographs and repeated leveling. We consider situations where parts of the levelling not are observed only once. LÄS MER

  5. 9. Self-calibration and direct georeferencing in terrestrial laser scanning

    Författare :Yuriy Reshetyuk; Lars E. Sjöberg; Milan Horemuz; Hansjörg Kutterer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; terrestrial laser scanning; self-calibration; direct georeferencing; error sources; Surveying; Lantmäteri;

    Sammanfattning : An important step in data processing from terrestrial laser scanning (TLS) is georeferencing, i.e. transformation of the scanner data (point clouds) into a real world coordinate system, which is important for their integration with other geospatial data. LÄS MER

  7. 10. Geoid Model of Tanzania from Sparse and Varying Gravity Data Density by the KTH method

    Författare :Prosper Ulotu; Lars Sjöberg; Hossein Nahavandchi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geoid; sparse gravity data; gravity database; GGM validation by gravity; corrector surface; hybrid geoid; KTH-LSMS with AC; Mt. Kilimanjaro; Tanzania.; Earth sciences; Geovetenskap;

    Sammanfattning : Developed countries are striving to achieve a cm geoid model. Most developing countries/regions think that the situation in their areas does not allow even a few decimetre geoid model. GNSS, which provides us with position, is one of the greatest achievements of the present time. LÄS MER
