  1. 1. Evaluation of airborne and marine gravity data over Kattegat region

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Chrishan Fonseka; [2020]
    Keywords : ;

    Abstract : The Kattegat sea region between Denmark and Sweden is identified as a region both economically and environmentally sensitive. Statistics indicate that over two thousand vessels per day navigate in the region. Navigation route optimization for the region is vital for efficient transportation. READ MORE

  3. 2. A study on the quality of the NKG2015 geoid model over the Nordic countries

    University essay from Högskolan Väst/Avdelningen för Matematik, Data- och Lantmäteriteknik

    Author : Jenny Berntsson; [2019]
    Keywords : Geodesi; modell; kvalitet;

    Abstract : Geoidmodellen NKG2015 (Nordiska kommissionen för geodesi) är den senaste geoidmodellen över Norden. Det har inte publicerats någon forskning om kvaliteten på den här nya modellen, därför kan den här studien bidra till forskningen inom ämnet. READ MORE

  4. 3. On the statistical tests over Fennoscandian GNSS/levelling networks

    University essay from KTH/Geodesi och satellitpositionering

    Author : Sedigheh Zoghi; [2015]
    Keywords : ;

    Abstract : In Geodesy and Surveying we work with a large amount of observations which alwayscontains different types of errors. The errors decrease the quality of the observations andpropagate to the results. Therefore, detection and removing the gross errors are of vitalimportance. READ MORE

  5. 4. Introducing Lantmäteriet’s gravity data in ArcGIS with implementation of customized GIS functions

    University essay from Institutionen för geovetenskaper

    Author : Mattias Ryttberg; [2013]
    Keywords : GIS; geodesy; lantmäteriet; gravity; model builder; modelbuilder; python;

    Abstract : Gravity is measured and used by Lantmäteriet to calculate a model of the geoid to get accurate reference heights for positioning. Lantmäteriet are continuously measuring new gravity and height data across Sweden to both complement, replace and to add new data points. This is mainly done by measurements in the field at benchmark points. READ MORE

  6. 5. Determination of a gravimetric geoid model of Kazakhstan using the KTH-method

    University essay from KTH/Geodesi och geoinformatik

    Author : Daniya Inerbayeva (Shoganbekova); [2010]
    Keywords : geoid model; least-squares modification of Stokes’ formula; the KTH-method; GPS Levelling; Kazakhstan;

    Abstract : This study work deals with the determination of the gravimetric geoid model for Kazakhstan by using the KTH-method. A number of data sets were collected for this work, such as the gravity anomalies, high-resolution Digital Elevation Model (DEM), Global Geopotential Models (GGMs) and GPS/Levelling data. READ MORE
