  1. 1. På gränsen till framtiden – Möjligheter till koordinatbestämda fastighetsgränser

    Författare :Kristin Land; Fastighetsvetenskap; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reform; property boundary; digital cadastral map; cadastre; legal coordinated cadastre;

    Sammanfattning : In Sweden, the course of a property boundary is first and foremost determined by boundary marks on the ground, and only secondly by cadastral survey plans and measurements. In recent years, the demand for digital property information has increased substantially, not least in respect of accurate boundary data in the national cadastral map. LÄS MER

    Nyckelord :HUMANIORA; HUMANITIES; Semi-subterranean house; dwelling; settlement; history; land upheaval; meter above sea; Archaeology; Arkeologi;

    Sammanfattning : This thesis focuses on the use of the semi-subterranean house on the coast of Norrbotten during the period 5000–2000 BC. The term semi-subterranean house (in Swedish boplatsvall) became a new category of prehistoric remains in Norrbotten during the 1980s. LÄS MER

  5. 4. The Integration of 3D Geodata and BIM Data in 3D City Models and 3D Cadastre

    Författare :Jing Sun; Kent Eriksson; Anders Östman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D geodata; BIM; city models; 3D cadastre; geometric quality; CityGML; LADM; laser scanning; Geodesy and Geoinformatics; Geodesi och geoinformatik; Geodesi; Geodesy;

    Sammanfattning : The initial geographic information system (GIS) and building information modelling (BIM) are designed and developed independently in order to serve different purposes and use. Within the prolific increase and growing maturity of three-dimensional (3D) technology, both 3D geodata and BIM data can specify semantic data and model 3D buildings that are prominent for the 3D city models and 3D cadastre.

  7. 5. Precise kinematic GPS positioning with Kalman filtering and smoothing

    Författare :Patric Jansson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The Global Positioning System (GPS) has proven to be auseful tool for the determination of positions of a widevariety of moving platforms to accuracies in the order of a fewcentimetres. One of the critical aspects of precise kinematicGPS positioning at the centimetre level is the determination ofinteger carrier phase cycle ambiguities. LÄS MER
