  1. 1. Detail Surveying with GPS

    Författare :Kjell Almgren; Lars Sjöberg; []
    Nyckelord :;

    Sammanfattning : Abstract In the past ten years, the Global Positioning System (GPS) has revolutionized navigation and positioning at or near the surface of the Earth. Even though it is developed and authorized by the US military forces, it has found a remarkable civilian use. In most uses of GPS, the position accuracy is in the order of metres. LÄS MER

  2. 2. Height determination by GPS : A practical experiment in central Sweden

    Författare :Stig-Göran Mårtensson; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Division of Geodesy Reports; Surveying; Lantmäteri;

    Sammanfattning : GPS as a height measuring tool has been widely introduced for solving various tasks within the fields of Geodesy and Engineering Surveying. The obvious advantage of not needing lines of sight when acquiring height differences is, however, darkened by the fact that GPS and traditional spirit levelling have fundamentally different reference systems for heights.

  3. 3. 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

  4. 4. Om att förstå ett hus : den dynamiska modellen : dokumentationsmetoder, vårdplan och restaureringsideologi

    Författare :Ebbe Hædersdal; Bebyggelsevård; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heritage values; restoration ideology; restoration; presentation; interpretation; fusion of horizons; hermeneutics; personal and tacit knowledge; buildings archaeology; buildings history; colour investigation; surveying; documentation methodlogy; Architectural heritage; documentation of historic buildings; digital maintenance plans.; Building construction; Byggnadsteknik; Architecture; interior design; Arkitektur; inredningsarkitektur; Archaeology; Arkeologi;

    Sammanfattning : The principal aim of the thesis is to evaluate the significance of the documentation of a building’s history for the work of restoring it and caring for it. Thus it may be said to address restoration as a hermeneutical problem, besides considering the relationships between the work of documentation; analyses of the resulting data; and the creative process in which the ideology of restoration is important.

  5. 5. Two Topics in Survey Methodology : Inference from Nonprobability Samples Using the Double Samples Setup

    Författare :Boris Lorenc; Daniel Thorburn; Lars Lyberg; Gösta Forsman; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; response process; establishment surveys; socially distributed cognition; response burden; measurement error; nonprobability samples; web surveys; double samples; propensity scores; model-based estimation; imputation; nonparametric imputation; weighting; Surveying; Lantmäteri;

    Sammanfattning : Modelling the response process in establishment surveys proceeded thus far by adding steps of operational character to the core cognitive steps of the individual cognitive model. Here (Paper 1) a larger unit of the cognitive analysis is posited: that part of the enterprise that is engaged in responding to a survey, consisting of one or more employees, the tools they use and the established practices of record keeping and survey responding.
