  2. 1. Detail Surveying with GPS

    Author : Kjell Almgren; Lars Sjöberg; []
    Keywords : ;

    Abstract : 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. READ MORE

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

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

    Abstract : 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.

  5. 3. A Complete Model for Displacement Monitoring Based on Undifferenced GPS Observations

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

    Abstract : 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. READ MORE

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

    Author : Boris Lorenc; Daniel Thorburn; Lars Lyberg; Gösta Forsman; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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.

  7. 5. Solutions and their ambiguities for structure and motion problems

    Author : Magnus Oskarsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surveying; navigation; autonomously guided vehicles; motion; Computer vision; structure; Mathematics; Matematik;

    Abstract : This thesis revolves around the problem of solving the structure and motion problem in computer vision. This is the problem of reconstructing the world, the structure, from images taken by a number of cameras undergoing an unknown motion. READ MORE
