  2. 16. An Analysis of Consequences of Land Evaluation and Path Optimization

    Author : Rachel Mundeli Murekatete; Takeshi Shirabe; Gerhard Navratil; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Least-cost paths; Most-suitable paths; Raster cost surfaces; Raster suitability surfaces; Shortest path problem; Minimax path problem; Scales of measurement; Minsta-kostnad rutter; Mest-lämpliga rutter; Raster kostnadsytor; Raster lämplighets ytor; kortaste vägen problem; Minimax väg problem; Mätskalor; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : Planners who are involved in locational decision making often use raster-based geographic information systems (GIS) to quantify the value of land in terms of suitability or cost for a certain use. From a computational point of view, this process can be seen as a transformation of one or more sets of values associated with a grid of cells into another set of such values through a function reflecting one or more criteria.

  4. 17. Model and Reality : Connecting BIM and the Built Environment

    Author : Gustaf Uggla; Milan Horemuz; Patric Jansson; Väino Tarandi; Alojz Kopáčik; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geodesi; Geodesy;

    Abstract : The adoption of building information modeling (BIM) in the architecture, engineering, and construction (AEC) industry is changing the way informa-tion regarding the built environment is created, stored, and exchanged. In short, documents are replaced with databases, processes are automated, and timelines become more circular with an emphasis on managing the life cycles of all manufactured objects. READ MORE

  5. 18. Connecting digital and physical representations through semantics and geometry

    Author : Gustaf Uggla; Milan Horemuz; Helén Rost; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : The fields of geodesy and building information modeling (BIM) meet each other in the intersection between the physical and the digital world. Within the construction industry, the role of geodesy has typically been to describe the position of assets and to transform the geometries of those assets between coordinate systems suitable for design and coordinate systems with a known relation to the Earth.

  6. 19. An Isostatic Earth Crustal Model : and Its Applications

    Author : Mohammad Bagherbandi; Lars E. Sjöberg; Martinec Zdeněk; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Crustal thickness; inverse isostatic problem; isostasy; isostatic compensation; Moho depth; Moho density contrast; downward continuation; Earth sciences; Geovetenskap;

    Abstract :  The Mohorovičič discontinuity (Moho), which is the surface separating the Earth’s crust from the mantle, is of great interest among geoscientists. The Moho depth can be determined by seismic and gravimetric methods. READ MORE

  7. 20. Mold2012 : a new gravimetric quasigeoid model over Moldova

    Author : Uliana Danila; Lars E. Sjöberg; Stig-Göran Mårtensson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; geoid; quasigeoid; KTH method; corrective surface;

    Abstract : In order to be able to use the operational Moldavian GNSS Positioning System MOLDPOS efficiently for the determination of normal heights in surveying engineering, e.g. during the construction of a road, an accurate quasigeoid model is needed. READ MORE
