  1. 1. Conforming building models derived in Esri's environment to the Swedish national specification for 3D data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Gudrun Jensdóttir; [2021]
    Keywords : Geomatics; GIS; 3D building models; 3D city models; conversion; Esri FileGDB; spatial ETL; FME; MultiPatch; national standard; NS building; transformation; Earth and Environmental Sciences;

    Abstract : Three-dimensional (3D) city models are increasingly utilized among stakeholders of different sectors, particularly those dealing with building information. 3D city models are a three-dimensional digital representation of urban structures, most prominently buildings. READ MORE

  3. 2. Performing Geographic Information System Analyses on Building Information Management Models

    University essay from KTH/Geodesi och satellitpositionering

    Author : Jonas Bengtsson; Mikael Grönkvist; [2017]
    Keywords : BIM; GIS; 3D modelling; Coordinated visualisation; 3D analyses; IFC; CityGML; BIM; GIS; 3D-modeller; Samredovisning; 3D-analyser; IFC; CityGML;

    Abstract : As the usage of both BIM (Building Information Modelling) and 3D-GIS (Three-Dimensional Geographic Information Systems) has increased within the field of urban development and construction, so has the interest in connecting these two tools.  One possibility of integration is the potential of visualising BIM models together with other spatial data in 3D.

  4. 3. Uncertainty comparison of Digital Elevation Models derived from different image file formats

    University essay from Högskolan i Gävle/Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Author : Ted Spring; [2014]
    Keywords : UAV; UAS; DEM; RAW format;

    Abstract : Unmanned Aerial Systems (UAS) have become increasingly popular recently for surveying and mapping because of their efficiency in acquiring remotely sensed data in a short amount of time and the low cost associated with them. They are used to generate digital elevation models (DEM) derived from aerial photography for various purposes such as the documentation of cultural heritage sites, archaeological surveying or earthwork volume calculations.

  5. 4. USES: Uniview's Shader Effect System

    University essay from Medie- och Informationsteknik; Tekniska högskolan

    Author : Mir Jawad Mairaj; [2013]
    Keywords : ;

    Abstract : This thesis work details the implementation of a generic shader effect system for Uniview (a proprietary 3D graphics software for the display of astronomical data in digital planetariums developed by SCISS AB). The system enables Uniview to load a variety of 3D file formats, customize them in various ways and, using a multipass setup, create complicated effects including rainbows, shadows, orbiting meteorites etc. READ MORE

  6. 5. A comparison of 3D file formats

    University essay from Informationskodning

    Author : Marcus Lundgren; [2011]
    Keywords : Comparison; 3D file formats; COLLADA; MD2; B3D; X;

    Abstract : Choosing a 3D file format is a difficult task, as there exists a countless number of formats with different ways of storing the data. The format may be binary or clear text using XML, supporting a lot of features or just the ones that is currently required and there may be an official, or just an unofficial, specification available.
