2. 1. GNSS hardware biases in code and carrier phase observables

   Author : Martin Håkansson; Milan Horemuz; Anna B. O. Jensen; Lambert Wanninger; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GNSS; GNSS positioning; hardware biases; phase biases; multi-GNSS; GPS; GLONASS; Galileo; BeiDou; satellite dependency; characterization; android; mass market; Group delay variations; nadir dependence; ionosphere modeling; ionospheric tomography; Geodesy and Geoinformatics; Geodesi och geoinformatik; Geodesi; Geodesy;

   Abstract : GNSS hardware biases appear in code and phase observations, and originates both from the receiver and satellite hardware. The presence of biases in GNSS observations might affect the accuracy in precise GNSS positioning applications, and might also be of relevance in other GNSS applications. READ MORE

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

   Author : Jing Sun; Kent Eriksson; Anders Östman; KTH; []
   Keywords : 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;

   Abstract : 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.

5. 3. 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

6. 4. Monitoring lithospheric motions by Satellite geodesy

   Author : Nureldin A. A. Gido; Mohammad Bagherbandi; Lars E. Sjöberg; Faramarz Nilfouroushan; Hossein Nahavandchi; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geodesi; Geodesy;

   Abstract : Understanding of global and local Earth’s dynamic processes is of great importance to the Earth’s system knowledge, human life, and sustainability goals (e.g. climatic change and geo-hazard assessment, etc.). READ MORE

7. 5. Integration of BIM and 3D GIS for sustainable cadastre

   Author : Jing Sun; Kent Eriksson; Lars Harrie; Jenny Paulsson; Milan Horemuz; Peter van Oosterom; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; BIM; 3D GIS; 3D cadastre; LADM; business ecosystem; cadastre ecosystem; sustainability; Geodesi; Geodesy;

   Abstract : Building Information Modelling (BIM) has prominently innovated and digitalized buildingenvironment through digital representation of buildings, lifecycle process and managementfor involved actors. Rapidly developed from Geographical Information System (GIS) domain,three-dimensionally (3D) GIS provides powerful and comprehensive functions of planning,modelling, visualizing and analyzing 3D geodata in large scale.
