3. 2. On Optimisation and Design of Geodetic Networks

   Författare :Mohammad Amin Alizadeh Khameneh; Mehdi Eshagh; Lars E. Sjöberg; Stig-Göran Mårtensson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Sammanfattning : Optimisation of a geodetic network is performed to provide its pre-set quality requirements. Today, this procedure is almost run with the aid of developed analytical approaches, where the human intervention in the process cycle is limited to defining the criteria. LÄS MER

4. 3. Mold2012 : a new gravimetric quasigeoid model over Moldova

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

   Sammanfattning : 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. LÄS MER

5. 4. Investigation and calibration of pulsed time-of-flight terrestrial laser scanners

   Författare :Yuriy Reshetyuk; Lars E. Sjöberg; Stig-Göran Mårtensson; KTH; []
   Nyckelord :terrestrial laser scanning; error sources; calibration; coordinate precision accuracy;

   Sammanfattning : This thesis has two aims. The first one is the investigation and analysis of the errors occurring in the measurements with pulsed time-of-flight (TOF) terrestrial laser scanners (TLS). A good understanding of the error sources and the relationships between them is necessary to secure the data accuracy. LÄS MER
