21. Studies of Atmospheric Water Vapor Using the Global Positioning System
Sammanfattning : Atmospheric water vapor is of fundamental interest in the Global Positioning System (GPS) and Very Long Baseline Interferometry (VLBI) techniques. These techniques are based on the timing of radio waves propagating through the atmosphere. LÄS MER
22. Microwave radiometry for studies of variations in atmospheric water vapor and cloud liquid content
Sammanfattning : .... LÄS MER
23. Connecting digital and physical representations through semantics and geometry
Sammanfattning : 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.

24. Recovering Moho parameters using gravimetric and seismic data
Sammanfattning : Isostasy is a key concept in geoscience to interpret the state of mass balance between the Earth’s crust and mantle. There are four well-known isostatic models: the classical models of Airy/Heiskanen (A/H), Pratt/Hayford (P/H), and Vening Meinesz (VM) and the modern model of Vening Meinesz-Moritz (VMM). LÄS MER
25. On Optimisation and Design of Geodetic Networks
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
