From the article: Abstract Adjustment and testing of a combination of stochastic and nonstochastic observations is applied to the deformation analysis of a time series of 3D coordinates. Nonstochastic observations are constant values that are treated as if they were observations. They are used to formulate …

Author supplied: "This paper gives a linearised adjustment model for the affine, similarity and congruence transformations in 3D that is easily extendable with other parameters to describe deformations. The model considers all coordinates stochastic. Full positive semi-definite covariance matrices and …

Onderzoek RPS heeft brede expertise in terrestrische landmeetkunde, maar is op zoek naar innovatieve uitbreiding van het scala aan inwinningsmethoden. Eén potentiële nieuwe techniek is het doen van deformatiemetingen vanuit de ruimte met radar satelliet metingen (InSAR). Het doel van het onderzoek …

This paper is concerned with the governance of geodetic deformation measurements. If we want to know if and how fast a country, or parts of it, are subsiding or rising, who decides that it should be measured and how is the methodology determined? What interests are at stake? How is the proper use and …
