A comparative study among computation techniques for deformation analysis based on repeated geodetic observations (original) (raw)

Abstract

Considering the relative movement of points on the Earth's surface as a source of information for deformation analysis of the crust via strain analysis, geodetic obser-vations (ground based, and satellite) can provide the required geometrical data. In the literatures so far various computational techniques have been introduced to the defor-mation analysis based on repeated geodetic observations. In this paper we present a comparative study over those computations techniques. Strain component computa-tions based on displacement vector, strain component computation based on changes in the distances and angles between geodetic network stations in two epoch of time, strain component computation on the topographic surface of the Earth, and strain com-ponent computation on the map projection planes are among the those computational techniques that have been studied for their efficiency and reliability in deformation analysis, in this paper.
