More on sensitivity of a geodetic monitoring network
The sensitivity of a geodetic monitoring network is defined as its capacity to detect and measure movements and deformations in the area covered by the network. This paper attempts to study the effects of datum definition on the sensitivity of geodetic networks.
Principles from continuum mechanics are used to analyze the datum definitions required for a sensitive network, and it is shown how the sensitivity of a monitoring network is strongly influenced by the geometry of the network points.
This paper presents a new perspective and describes relevant parameters that enable defining and quantifying the influence of the datum on the sensitivity of geodetic networks.
Following an introduction of the concept of geodetic networks sensitivity and a development of theoretical tools, the paper presents the sensitivity analysis of a group of points in the network and the influence of datum definition on the sensitivity of geodetic monitoring networks.
Two main conclusions arise in the paper, the sensitivity is invariant to the datum definition and the geometric location of the network points is extremely important to the network sensitivity, as different point distributions lead to different levels of sensitivity.
