About geodetic deformation measurements

Governance

Geodetic deformation measurements (monitoring of deformations of what is above, on or below the earth's surface) are performed in many domains. There are differences between these domains. The extraction of gas, oil and salt is done under a highly prescriptive legislation, which is lacking in most other domains. In civil and commercial construction a strong influence is felt of private parties, including insurance. The national infrastructure is heavily controlled by the government, but the influence of private parties is growing. These differences affect the governance, the techniques used for geodetic monitoring, the standardization and the communication. What are the differences and why do the exist?

Geodetic-mathematical models

Nederlandse Aardolie Maatschappij (NAM) analyses the subsidence measurements since the early sixties with increasingly sophisticated mathematical models. There are intense discussions between geodesists and geophysicists on the modelling and interpretation. Discussions are settled on a scientific level.
In most other domains the used mathematical models are often simpler, so simple, that the question is justified, whether they are acceptable. Why is this so and can it be done better? How can value be given to the geodetic measurements?
An analysis of mathematical models used and the design of generic models is necessary and one of the goals of the research.
