Geodetic Models

Geodetic Data

Geodetic or geospatial data are composed of point, lines and area relations. These data are rich with attributes. As in many other sciences, geodetic problems are located in a real world.

The concept – the problem need to be modeled.

The Solution – have to be put in a geometrical and physical formulation by mathematical means

The purpose is either description or explanation and allow to

i) estimate non-observable state and

ii) predict future state

Typical types of models in geodesy are:-

i) Measurement model (observation model)

ii) Geodetic model (theoretical model)

Both models are connected via the geodetic observable.

The task of measurement – to correct and evaluate the raw observation (true observation) to adapt them to the geodetic model
