3D GRB

The 3D GRB is a 3D model of available Large-Scale Reference File (GRB) objects that allows to visualize these GRB objects in 3D and to efficiently query height information per GRB object. The height information comes from the source data of the Digital Height Model Flanders (DHMV) and can be extracted from both the DHMV I and the DHMV II depending on the product entity. The appearance of the 3D GRB also depends on the level of detail or the LOD level (level of detail).
