Generalization of 2D and 3D Data

Generalisation is a process to transform spatial data from a detailed scale into a less detailed scale. Unlike the geometric simplification, generalisation does not only decrease the complexity and data volume, but also improves the cognitive perceptibility of spatial situations for cartographic presentations. This is comparable to how maps work. If we want to draw the attention of a user to a specific building, we can visualise its surrounding area with generalised models, whereas the important building is presented in its original or even highlighted shape.
