Schematisation objects

A 3Di schematisation consists of rasters, vector layers and settings. This section describes these schematisation objects, their attributes and requirements.

Note

In March 2025, a completely new 3Di database schema was introduced, which means that the names of many layers and their attributes have changed. If you were used to the old database schema, see Database schema 300 for more information.
