Schematisation objects
======================

A Rana 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 Rana schematisation 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 :ref:`schema_300` for more information.
