In many cases geometries for places, features and stratigraphic units already exist as research data from various sources and could be used for the data input.
So far I imported them directly in the PostgreSQL PostGIS using sql commands.
It would be very very helpful to have the possibility to import them already in the edit view of our physical things.
Therefore I suggest to start with WKT and then extend this to .shp files in the future.
WKT could be achieved by inserting the string as text and creating the polygon then via PostGIS geometry from WKT
