Command

This class extends the database inspection functionality to provide specialized support for geographic information systems (GIS). It overrides field type detection to identify specific geometry types and spatial parameters from the database backend during the introspection process. This ensures that spatial columns are correctly mapped to their corresponding geometry field types rather than a generic geometry field.

Attributes

Attribute	Type	Description
db_module	string = django.contrib.gis.db	The Python path to the database module used for spatial database introspection.
