GeoDjango GeometryZ Field Wanted.

[Thomas Steen Rasmussen]

Hello,

I have a dataset which makes use of a postgis field of type geometry(geometryz, 25832) ​https://github.com/tykling/django-dawa/blob/master/docs/schema.sql#L92

The field type uses the geos name "GEOMETRYZ".

Any chance of getting support for this field type in GeoDjango? I've gotten as far locally as getting the field type added to ​https://github.com/django/django/blob/master/django/contrib/gis/db/models/fields.py and ​https://github.com/django/django/blob/master/django/contrib/gis/forms/fields.py so I have a model with a GeometryZField which generates the correct CREATE TABLE SQL from the migration. It was just a few lines of code, but I am not sure what else is needed to add support for geometryz?

Thank you!

I don't see a wide usage of GeometryZ, it's a Geometry but limited to three-dimensional coordinate space. Please take into account that Django supports only 3D (XYZ) coordinates so you should be able to use GEOSGeometry instead.
