Jason: when you say create 2 geometry types one with 2 dimensions etc... how do you specify how many dimensions to have? Because I created the field in this way:
geom = models.MultiPolygonField(geography=True, spatial_index=True) and let the Django migration do the job, but I don't know how to specify that it's a 3D field.
