I did the following: from django.contrib.gis.geos import GEOSGeometry, WKTWriter wkt_w = WKTWriter() wkt_w.outdim = 2 # This sets the writer to output 2D WKT polygon = GEOSGeometry(json.dumps(item['geometry'])) # The 3D geometry temp = wkt_w.write(polygon) polygon = GEOSGeometry(temp) # The 3D geometry
Here it is in the docs: https://docs.djangoproject.com/en/1.11/ref/contrib/gis/geos/#django.contrib.gis.geos.WKBWriter.outdim On Monday, 7 March 2016 20:43:05 UTC+2, Jônatas Castro wrote: > > In my project I need to import *shapefiles* and same some geometry. > > Some of these are *MULTIPOLYGON Z* type, but all Z coordinates are > 0-value. > > When I try to save the geometry, I get the error: *"Geometry has Z > dimension but column does not".* > > *What is the best way to strip the Z dimension?* > > > > My code: > > > > *ds = DataSource(file_path, encoding='ISO-8859-1')layers = ds[0]* > > *#need something HERE to coerce geometry to 2D* > > > *obj=MyModel(geometry=GEOSGeometry(layers[0].geom.hex))* > *obj.save()* > > -- You received this message because you are subscribed to the Google Groups "Django users" group.
