OGR/GDAL threading results in low core utilization @lynxlynxlynx - yep. Memory is definitely not the bottleneck. Been trying to track this thing down all day... this is pretty weird. |

Area units for GEOS area property? @whuber - how are you determining the "correct" area of the polygon? Are you using the local projection for NY? I'm trying to be able to do this across the world - is there generally a good way to do this? I'm surprised that the PostGIS ST_Area function isn't more accurate... |

Area units for GEOS area property? The area property of a GEOS object is a float (not an Area object), or at least that's what I'm seeing (so you can't call .sq_m). |

Area units for GEOS area property? and @whuber - thanks for your quick replies! Like scw suggested, I tried the geography field approach (although I would have preferred to avoid creating additional models in the database) like this: class DummyBounds(models.Model):
bounds = models.MultiPolygonField(geography=True)
objects = models.GeoManager()
In my code I write:
db = DummyBounds(bounds=polygon)
sq_meter_area = db.bounds.area
print sq_meter_area
And it appears that my "sq_meter_area" variable is actually still in square degrees (I get 0.000386078620723). Am I doing something wrong? |
