Hi (Jeff),
I recently performed updates to matplotlib and basemap.
From this time, I have a random and reccurent error when I create a
Basemap instance.
Here is one example :
from mpl_toolkits.basemap import Basemap
Basemap(**{'lon_0': -4.5250263598141309, 'urcrnrlat': 49.140154231678416, 'projection': 'cyl', 'llcrnrlon': -7.2999968048710144, 'lat_ts': 47.468781818043126, 'urcrnrlon': -1.7500559147572474, 'area_thresh': 0.1, 'llcrnrlat': 45.797409404407844, 'resolution': 'i', 'lat_0': 47.468781818043126})
GEOS_ERROR: TopologyException: found non-noded intersection between
8.67583 4.66292, 8.70206 4.66997 and 8.71039 4.67664, 8.67708 4.64997
8.70205 4.66997
It depends on the area and the resolution (polygons).
I have version '0.99.3' of basemap.
Any idea?

Stephane: I'd say it's an issue with your geos library installation that basemap is linking to. I don't see that error using your example for geos 2.2.3 or geos 3.0.3.
I'd suggest rebuilding the geos library, then recompiling basemap.

Yep, the same library (physical, on our network) fails depending only
the computer, thus on its own internal libraries called by GEOS.
By the way, I tried basemap with geos 3.0.4, and saw the "simplify()"
method working. That's funny!
