Hi Pierre: Version 0.9.6.1 didn't use the GEOS library. Your example works for me with geos 2.2.3, so I suspect you're using geos 3? I've found that geos version 3 is a bit buggy, and chokes on coastline polygons that geos 2.2.3 handles perfectly well. I have geos 3 installed at home, so I'll try your example when I get home today and see if I can find a workaround. > _____ > use_new = False > if use_new: > from mpl_toolkits.basemap import Basemap > else: > from matplotlib.toolkits.basemap import Basemap > (llcrnrlon, llcrnrlat, urcrnrlon, urcrnrlat) = (-86.50, 30.50,-80.00, 35.01) > for resolution in (None,'l','i','h'): > basemap = Basemap(projection='aea', > llcrnrlon=llcrnrlon,llcrnrlat=llcrnrlat, > urcrnrlon=urcrnrlon,urcrnrlat=urcrnrlat, > lat_1=29.5,lat_2=45.5,lat_0=23,lon_0=-96, > resolution=resolution) > print 'resol',resolution > _____ > > > As a side note, would it be possible for the config script to search whether > GEOS is installed in /usr ? > Done (r6357). -Jeff > Any suggestion/cooment welcome, > Thanks a lot in advance > P. > > ------------------------------------------------------------------------- > This SF.Net email is sponsored by the Moblin Your Move Developer's challenge > Build the coolest Linux based applications with Moblin SDK & win great prizes > Grand prize is a trip for two to an Open Source event anywhere in the world > http://moblin-contest.org/redirect.php?banner_id=100&url=/ > _______________________________________________ > Matplotlib-devel mailing list > Matplotlib-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/matplotlib-devel > -- Jeffrey S.
