I have many polygons I'm trying to make a union of. The polygons have a high possibility of shared vertices which causes the "NOTICE: TopologyException: found non-noded intersection between ..." error. How can I avoid this error? I did find a reasonable query that used linework which solved that

Re: [postgis-users] countries with more than one srid ?

Roman, I think you will want to stay away from ellipsoid for now or at least until PostGIS 2.0 (or 1.5 comes out). Those in current PostGIS just deal with point geometries and not terribly well. I think your best bet is to find a spatial ref that covers all of Nigeria. It won't be quite as acc

Ravi, We tend to agree with you on this. Anton, Is there a technical reason why you don't recommend windows aside from the added effort of compiling against windows. E.g. it just doesn't work under windows? We haven't tried it ourselves, but since we will be covering it in our book, we were pl
