[postgis-users] Build topology for polygon layer using postgis2.0

[Elton Chan]

Hi there,

I would like to build topology for a polygon layer using postgis 2.0. The polygon layer contains contiguous polygons snap to each another but some are having some geometry error such as gap is found between polygons.

Does anybody know the procedure to build topology with abovemention polygon data? More precisely, any procedure to convert all the polygons to line strings, then remove duplicate lines, and build topology and remove
small polygons.

Thanks,
elton
