I have a geoserver that displays some basic country data for Brazil at a course spatial scale (1:1 milion). Now the geography institute (IBGE) is making available the topo sheets at 1:250,000 scale, one shape file for each of the 548 tiles. My question is: In order to store those data in PostGIS and serve via Geoserver, would I be better of merging all topo sheets into one? Or is it better to have each sheet as a separate table in PostGIS? This, of course, considering that there will be no topology issues with the sheets.
