Dane, How would I reproject the builtup_areas shape file? The current projection is listed as &srsmercator (<!ENTITY srsmercator "+proj=merc +datum=WGS84 +over">) unlike the other 2 projections for the shape files which include the epsg code within its variable name: &srs900913 and &srs4326.
I use ogr2ogr to reproject the shape files but I need to know the current epsg code in order to reproject.
