shapefile polygon opens in arcgis but not mapserver

Hi Gerard,

I would suggest using ogrtindex instead to build the tileindexes. There is
a little trick that you should not run ogrtindex from the directory which
contains the data (otherwise it does not create an absolute path to the
data in the LOCATION item). So run it from the directory where you
installed FWTools eg:

for %i in (d:\data\*.shp) do d:\programs\fwtools\bin\ogrtindex
mytileindex.shp %i

About the performance, have you created shapefile qix indexes (using
shptree?). Also, it depends on the GDAL/OGR version whether or not the qix
files are actually used (that's a relatively new feature). If I recall
correctly that was added in GDAL/OGR 1.2.6, but Frank knows for sure.

I think Mapserver normally scales well with a lot of LAYERs, it may have
to do with your data structures and not the amount of LAYERs.

Best regards,
Bart
