[mapserver-users] Layer with over 6000 shapefiles

[EVANS, JAMES R GS-13 USAF ACC 84 RADES/SCZE]

The Tile4ms utility is kicking out an error on some of the larger shape
files, saying the .dbf doesn't match the file.  Whatever that means.  I can
still load the "bad" shapefiles in Global Mapper, and they appear to be
correct.  I'm reprocessing the data now to cut down on the number of files.
I should end up with a 48x16 grid covering the whole world.  Hopefully I can
get that working with an index and speed things up when displaying this
layer.

I've created a set of contour files for the whole world, and when I had the
info in a single shapefile it was about 260GBs.  Mapserver would serve it
up, but performance was horrible.  I now have the set broken up into about
6000 separate shapefiles, but don't know how to address that in a single
layer.  I tried using gdaltindex, to create a single index file that points
to all the other shapefiles, but I get an error saying the shapefiles are an
unsupported type.  Is there some other way to create an index that Mapserver
can use to point to this many shapefiles?

Check the results from tile4ms with shpdump and make sure that you dont have
all null shapes. I have run into this on Ubuntu. I believe in both the
packages and compiling for source. I haven't had time to run down what the
issues are.
