Yes, it works with the cgi version of mapserver (go here
http://www.fs.fed.us/eng/rsac/baer/jfs.html click on one of the fires). I
did not try the tileindex. Breaking development. After changing to
mapscript 3.6 on Maplab and not using the tileindex, the raster layer is
now rendering, yeah! Here is the layer object that works...
LAYER
NAME "Topo"
STATUS ON
DATA "l48_topo.tif"
TYPE RASTER
#TILEINDEX "lower.shp"
#TILEITEM "lower"
TEMPLATE "ttt.html"
METADATA
"DESCRIPTION" "Topo"
END
END
Here is the one that doesn't
LAYER
NAME "Topo"
STATUS ON
DATA "lower"
TYPE RASTER
TILEINDEX "lower.shp"
TILEITEM "location"
TEMPLATE "ttt.html"
METADATA
"DESCRIPTION" "Elevation/Bathymetry"
END
END
I would like to tile this tiff since it is so big. Am I not providing the
correct attributes to the layer for tileindexing? The tile index points to
only one file at the moment

Not that I know of. The same mapfile works with mapserv cgi?
