[mapserver-users] problem with raster data..

[Stephen Woodbridge]

The tileindex is used in a layer like you have shown below.
Your map image is "built-up" from the layers in the mapfile. The first 
layers are drawn into the output image first and so on through the 
mapfile. So if you want your images to be the background of the image 
then put that layer first in the mapfile and all other layers will be 
drawn on top of that.

Also for directory paths, I think it is best if you lay them out 
something like:

/path/to/data/
/path/to/data/nztm/...

then:

cd /path/to/data/
gdaltindex 250k_index.shp nztm/250Kfiles/*.tif
shptree 250k_index.shp

adjust the paths as appropriate. Then in your mapfile

DATAPATH "/path/to/data"

...
LAYER
   ...
   TILEINDEX "250k_index"

basically start out putting all your tileindexes in /path/to/data and 
putting all your data in sub directories. This is a simple setup and 
should always work, so start like this. Then you can experiment with 
moving directories and tileindexes around. The reason for this is that 
the rules for how mapserver finds files is not always obvious and 
sometimes requires reading the code or a little simple experimentation 
to get it right.
