Tileindex problem

Eros -

You checked the location field, but you didn't tell us what you found
<g>.  As was suggested, this is likely to be a problem in
misunderstanding paths and how relative paths work in MapServer.  If
possible, using absolute paths is a good idea and prevents that sort of
problem.  At least for debugging, try creating your TILEINDEX with
absolute paths in the 'location' field; if that fixes it, you know where
the problem is.

Hi List,

I have a problem in using tileindex

I mean:

if I display a raster file (tiff+tfw) it shows: OK

DATA "IGN_50000/psc_3124.tif"
TYPE RASTER


if I display a group of rasters (including the previous one) with
tileindex: 
Nothing is showed (except the class name in the legend)

TILEINDEX 'IGN_50000/IGN_50000.shp'
TILEITEM 'location'
 TYPE RASTER


I checked the 'location' field in the tileindex file, I checked the
position of raster files, but it seems OK


Any idea?

Thanks a lot

Eros

I use imagemagick and gdal_translate to split and build tiles from large
images. Then I build a tile index with gdaltindex. As long as you tile
index layers MIN/MAX scales are set right you get a pretty big
performance gain. However if you're rendering many of the tiles in the
same image it slows down. I create overviews for large scales and
display those and have the tile index only come on at lower scales.

What kind of programs/scripts do most of you use to tile .tif images?
I'd be interested in playing with this. Do any of you that use tiled
images notice an improvement in performance?
