You can do the following things to speed up performance: * create a spatial index on your tileindex shapefile with shptree (also make sure you reference your TILEINDEX in the MAP file without the .shp suffix)
* create overviews in the tiff files using gdaladdo Best regards, Bart -- Bart van den Eijnden OSGIS, Open Source GIS http://www.osgis.nl --------- Oorspronkelijk bericht -------- Van: [EMAIL PROTECTED] Naar: mapserver-users@lists.osgeo.org <mapserver-users@lists.osgeo.org> Onderwerp: RE: [mapserver-users] combine many georeferenced tifs in one layer Datum: 10/03/08 10:51 > Thanks a lot Bart and you too Till! > > I had some troubles with the wildcards (*.tif) since the gdaltindex binary from gdal.org doesn't seem to support them - although it says so in the manual.
