So gdalinfo with Upper Left ( 0.0, 0.0) etc. means that gdal cannot get the correct georeferencing for your images. They are placed at coordinates (0,0) instead and then the WMS BBOX does not intersect the image area and server is sending a white map for you. And "ERROR 1: Maximum number of characters allowed reached." suggests that for some part of the system the file path is too long. I have never seen such an error but I would still take it seriously and have a try placing the images into a a place like /mnt/pathtest/image_01.ecw

Hi,
Could you send also a gdalinfo report about one of the your .ecw images?

Thank you for your reply Jukka
I tried but still dont work. My raster is ecw file with an .xml file for the spatial reference specification. I try to add a .wld extension but no result. If I remove the WMS_EXTENT tag, no raster appears on my map. In my previous message you can see the raster index shapefile. Realy strange !

Hi,
It must come from this new feature, capture from http://mapserver.org/ogc/wms_server.html
"wms_extent
WMS TAG Name: BoundingBox (WMS1.1.1, sect. 6.5.6)
Description: (Optional) Used for the layer’s BoundingBox tag for cases where it is impossible (or very inefficient) for MapServer to probe the data source to figure its extents. The value for this metadata is “minx miny maxx maxy” separated by spaces, with the values in the layer’s projection units. If wms_extent is provided then it has priority and MapServer will NOT try to read the source file’s extents.
For Rasters served through WMS, MapServer can now use the wms_extent metadata parameter to register the image. If a .wld file cannot be found, MapServer will then look for the wms_extent metadata parameter and use the extents of the image and the size of the image for georegistration"
I would first remove the EXTENT from LAYER and wms_extent from layer metadata and see what happens then. You would get a visual hint about what happens by making the tileindex shapefile as a normal vector polygon layer and by showing it above the imagery layer.

> Hi list, I try to migrate a map service to Mapserver 6.0.1 that work perfectly with a Mapserver 5.0.3 and I have a strange behavior with a TILEINDEX layer. If you look the picture(in yellow you have the raster coverage)(http://mapcoop.org/www-demo/bugorthos.JPG), you see that my image coverage is not the same scale? The raster coverage fit exactly with the WMS_EXTENT tag of my TILEINDEX layer. Moreover, if I comment the WMS_EXTENT tag no raster appears in my map. Images are ECW files and projection is EPSG:32187. The GETMAP is EPSG:32198. I had to compile GDAL 1.8.0 to use ECW driver. Did I miss something? Where should I look?
