Hi Frank,
This may work, but I'm unable to test it, since I'm currently unable to
retrieve anything newer than 5.2.1 (included in the latest ms4w.zip).
There's a newer version 5.7beta of Mapserver included in the FWTools
package, but the DLL set it uses seems totally different from the one
used in cgi-bin in the ms4w package.
Please advise as to how I can download a newer version of Mapserver.
Cheers.
Best regards / Med venlig hilsen

Hi,
I'm trying to set up Mapserver as a WMS server, serving multiple
seamless coverages consisting of ECW raster tiles.
My problem is, that the ECW files have been delivered with faulty
header information, and there's too many to fix manually, and the
error cannot easily be remedied programmatically.
However, I have generated TFW files for each tile that are correct,
but how do I force Mapserver to use the TFW files and disregard the
faulty ECW header ?
Lars,
As it happens this is not a unique situation and MapServer itself has
some
logic to address it. If you add:
PROCESSING "EXTENT_PRIORITY=WORLD"
to your layer definition, then world files will be searched for in
preference
to using the georeferencing returned by GDAL. I'm not sure exactly
when this
was incorporated but I imagine it is in 5.4 and later. Also the file
extension
should likely be either .eww or .wld, not .tfw for ecw files.
Best regards,
