ECW Quality for WCS download

[Eijnden, B. van den (Bart)]

Hi Gail,
 
what kind of requests are you trying? Could you supply an example URL?
 
In the URL you can specify res_x and res_y and if you give those the same
value as your source data you should get the same quality, at least for us
it seems to work fine like that. We also output to MrSID, ECW and Geotiff
using Mapserver WCS.
 
Best regards,
Bart

Dear MapServer users,

 

I would like to provide ECW format radar data for download via a WCS (aswell
as Geotiff format). I have managed to get the ECW images to download via WCS
but the quality of the image has been reduced greatly when I compare to the
original image on the server. What could be the reason for this? I would
appreciate any suggestions.

The quality of the GeoTiff's in comparison is the same as the image of the
server, does GDAL work for ECW WCS?
