Hi Alexander,
Thanks for the response. Yes, I am using a GetCoverage request that
looks like this:
http://localhost/cgi-bin/mapserv?map=/var/www/mapfiles/netCDF/netcdf.map
SERVICE=wcs
VERSION=1.0.0
REQUEST=GetCoverage
COVERAGE=elev
CRS=EPSG:4326
BBOX=125,50,130,55
WIDTH=600
HEIGHT=600
Sorry for the spam, I think I found the answer. Both RESX and RESY
need to be positive values. Using that, I am able to get back data
that matches the original data.
Thanks,
Roger

Sure thing. Here are the OUTPUTFORMAT declarations I have:

You're right, 1/2 pixel offset is definitely present. What a pain.
Any idea when the 5.4 stable release is expected? I see that a beta
release is available currently.

This is the ticket I found relevant to the issue:
Are you seeing the issue with both WCS 1.0 and WCS 1.1? I could have
sworn I fixed WCS 1.0 back at the 5.0 but
perhaps the merge of the WCS 1.1 support broke that. There is code in
mapwcs.c to account for the differences in
various pixel models (MapServer, WCS 1.0 and WCS 1.1).

Hi Steve,
You're right. Version 1.0.0 requests don't show a 1/2 pixel offset
when overlaid on a static data image, version 1.1.0 does. However,
once they're overlaid, I do see a difference in data values. I'm
going to have to figure that one out next.

Sorry for the hassles. Changing the pixel model between versions is a
pain. Now MapServer matches WCS 1.0 and GDAL matches WCS 1.1 I believe.
