All,
I have an image mosaic that looks fine unprojected, but when I project it
the quality is unacceptably degraded.
I have defined my own projection (EPSG:102643).
The mosaic data are stroed in EPSG:102643.
I am trying to project to EPSG:4326.
I have double checked the following
- projection parms
- properties file
I have had similar problems before:

Here is the mosaic:

Thanks in advance.
Paul

Paul, I've looked into your use case and I can confirm something very
bad is going on, but I don't exactly know what... the issue is hidden
deeply in the coverage reprojection code.
In the meantime I've opened a jira issue with all the information
needed for the coverage developers to reproduce the issue. You may
want to "watch" the issue so that you'll be notified when any progress
is made:
http://jira.codehaus.org/browse/GEOS-1720
Cheers
