I'm having problems reprojecting an ImageMosaic layer from EPSG:6343 to
EPSG:4326. I am using the 2.11.0 war on Ubuntu 16.04 / Tomcat8.
In ArcMap when I reproject the source image with a transformation dx=0.995600
dy=-1.901300 dz=-0.521500 rx=0.025915 ry=0.009426, s=0.000620, I get a correct
reprojection when comparing to an independent control shapefile.
However, from Geoserver wms I see a shift of between 1 and 4 metres. I saw this
post
http://osgeo-org.1560.x6.nabble.com/custrom-CRS-transformation-parameters-are-still-intact-td5135625.html
and it seems to be similar my issue.
I tried overriding 6343 (adding the above parameters to TOWGS84) as described
in the docs. Using a custom CRS in user_projections/epsg.properties reduced the
shift amount, but is still off by ~1m.
I wasn't sure what the epsg_operations.properties entry should look like, so I
haven't tried that solution.
Has anyone else had this issue? And how were you able to resolve it?
Thanks.
