[Geoserver-users] reprojection behaviour

Attached you can find the 2 images produced by the geoserver and see the difference ...

I only see one image. Besides, image does not tell much, how many meters away are the two? Is this compatible with floating point rounding or not? What program did you use to perform the first reprojection? What if
you use the same program to do the back-reprojection, what would be
the results?

Well the difference is about 300 meters from 4121 to 4326. Which by the way is the difference without the transformation.

away are the two? Is this compatible with floating point rounding or
not? What program did you use to perform the first reprojection? What if
you use the same program to do the back-reprojection, what would be
the results?

The initial transformations done with ERSI products, and the back-reprojection worked fine …
