The first change was to add some towgs parameters, which you could find in my map file, later there was a revision to the ones you are showing in your definition. Between this two towgs flags there isn't much difference or almost no difference in a final map. But if you leave out the flags at all, you will get errors in your spatial position of a few hundred meters.</div><div><br></div><div>No matter what I set in the epsg file or in the map file as projection parameter of the source data set, MapServer is calculating in the DescribeCoverage an extent that matches very close the values that would have been given back by the old erroneous epsg (the one without towgs flags) definition. You can check that with the online calculator tool quite easily if you try to convert the bounding boxes.</div><div><br></div><div>For me it seems that the projection parameters are read from somewhere else in the system where an old definition is present...</div><div><br></div><div>cheers,</div><div>Christian</div><div><br></div><div>BTW: setting wcs_extent didn't help...</div><div><br></div><div><br></div><div><br><div apple-content-edited="true">
