Hi Ghansham: Are you sure you need Mercator with elliptical earth, and not Transverse Mercator (which uses an elliptical earth) ? If you are sure, we would welcome a contribution from you to add that projection. Best would be if you can do a pull request directly on the github repository. Use the 4.5.3 branch would be best. Thank you, John > I tried to go through the code and actual the issue is related to the fact > that ucar.unidata.geoloc.projection.Mercator assumes eartg shape to be > spherical while I expect it to be ellipsoidal with semi-major and > semi-minor axes. I can add in the proj4 mercator implementation which > allows semi major and minor axes for defining ellipsoidal shape with test > dataset.
