I don't have instructions but I can show you the diff of the commit that added the Robinson projection to GeoTools (and thus GeoServer), attached. Basically: - add a class implementing the math (which normally comes straight from proj, Frank W. allowed us to get the code), possibly try to register all the aliases for the project name in EPSG, ESRI and GeoTiff styles - register the class in META-INF so that GeoTools knows it exists - add a test to check the reprojection results are the expected ones comparing with the ones of a third party tool, typically cs2cs - if you want to contribute the changes back, so that they will be available in future GeoTools/GeoServer releases, add a patch to jira.codehaus.org for the geotools project, referencing module Cheers Andrea -- ------------------------------------------------------- Ing.
