41001 no longer has any meanng, but what we meant by it at the time is what we now call 900913. For a time, this was EPSG:3785; this is now EPSG:3857. All 4 of those (and occasionally 54004) mean essentially the same thing in common usage. > > http://trac.osgeo.org/gdal/wiki/SoCGDAL2Tiles#NewsuggestionsforTMSStandard > > <http://trac.osgeo.org/gdal/wiki/SoCGDAL2Tiles#NewsuggestionsforTMSStandard>If > it is the same, maybe it would be a good idea to change the code for EPSG > (update the spec), for a matter of inter operability and compatibility with > other services? > If it is not the same, I would really appreciate if you could point me to > other places where I can get more information about this SRS. > Thanks in > advance, > > best regards, > > Jo > -- > "#define QUESTION ((bb) || !(bb))" (Shakespeare) > _______________________________________________ > Discuss mailing list > Discuss@lists.osgeo.org > http://lists.osgeo.org/mailman/listinfo/discuss -- Christopher Schmidt Web Developer _______________________________________________ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
