I don't pretend to be an expert on this subject although we certainly do have experts at Esri. Anyways, it's been explained to me that the exact datum transformation depends on the geography of the source data, as well as the exact time. The datum conversion I offered was given to me as the most g

Hi Carl, Adding "VPATH" support for the autoconf setup has been on my wish list of things to have in the current build system. It will take a bit of patching. And hasn't made it up to the top of my priority list (and won't for a while) So the answer is: Not yet. If anyone wants to take a stab

Hi Maning, For NAD83 you need to convert the Datum to WGS84. The WKT string you show does not include that conversion. Proj.4 is missing these in a lot of cases. Try this string instead: PROJCS["NAD83_California_zone_5_ftUS",GEOGCS["GCS_North_American_1983",DATUM["D_North_American_1983",SPHEROID
