A few ESRI ids correspond to ESRI authid codes - but not all so it's not fool-proof...
Assuming the esri code DOES correspond to EPSG code, you would basically use OSRImportFromEPSG( <latestWkid>) In your example, the "latestWkid" : 3857 corresponds to EPSG:3857 which is the WGS 84 / Pseudo-Mercator and "wkid" : 102100 is the "old" id which has been replaced by 3857 see: http://forums.esri.com/Thread.asp?c=93&f=984&t=288607 http://forums.arcgis.com/threads/8762-WGS-1984-Web-Mercator-(Auxiliary-Sphere)-WKID-102100 Frank - this may require yet another ESRI-OGC translation scheme! Many (but by all means not all) ESRI srid correspond to EPSG authids, but not in the upper range....
