Despite the fact that the nad83 and wgs84 datums are supposedly identical, there are several ways to get from one to the other and they result in different placement.
- ESRI recommends this transformation: WGS_1984_(ITRF00)_To_NAD_1983
- FME appears to use this one: nad_1983_to_wgs_1984_1
I am using AttributeReprojector on a dataset with several coordinate systems. Is it possible to indicate a specific geographic transformation for nad83 to wgs84 when using this?
Thank you,
