ERROR 000365: Invalid geographic transformation.

Hello!

I'm working on a python script tool that will reproject a feature class. I am able to reproject using the Project tool under the Data Management toolbox using the "NAD_1983_To_WGS_1984_1" transformation; however, when I go to run my script using the same transformation method (see below), I receive the error message, "Invalid geographic transformation". Has anyone else run into this problem?

outCS = "C:\Program Files\ArcGIS\Desktop10.0\Coordinate Systems\Projected Coordinate Systems\State Plane\NAD 1983 HARN (US Feet)\NAD 1983 HARN StatePlane California III FIPS 0403 (US Feet).prj"

transformation = "NAD_1983_To_WGS_1984_1"

arcpy.Project_management(featureForProj, featureProjected, outCS, transformation)

Hi Amy,
You're projecting to a State Plane "HARN" projection. You need to use a "HARN" geographic transformation method.
This is the one I use for WGS84 to NAD83:
NAD_1983_HARN_To_WGS_1984_3

Thanks! I guess I needed to do my research on transformations. Sometimes the GUIs make it too easy. 😮
