I have a number of file geodatabases containing feature classes using a specific geographic projection.
I wish to convert them all to feature classes in a replacement file geodatabase having a different
geographic projection (for reasons of efficiency). How can I do this?
None of the tools in the standard ArGIS-10.3.1 toolbox (Data Management Tools => Projections and Transformations) don't seem to support it:
Batch Project only shows files of type "Geographic datasets" and doesn't even display the name of the file geodatabase
Project is for a single dataset only
I have looked at ArcCatalog => Export => To geodatabase (multiple)
but it isn't quite clear to me how to convert the projection.
One can modify the Environments => Output Coordinates
and change the output cooordinate system from "Same as Input" to "As Specified Below"
but it asks for the geographic transformation without providing any guidance
about which one(s) should be used. Batch Project, mentioned above
seems to know which transformation to use since it doesn't ask the user
for that information.
