I publish hosted feature services from an arcmap document that are in the NAD_1983_StatePlane_South_Carolina_FIPS_3900_Feet_Intl coordinate system. When they come into the webmap that they are used in, they shift into WGS 1984. Periodically I export and download them as FGDB, and then use these data to bring back into our SDE, which is in the NAD 1983 State Plane Coordinate System. When i see the downloaded fgdb in arc catalog it says that it is in the NAD 1983 State Plane. How can i trust that this is true? Is there a way to verify that the conversion from WGS 1984 to NAD 1983 State Plane is successful?
