Bug

Projecting a point in a custom geoprocessing service from NAD_1983_HARN_UTM_Zone_18N to NAD_1983_StatePlane_Maryland_FIPS_1900_Feet suffers from a 3 feet precision error in the Northing coordinate.

Zusätzliche Informationen

The behavior is expected. As it is possible that gtdefalts.json file is used to get the default transformation. If the transformation 108190 is used then 1 meter offset is expected. The transformation that should be used is NAD_1983_To_HARN_MD_DE, 1485, which has a smaller offset between NAD83 and HARN (cm-level) - user needs to specify it. The service is using gtdefaults.json file, and in this case, it's the wrong answer.
