When no transformation is found in ArcGIS Field Maps when adding a location profile, and GPS averaging is enabled, field map transforms the data to WGS 1984 rather than applying no transformation as it does with single points.

対処法

Using GCS:North American Datum of 1983 (CSRS) EPSG:4617 in ArcGIS Field Maps for the incoming GNSS positions (not GCS:NAD83 CSRSv7 (EPSG:8255)), and use PCS:NAD1983 CSRS UTM Zone 17N (EPSG:2958) for the basemap and destination feature class since they both use the same GCS. The client's destination feature class has a custom projection defined, but the CRS of the data frame for the service is PCS:NAD1983 CSRS UTM Zone 17N (EPSG:2958). Since the positions do not need to be transformed, it gets passed along as is, which is what is wanted.
