We recently transitioned from from ArcGIS StreetMap Premium Standard to Custom Roads which resulted in a change to the coordinate system:
- Standard (.gdb😞 GCS_WGS_1984 Geographic Coordinate System using D_WGS_1984 datum
- Custom Roads (.gdb😞 WGS84 Web Mercator (Auxiliary Sphere)
We have systems that make calls to this rest endpoint and expects the results to be in GCS_WGS_1984. These systems cannot be modified to change the parameters of the request. (example outSR=4326). Dataset restrictions would not allow us to modify the underlying network dataset to accommodate these systems. Our workaround was to use IIS URL rewrite rules to default the output spatial reference. I believe it would be beneficial to specify a default output spatial reference during time of publishing or afterwards in ArcGIS Server Manager under the webservice's Select and configure capabilities.
