Frequently asked question

Why are projected layers always displayed in an unprojected coordinate system in the Edit Map page?

Last Published: April 25, 2020


The ArcWeb site Edit Map page always displays maps using the GCS_WGS_1984 coordinate system, even when the layers contain projected data. Layers displayed in the Edit Map page indicate that the data file's coordinate system is defined properly.

When creating a custom map service, an end user application can request maps in any coordinate system supported by ArcWeb Services.

See the link in the Related Information section for a list of supported coordinate systems.
