Graphics Offset from Origin Layer

NathanaelVaughan — Fri, 07 Feb 2014 15:49:10 GMT

I have a simple parcel search function in my viewer. The parcel service is not in the same projection as my map (this may be relevant).

The parcels returned are offset, which looks strange. I've done some searching and not found a solution.

Ideas?

Hi Nathanael,

What are the two coordinate sytems that your map is using? You may need to apply a datum transformation using the ProjectParameters class.

The viewer projection is: Spatial Reference: 3483

The service projection is: Spatial Reference: 102100 (3857).

I don't expect this to be the problem as the projected features in the map would match the "misprojected" features from the parcel search (see the image in the original post). Unless the projection is handled differently between the two uses.
