I wanted to find the distance from a point (lat 36N long 12E) to all the polygons in my shapefile. People on this forum helped me out and said that I should create an "XY layer" with only that point, and then use the 'spatial join' tool to find the distance from the polygons to the point.
When I use 'spatial join' it says that the "XY layer" I created doesn't have a defined projection. So I tried to define the projection, but no matter which Coordinate System I try, it fails to do so. (My polygon shapefile is defined under the GCS_WGS_1984 coordinate system).
I'm new to ArcGIS and am using ArcMap 10.1.
