I have a feature class with UTM X,Y coordinates. I have defined the projection as UTM, however when it is added to ArcMap it plots as if the coordinate values are decimal degrees. I AM NOT A COMPLETE NOOB, although not a career expert and could be missing something easy. I am open to suggested solutions in the ArcMap window or with ArcPy. I have attached screenshots as proof that I am not crazy. I have tried defining the projection multiple times to no avail. I tried to project it into WGS 84 degree coordinates, but the numbers of the extent didn't even change it just changed the "m" after the values for meters to "dd" but the numbers remained the same. I have other layers in the map file that are properly plotted in WGS 84 spherical coordinates. The only thing I can think of to try is to manually convert each X,Y value to it's corresponding spherical coordinate but that's a lot of trigonometry, so someone please help.
