I have an Excel table of points with X,Y coordinates.
I imported it into ArcMap and created a feature class and then a map. All fine.
Now I want to update the map by adding one more point, whose X,Y coordinates I have.
But I don't want to re-import from Excel because that will create a NEW feature class, and I like the one I have and how it looks on the map (symbology, labels...). I don't want to have to re-do all that.
Isn't there some way to add this one new feature to the existing feature class' attribute table? Of course, ArcMap would have to digest the X,Y coordinates that I typed in. How?
