From the image below, you can label a maps corners based on an existing Measure Grid, but this label indicates not the corner position, but the grid line closest to that edge. [ATTACH]5458[/ATTACH]
Using either a Measured Grid(in X,Y) or a Graticule (lat,lon / dd / dms) what are some of the options in ArcGIS 9 and above that would allow you to do this easily or automatically?
My current workflow: Create extent polygon > Convert to points > Create two new x/y fields and calculate geometry > use those fields in a label expression > optional - copy and paste to graphic element
