RE: check out my nifty map!
doughboy, when I got to mapmart.com I click on aerial photography on the top right menu system. Then I click on Begin Search under the U.S. Aerial Photography section. After that you have your map to begin browsing. Then if you click on "Display Coordinates" on the bottom of all the toolbars on the left then the coordinates (longitude/latitude) will be displayed on your mouse when it's on the map. I think that's the closest thing to using the coordinates that I know of.
