Dear Francois: I ran your coordinates through the mapblaster program and determined that indeed they are for the location of City Hall, downtown. I didn't check other cities, though. In the mapblaster program there is an option similar to your's for which you give mapblaster the name of the city that you want and it gives you a city map with its coordinates. For some reason, the coordinates that mapblaster gives for Tucson are precicely for the entrance gate to Davis Monthan Air Force Base which is several miles from City Hall on the outskirts of Tucson!
Thanks so much for getting back to me with your answer, and please excuse my mistake in confusing your program with Fer's.
