However, the biggest issue when two people are using two different coordinate systems is they are often on two separate map datums as well... there is at least one place in AZ where the difference between NAD27 and NAD83 is almost 800m... ask me how I know wink



Okay, I'll bite..

What happened?

I usually use MGRS due to where I get my maps (thanks old USGI buddies).

But as has been mentioned, I also wind up doing conversions. Many cell companies use different systems, but I do work for all of them. I always ensure I can work within all the systems. When we move into an area for work, I contact the local FD, EMS, PD, and Air Ambulance folks. One of the items I get is how they want their directions and GPS info. Cell sites are given addresses, but the address usually has very little to do with where it actually is, and how to get there.
