Hello All - What is the correct way to cite UTM coordinates for a location in California?
Yikes!  I always thought that for California, there are 2 UTM Zones, 10N and 11N.  I thought this was because N meant north of the equator.  According to Google Earth and ArcMap now, it seems that I should be using "S"?
Ex:  UTM NAD 83 10S 3817233.5N, 755429.3E?
Thank you for any help in putting this to rest once and for all :)
