Position Format
The AirMap can show the position in degrees, minutes, and hundredths
of a minute (36° 26.106') or degrees, minutes, and seconds (36° 26' 06.3".
It can also show position in UTM’s or Universal Transverse Mercator pro-
jection.

UTM’s are marked on USGS topographic charts.
This system divides the Earth into 60 zones hori-
zontally, each approximately 6 degrees wide in lon-
gitude. The Earth is then divided into 20 zones
vertically, which are lettered from “C” to “X”. For
example, 15 S means that the position shown to
the right of the “S” is in grid 15 horizontally and “S”
vertically. The numbers to the right of the “S” show
the position in meters from points inside the zone.
