ForeFlight Mobile supports the Military Grid Reference Systems (MGRS), which is an alpha-numeric system for expressing UTM/UPS coordinates.
Formatting
MGRS coordinates can be input into ForeFlight using the following format:
MGRS@NNLSSeeeennnn
The formatting of MGRS coordinates is as follows:
- NN: UTM zone number (6° wide) with leading zero included.
- L: Latitude band (see table below for reference).
- SS: 100,000-meter grid square within the zone.
- eeee and nnnn: Easting and Northing values within the 100,000-meter grid square.
Examples
Examples of MGRS coordinate formatting are as follows:
Example 1: MGRS@15RTP:
- 15: UTM zone number
- R: Latitude band
- TP: 100,000-meter grid square
Example 2: MGRS@15RTN50008000:
- 15: UTM zone number
- R: Latitude band
- TN: 100,000-meter grid square
- 5000: Easting within the 100,000-meter grid square.
- 8000: Northing within the 100,000-meter grid square.
