MGRS Decoded

MGRS encodes location as a nested hierarchy — zone, band, grid square, and offsets. Here is what each component of 13SFA7831789168 means.

Component Value Meaning
UTM Zone 13 One of 60 vertical slices of Earth (6° wide each). Zone 13 runs -108° to -102° longitude.
Latitude Band S One of 20 horizontal bands (8° tall each), lettered C–X (skipping I and O). Indicates the general latitude region.
100 km Square FA A 100 × 100 km grid square within the zone/band. Column letter F (west–east) and row letter A (south–north).
Easting 78317 Distance east within the 100 km square. 5-digit value = 10 m resolution. Multiply by 1 to get meters.
Northing 89168 Distance north within the 100 km square. Same resolution as easting (10 m).

Geohash Precision

A geohash encodes coordinates by subdividing the Earth into progressively smaller cells. Each extra character roughly halves the cell area. The table below shows Black Mesa's geohash at every precision level alongside the bounding box each level represents.
