MGRS Decoded

MGRS encodes location as a nested hierarchy — zone, band, grid square, and offsets. Here is what each component of 31NDH3267004178 means.

Component Value Meaning
UTM Zone 31 One of 60 vertical slices of Earth (6° wide each). Zone 31 runs 0° to 6° longitude.
Latitude Band N One of 20 horizontal bands (8° tall each), lettered C–X (skipping I and O). Indicates the general latitude region.
100 km Square DH A 100 × 100 km grid square within the zone/band. Column letter D (west–east) and row letter H (south–north).
Easting 32670 Distance east within the 100 km square. 5-digit value = 10 m resolution. Multiply by 1 to get meters.
Northing 04178 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 Porto-Novo's geohash at every precision level alongside the bounding box each level represents.
