Maidenhead <-> Lat/Lon

maidenhead provides a simple, yet effective location hashing algorithm. Maidenhead allows global location precision down to 750m

Maidenhead provides 4 levels of increasing accuracy

Level	Precision
1	World
2	Regional
3	Metropolis
4	City

pip install maidenhead

or for development version

git clone https://github.com/space-physics/maidenhead

pip install -e maidenhead

Examples assume first doing

import maidenhead as mh

Lat, lon to Maidenhead locator:

mh.to_maiden(lat, lon, level)

returns a char (len = lvl*2)

Maidenhead locator to lat lon:

mh.to_location('AB01cd')

takes Maidenhead location string and returns top-left lat, lon of Maidenhead grid square.

The center=True option outputs lat lon of the center of provided maidenhead grid square, instead of the default southwest corner.

Command Line

The command line interface takes either decimal degrees for "latitude longitude" or the Maidenhead locator string:

python -m maidenhead 65.0 -148.0

BP65aa

python -m maidenhead BP65aa12

65.0083 -147.9917

The "python -m" CLI is also available:

python -m maidenhead 65.0 -148.0

The --center option outputs lat lon of the center of provided maidenhead grid square, instead of the default southwest corner.
