Install

pip install maidenhead

or for development version

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

pip install -e maidenhead

Examples

All 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:

maidenhead 65.0 -148.0

BP65aa

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.

Alternatives

We also have Maidenhead conversion for Julia.

Open Location Codes a.k.a Plus Codes are in Python code by Google.
