A basic Open-source Carte internationale du Monde au Millionième nomenclature encoder.

Project Description

Pymil is a simple Carte internationale du Monde au Millionième nomenclature coder. You might find it useful for searching maps for a specific coordinate pair. Typical usage would be something like:

#!/usr/bin/env python

import pymil

map = pymil.code(-11, -61) #Currently uses only decimal degrees;
map["100k"] #Returns a list containing the code elements for the 1:100k map that contains the area.
print map #Returns the code for 1:25k by default, in a string

CIM

The CIM uses the geographic coordinate system as background for the Earth separation, each individual chart receives a code that is composed by two letters and a number. The two letters represent respectively the hemisphere (north or south) and a interval of 4° in Earth’s latitude, which follow the alphabetical order starting from the Equator and increasing to the poles. The number represents a interval of 6° in longitude, marked with numbers and starting in the 180° meridian.

The letters that follow this are subdivisions of the basic millionth chart and indicates charts in scales 1 to 500,000, 250,000, 100,000, 50,000 and 25,000. The letter/number used in each part of the code deppends on the relative position of the chart to its smaller scale counterpar.

TODO

  • Make better docs.
  • Extend functionality, maybe letting you use UTM and whatsoever. DMS would be nice and easy, also.

Thanks

  • Luis Urtiga for the CIM nomenclature explanation.
