About this dataset
Postal Codes Dataset for Martinique (MQ)
This dataset lists the postal codes of Martinique with place names, WGS84 coordinates, administrative divisions and alternative city names.
Column definitions, row count, size and last-updated date are in datapackage.yaml.
Data Sources
- Postal codes, place names, administrative divisions and coordinates: © GeoNames, postal code export for Martinique, CC BY 4.0.
- Alternative city names: the GeoNames gazetteer for Martinique, same licence.
Changes made to the source data: place names and administrative division names cleaned (a parenthesised part is dropped, punctuation becomes a space and repeated spaces collapse), and an alternative city name added from the gazetteer where one matches the place name.
Not endorsed by, or affiliated with, GeoNames.

The dataset files are available in CSV format and can be accessed and downloaded using
the links provided in datapackage.yaml.
