World Helipads

This project contains a couple of scripts to extract helipads from OpenStreetMap and OpenAIP and convert them to a format that can be used in other tools (for example LittleNavMap).

Thanks to the OpenStreetMap contributors and OpenAIP (under Attribution-NonCommercial 4.0 International license).

Data is extracted from OpenStreetMap using Overpass API and from OpenAIP using OpenAIP Data Exports.

Usage

This project uses Python and Poetry to manage dependencies and virtual environments. To install dependencies, run:

poetry install

To retrieve the data, run:

poetry run python 01_retrieve_data.py

To convert the data into an intermediate format and perform some filtering and deduplication, run:

poetry run python 02_filter_and_merge.py

To convert the data to a format that can be used in LittleNavMap, run:

poetry run python 04_export_lnm.py

Your will find the data in the data/export folder split into three regions. You can import the files as userpoints in LittleNavMap by using the Userpoints -> Import CSV ... menu.
