The OpenStreetMap project collects an amazing amount of geodata and makes it available to the world for free. But the raw OpenStreetMap data is hard to use. This repository contains scripts to set up a server that processes some OSM data and brings it into a format for easier use.

Currently these scripts can be used to derive

  • Coastline data (in the form of linestrings or land or water polygons for the worlds land masses or oceans).
  • Antarctic icesheet data.

datasets from OSM data.

The icesheet scripts are based on

Public server

A server running this code and offering the results for download to the general public is at .


The scripts are intended to work in the Hetzner Cloud. But it should be possible to port them to other cloud providers.

One server runs all the time as webserver and "master of ceremonies". It will start other servers regularly to update a planet file and do the data processing. The results are then copied back to the master server and are available for download from there.

Setting up a master server
