testdata-generator

When writing tools that process OpenStreetMap data, it usally useful to have realistic testing data. testdata-generator is a utility to generate synthetic (or random) OpenStreetMap data in XML format.

In particular, this data will not contain any private data that may be subject to the GDPR. It will neither be restricted by the ODbL.

Notes

• At the moment, the output contains only nodes (no ways, and no relations).
• The output format mimics historical data dumps (the output XML file may contain multiple revisions for each node).
• For further details about the OSM XML format, see the osm wiki.
