This software is designed to support PostGIS/Imposm-based workflows for conflation of third-party data with OSM. The resulting changefiles can be used post-conflation to enable the updating of the source Planet file (or any other extract) with newly-conflated data via software such as [Osmosis](https://wiki.openstreetmap.org/wiki/Osmosis).\n\nThe primary output of this software are `.osc` files, described in detail [here](https://wiki.openstreetmap.org/wiki/OsmChange). (_It is important to note that `.osc` change files are distinct from [OSM Change Sets](https://wiki.openstreetmap.org/wiki/Changeset)_)\n\nMain Features:\n\n- Ensures properly noded junctions (e.g. intersecting Ways always share a Node).\n- Preserves topology of existing OSM network.\n- Configurable ID generation (negative IDs, arbitrary offsets)\n- Use of GDAL for efficient geodata processing\n\nThis software is currently in an alpha release, and will change rapidly.\n\n## Contributing\n\nWe welcome pull requests for consideration.
