Convert GeoJSON to OSM XML format

To run, get the fat jar (currently you need to build this yourself) in this repository and then

java -cp geojson2osm-all-0.1.0.jar ch.poole.osm.geojson2osm.Convert -i ...

The created OSM elements get negative ids and the files should be usable in JOSM, Vespucci and any other editor that allow loading OSM data.

Usage

-i,--input <arg>    input GeoJSON file, default: standard in
-o,--output <arg>   output OSM XML file, default: standard out
-u,--upload         generate a JOSM specific attribute that will allow uploading the data

Caveats

• Currently this is just a quick hack.
• It will only convert Point and LineString geometries.
• It will punt on LineString Features with more than 2000 vertices
• OSM way nodes are de-duplicated (this should probably be an option)

All of the above is fixable, it just hasn't been done yet.
