replace-invalid-osm-ids
Update invalid (<1) Ids within a OSM file
Editors as JOSM store yet not existing OSM IDs as negatives. However, tools like osm2pgsql or graphhopper do not support such negative IDs.
This script updates all invalid IDs to valid IDs.
Usage
python replace_invalid_osm_ids.py invalid.osm valid.osm
invalid.osm
