osm_conflate/filter

Filtering OSM by external dataset

When you got points of multiple categories, an Overpass API request may fail from the number of query clauses. For that, you would need to filter the planet file yourself. First, prepare a list of categories and dataset points:

conflate.py profile.py -f points.lst

Then compile the filtering tool:

mkdir build
cmake ..
make

Download a planet file or an extract for the country of import, update it to the minute, and feed it to the filtering tool:

./filter_planet_by_cats points.lst planet-latest.osm.pbf > filtered.osm

This will take an hour or two. The resulting OSM file should be used as an input to the conflation tool:

conflate.py profile.py --osm filtered.osm -c changes.json
