cull osm.pbf #4

Closed AdrianKriger closed 2 years ago

AdrianKriger commented 2 years ago

I'm starting with a city-level osm.pbf -> available from either Geofrabik and BBBike via pyrosm

It might be helpful to iteratively trim the osm.pbf before the focus area is selected and buildings are harvested. Here osmfilter or osmconvert with poly files could do the necessary.

This will generalize the solution to country-level osm.pbf's

A few timing tests: a) country.pbf -> focus area; ~ too long b) country.pbf -> region -> focus area ~ 5 min. ~ trim + full run would make for an evidence based decision.
