Underpass

Underpass updates a local copy of the OSM database in near real-time. It is designed to be high performance on modest hardware.

Getting started

Build

./autogen.sh && \
  mkdir build && cd build && \ 
  ../configure && make -j$(nproc) && sudo make install

Setup DB

1. Import setup/db/underpass.sql to a PostGIS database
2. Download a OSM OBF file, ex: wget https://download.geofabrik.de/south-america/uruguay-latest.osm.pbf
3. Import it underpass -i uruguay-latest.osm.pbf
4. Create indexes importing setup/db/indexes.sql the DB

Setup priority area

If you already have a GeoJSON, skip steps 1 and 2.

1. Download a poly file, ex: wget https://download.geofabrik.de/south-america/uruguay.poly
2. Convert it to GeoJSON, ex: python utils/poly2geojson.py uruguay.poly
3. Copy priority file, ex: cp uruguay.poly /usr/local/etc/underpass/priority.geojson

Run

underpass -u <OSM Planet path, ex: 006/390/702>
