Geo-Object Librarian (GOL)

• Build and manage Geo-Object Libraries (GeoDesk's compact database format for OpenStreetMap features).

• Run GOQL queries and export results in multiple formats.

gol is a single self-contained executable. Simply download and unzip.

First, build a GOL from OpenStreetMap data:

gol build france france-latest.osm.pbf  
# produces france.gol

Extract the boundary of Paris as GeoJSON:

gol query france a[boundary=administrative][admin_level=6][name=Paris] > paris.geojson

Display the museums of Paris on a map:

gol map france red: na[tourism=museum] -a paris.geojson

Get the names and phone numbers of all restaurants in France:

gol query france na[amenity=restaurant] -f csv -k name,phone
