I was wondering how can I export all the roads (car drivable ones) of USA from OSM? To export it with the website I need to specify some boundaries, but I need only USA's road (and obviously USA's border is not a rectangle). The same is when I try to export it from QGIS's using OpenLayers plugin and also with overpass-turbo. My final goal is to import it into POSTGIS or QGIS. I am sure this is something trivial, but I am new to OSM and can't figure it out. Thanks! |

For such a large region you should download an extract and filter out the roads: http://wiki.openstreetmap.org/wiki/Planet.osm#Regional_extract_sources There are a variety of OSM specific tools that can do this filtering as they load data into a database: http://wiki.openstreetmap.org/wiki/Databases_and_data_access_APIs ... and see https://wiki.openstreetmap.org/wiki/Osmfilter for its features.

Hi You can download the Shape files from the following link and then extract only the roads. thanks mmahmud, but how can I merge them after? Or it doesn't make sense to merge them because of the size?

Sorry, merging with what? What is the ultimate goal here? And did the extraction work?
