title: How to create osm.pbf file?
body: <p>I am working on a offline routing app for a particular region which will use graphhopper library for android. I want to know is there any way to create osm.pbf file for a region instead of downloading the file for the whole country.
  Moreover is it possible to create .map file for a particular region ?</p>
  
  <p>Thanks.</p>
