This is just a simple question but I could not find the information in the documentation. If I have an existing pgrouting database table named
routing, can I add additional OpenStreetMap data to this table through the osm2pgrouting software? I have some data in the database for Syria roads and I wanted to add additional road information for Turkey, Jordan, and Lebanon. I was not sure if I can just add these osm files to the existing database table, or if I need to drop and load some large osm file that has all of the countries I want.
Note that I did try using the osm2pgrouting tool on a subsequent osm file. The tool seems to have completed okay, though there were some errors on creating some of the relationships and keys, etc. (because they already existed). However, I was not sure if this approach was the right way to go. With so much data added, it would be nice to have a diagnostic to check whether the routing is correct. According to the osm2pgrouting workshop, the osm2pgrouting tool can produce certain types of errors if you are not careful.
