I'm using an old code written by an ex-fellow and I wonder what is GID in OSM? The gid is basically used everywhere. The project uses PostGIS and PgRouting. Any pointers to that?
I know this is a naive question but I need a start. Thanks.
As an example, this method comes from this interface.
/** * @param gid the gid of the openstreetmap entity we want to retrieve * @return the OpenstreetMap entity or null if not found */ public OpenStreetMap getByGid(final Long gid) ;
