I'm working with London OSM data (roads) with PostGIS and pgRouting.
After download the pbf file from Geofabrik and create the topology with osm2po, I've realized that some highways in London are missing (the M25 Highway around Greater London) I've tried both pbf files: Britain Islands and Great Britain, and in both is missing, but if I search for this highway via Overpass Turbo, I can download it.
¿Has anybody any idea why is this road missing in this dataset? I thought that geofabrik datasets were daily extract from OSM Database.
As a solution, I've thought in manually create the road, and then calculate the topology. ¿Could this be a solution, or would I have to do something more in order to add it to all network?
