I am compiling a map using the OSM data downloaded from geofabrik And when I finally get to Mkgmap it is complaining about Drive on Right roads being in the file. I believe if I put --drive-on=left option into Mkgmap that should force a drive on the left and I won't get the warning messages. I hope this is the case. But, is there any way to search the OSM database to find where these roads are ? |

If the exceptions are those ways tagged with Hi Ed. Thanks for the prompt response. These are the messages I get, it still produces a map. SEVERE (StyledConverter): 12341003.osm.pbf: Attention: Tile contains both drive-on-left (18429) and drive-on-right roads (1) SEVERE (StyledConverter): 12341010.osm.pbf: Attention: Tile contains both drive-on-left (74845) and drive-on-right roads (1) SEVERE (StyledConverter): 12341015.osm.pbf: Attention: Tile contains both drive-on-left (63268) and drive-on-right roads (4) SEVERE (StyledConverter): 12341029.osm.pbf: Attention: Tile contains both drive-on-left (97709) and drive-on-right roads (3) SEVERE (StyledConverter): 12341033.osm.pbf: Attention: Tile contains both drive-on-left (61515) and drive-on-right roads (2) SEVERE (StyledConverter): 12341034.osm.pbf: Attention: Tile contains both drive-on-left (109296) and drive-on-right roads (2) SEVERE (StyledConverter): 12341003.osm.pbf: Attention: Tile contains both drive-on-left (18429) and drive-on-right roads (1) I have no idea where the roads tagged "drive_side=right" are. As the UK drives on the left, I am guessing some roads have been missed tagged. How does the overpass link help ?

Hi Ed. Okay I am impressed with the search, it appears there are two roads with drive on the right in London, nice search,m how did you set that up ? so I am a bit more proficient next time

I didn't set it up. I found the driving_side page on the wiki http://wiki.openstreetmap.org/wiki/Key:driving_side then clicked the "uk" link under "more tools for this tag" in the box on the right and noticed there was an overpass turbo link. I suspect the tag has been added deliberately and in those instances you end up driving on the right because of circumstances linked to one way systems.

I am surprised Mkgmap throws out a dozen or so errors based on 2 roads in London, but hey ho, I now understand how to search and as I don't drive in London all is well with the world. Thanks Ed, much appreciated

I presume one of these is the famous service road for the Savoy Hotel (an example of the rule that there is always at least one exception in any large enough data set). See http://en.wikipedia.org/wiki/Right-_and_left-hand_traffic#Exceptions_to_the_rule
