Although I live in The Netherlands, my home is very close to the border with Belgium (<1 km) and I commute through Belgium as well. So I'll do most of my mapping in Belgium. When I started, the immediate Belgian vicinity was completely unmapped. This is why I'm also in the Users in Belgium group, so I can be found there as well. :)


Mostly using GPS in the car, and lately on the bike. I have an HTC Touch HD smartphone with WM6.1 and a Holux M-1200 51-channel GPS receiver, and am currently using OSMtracker.

I'm editing in a mix of environments. Main editing is done with JOSM, and Potlatch for touching up the odd tag here and there.

Route relation & Split routes

This section is about clarifying the forward/backward role in route relations. While this is also used in cycle node network tagging, its scope is wider, since this touches on all type=route relations.

A split route is a route where different paths are followed depending on the direction the route is followed. Examples of this would be oneway roads, or access restrictions.

The route relation for this should use proper forward/backward roles. These roles tell the direction that a way can be travelled, with respect to the direction of the way as it exists in the OSM database. This could be different than the direction you're taking that road in real life.

Some examples:


section role
B forward
C forward

In the above example, the route splits up in 2 separate ways, due to these being oneway. A more complex example, where you have to follow different routes, but which aren't necessarily all drawn in the same direction:


section role
B forward
C backward
D forward
E backward
