The Flemish government offers the Wegenregister (Registry of Roads) as open data. All roads are included, also "slow roads" (paths and tracks), some private roads and even future roads. They started of with the centerlines of roads from the GRB and enriched it with National Geographic Institute (NGI) data for smaller roads.
Do not take this data as absolute truth: a lot of local governments must still validate the data, there is no automatic procedure in place to feed new GRB roads to the database. So you can expect some of the "future roads" to be quite present. The NGI data is also of varying quality: it is verry complete and has generally good geometry, but it can be quite outdated.
The aim of this task is to have a look at all the roads present in the Wegenregister but not in the OSM database. You will have to use aerial photography, GPS tracks and the occasional survey to determine reality and road classification of the missing roads.

- #osmbetask2 - mapping roads with #wegenregister When saving your work, please leave the default comment but add what you actually mapped, for example "added buildings and a residential road".
When you start editing, the background will be black with roads as they exist in the Wegenregister shown in red. This data is very complete and quite exact. But it might be outdated and sometimes wrong. Especially for paths and trails. A lot of the missing roads are just driveways. This is no priority for OSM, but you can map them as a "Driveway" (highway=service + service=driveway).
Change the background layer for verification (this is done with the "Background settings" on the right on the screen.
Switch to AGIV aerial pictures to check if roads exist. In case of doubt, don't just copy the road. Go out to survey!
If you spot unnamed roads where you can expect a name, use the GRB to verify. You can change the "Custom" background layer to "Belgium AGIV GRB Flanders", or check it out on Lara.
You can also use public GPS traces for verification. Open Background Settings and activate "OpenStreetMap GPS traces". Or use this service for aggregated biking and running GPS tracks in the Custom layer:
