Cycle Network Intersections

Cycle network intersection numbers are added to the GPX file.

The cycle network system in Belgium and The Netherlands consists of traffic free cycle routes and quiet roads, to connect towns, villages, tourist areas and other points of interest. Sometimes a cycle path parallel to the main road has to be used, but these paths are avoided as much as possible.
Each intersection of the cycle network is marked with a two-digit number called knooppunt (node). Signs are then placed giving you directions to the next numbered node. The idea is to make your own route, just by selecting which numbered intersections to follow. At some intersections there is an information panel showing a map of that area, helping to decide which way to go.
These knooppunt numbers are only unique in a specific area and re-used in the next one, because nationwide there are many more nodes than the 99 possible using only two digits.

The system is primarily intended for local tours and day trips. Using it to navigate a long distance route like the LF1, which is signposted anyway, seems somewhat superfluous, but might be helpful in some cases.
When missing a LF1 sign, a lookup in the list of intersections can confirm you're on the right direction. Long distance signs are sometimes relative small and placed close to the ground, where knooppunt signs are always at eye-level and also found more frequent along the route.
Intersection numbers might be of great help to return after going off route for shopping, passing the night or just to visit a nearby village.

When not using a GPS device, the information boards at many intersections can give you a clue of your exact location.

To get the node numbers for the LF1 and alternative routes offered, the GPX file must be downloaded, in which they are listed as waypoints. The system works for Belgium and The Netherlands, in all regions where the route runs through, except the island of Vlieland.

On the islands to the north of Den Helder the LF1 is not signposted, for that part you have to rely on the GPX track download, or a print from the online maps, where the layers on Geocommons will show more detail than the Google maps. On the island of Texel you can now make use of the "knooppunt" system as well.
