A ford is a small part of a highway where a waterway runs over it.
How to Map
- use a single node ford where a highway crosses a waterway that is mapped as a linear stream without riverbanks
- use the way-method for larger streams with mapped riverbanks, see waterway=riverbank
The highway should share nodes with the riverbanks where it crosses them and also a node with the waterway=* where they cross. Split the highway between the riverbanks and apply ford=yes to this segment (in addition to all other information pertaining to the highway).
If the approach (up and down to the riverbank) to the ford is much different from the ford itself, it might make sense to split the way and tag them appropriately (incline=* might apply for example).
- surface=* Obvious values here would be concrete, paved, sand, gravel and mud etc.
- depth=* Normal depth you might encounter. Probably deeper during flood or when raining heavily. Perhaps even set to 0 for fords that are dry most of the year.
- layer=* This should be the same as the crossing road. This is not set in most cases. The way is both on the highway and in the waterway and not separated logically as a stream under a bridge would be.
