Validator - false positives in "way end node near other way"
|Reported by:||singularita@…||Owned by:||dmuecke|
Description (last modified by mdk)
Check for "way end node near other way" is useful, however in some areas it finds many false positives.
Minimal distance to trigger this warning seems to be 10 (by default).
But what unit it is? when the preference is read, the number is divided by some arbitrary number 6378135.0
What is meaning of that number? No documentation in the source
I've collected some examples of false positives found by validator, along with some ideas how to avoid them:
validator-deadend.png - T-junction near end of way
There is branching (T-junction) close to end of way. This shows false alarm, even though the way in warning is connected to the way with the endnode.
validator-platform.png - Parallel railway tracks or platforms
Railway platforms or tracks running in parallel - these can be as close as 5 meters.
Have some smaller distance to trigger the warning, if both ways (the one with end node and the one close to the node) are parallel or very close to parallel
validator-powerline.png - highway end node close to powerline
validator-stream-road.png - highway end node close to stream
Sometimes features are running quite close to each other "by design".
Power lines often are placed with little regard of what is below them and endpoint of highway ending up near powerline is surely not connected to it.
Sometimes stream run right behind the streets (the streets are ended just before the stream) and they are also not connected
Therefore for "incompatible" features (highway vs waterway, powerline vs waterway/railway/highway) that should not be probably connected
(highway connected to the powerline does not make sense), the distance should be lower too.
I think for these cases, some lower distance threshold (one quarter by default, perhaps ....) should be used
