Can Validator pick up paths connected to land use boundaries ?

[anonymous]

Several times recently I have incorrectly connected a minor path (footway, cycleway etc.) to a land use boundary rather than the intended adjacent path or road. I have only noticed either this when rendering shows the error or on later review for another reason. Is the end of a path at a land use boundary something Validator could/should detect and report on ?

Yes I think this is a common problem with roads as well as footways.

I know a lot of mappers deliberately connect footways to landuse areas as well as continuing it to the adjacent path/road. So the connection itself is not an error, but maybe a if the footpath terminates at the connection with landuse, this could count as a warning. Likewise for landuse-like tags such as leisure=park.

use noexit=yes tag to indicate a dead end and that node will be ignored with recent patches I've submitted.

Patch attached:

• adds utility functions
  • AbstractPrimitive: boolean hasTag(String key, String... values)
  • ElemStyles: AreaElemStyle getAreaElemStyle(OsmPrimitive p, boolean pretendWayIsClosed), boolean hasAreaElemStyle(OsmPrimitive p, boolean pretendWayIsClosed)
  • Way: Node getFirstNode(), Node getLastNode()
• adds validation test WayConnectedToArea

Please take a look at the provided patch!

Way has already functions firstNode() and lastNode(). No need to reimplement them.

Replying to stoecker:

Way has already functions firstNode() and lastNode(). No need to reimplement them.

Right… Changed and committed.

There are plenty of false positives with this new warning, like a highway ending on a roundabout, a footway ending on a building entrance... This check should be be only restricted to landuse boundaries right now, and extended to other specific cases if needed.

Sorry to reopen again this ticket :) I have another case where this warning should not happen: when a landuse share a way segment with a highway A, and another highway B connects to A:

            _____ highway A
           /
           |
-----------|
|          |
| landuse  |-------- highway B
|          |
-----------|
           |

This is perfectly valid :)
