#10875 new enhancement

Flag waterway/road crossing with missing tunnel/bridge attr

Reported by: jengelh@… Owned by: team
Priority: normal Milestone:
Component: Core validator Version: tested
Keywords: Cc:

Description

The validator should flag crossings of road and waterways where tunnel/bridge attribute is absent on both objects. (This in addition to the already-existing check that the layer= values are different.)

Encountering a crossing of two ways with properties

  • waterway=* layer=-1
  • highway=primary|... layer=0

should be flagged. From real-world possible construction practices, we know that one of the two has to hold true: Either the waterway is tunneled in some form under the road, or the road is built as a bridge.

[Current OSM version 1.0-7777 appears not having such a check.]

Meanwhile, I get a warning suspicious tag combination - Long waterway with layer=-1 but without a tag which defines it as tunnel or underground. Remove layer or add a tunnel tag if applicable. Also check crossing bridges and their layer tags. about the waterway but not for high- or railway.

For a general approach see #9819.
