Keep Right/210 loopings

From OpenStreetMap Wiki
Jump to: navigation, search

These errors contain self intersecting ways.

Author's comment:

There should be two types of ways:

  • straight ways like A,B,C,D
  • closed loop ways like A,B,C,D,A

anything else like A,B,C,D,A,B looks like an error. So any way may contain up to one node twice at most. If any node is found more than twice in the same way or if more than one node is found twice it looks like an error. Any way with only 2 different nodes in it, having one node more than once, is also an error.

Message: This way contains node #$1 $2 times. This may or may not be an error

Author's comment:

Any way that contains any single node more than twice is considered an error.

Author's comment:

Any way may contain just one node twice. If more than one node is found twice it is considered an error.
