Some operation may have different semantic depending on which boundary node rule is applied.

See for background information.

GEOS C-API only expose boundary-node-rule in the GEOSRelateBoundaryNodeRule, introduced in 3.3.0. But more functions would be affected by such rule these are:

  • Relate (we have GEOSRelateBoundaryNodeRule since 3.3.0)
  • Boundary
  • isSimple
  • Touches
  • Within
  • Contains

It would be useful to expose a way to specify the boundary node rule for each of the above operations
