containsLocation() Polyline in Polygon

Is there a possibilty to check that Polyline is in Polygon? Or I must check each points in Polyline containsLocation in Polygon? I think about importing gpx files (my Polyline) and check what administrative area (my Polygons) contains this Polyline. I was thinking about reverse geocoding for each points in Polyline, but its impossible due to geocoding limitations. Any ideas?

You have to check every point of the Polyline against your Polygon. Take into account that a Polyline can be (according to DE-9IM):

  • Within your polygon (contained) = completely contained
  • Intersect your polygon = partially contained
  • Disjoint = not contained

So, a polyline can intersect two different Polygons (your Polyline can intersect two different administrative areas)
