LeftRightSpatialCalculator

Computes relative position of Candidate input features relative to Base input features.

The geometry of a Base feature is restricted to lines.

See the example below. The Base lines are considered to be oriented from the start point to the end point (digitization sense). A Candidate feature is:

  • located to the LEFT of a Base feature if looking down the Base line in the direction of the orientation (from start to finish);
  • located to the RIGHT if the Candidate is on the right of a Base feature;
  • UNDEFINED if the Base and Candidate features intersect, or if the Base feature has a single point.
