Predicate
Tests of where points and shapes sit against each other.
This group tests whether points fall inside a polygon with geodesic edges, including holes and points on the boundary, and reports how far each point is from the edge. Developers and GIS analysts use it for geofencing and assigning points to areas. Start with point in polygon. A pitfall is a long polygon edge drawn as a straight line on a flat map; on the Earth it bows, and points near it can change sides.
I want to check whether points are inside a polygon
- Point in polygon
Whether points are inside a polygon with geodesic edges, by the winding rule and the even-odd rule, with holes, on the boundary within 1 mm, and how far each is from the edge.
