Also were talking spheroid surface distances aka geodesics here. So unless three places lie on a great circle their distances are not cummutative, since they form a geodesic triangle.
- numbergeek666 8y agoGoogle Earth Engine's geometry constructors build geodesic geometries by default https://developers.google.com/earth-engine/geometries_planar_geodesic https://developers.google.com/earth-engine/geometries_planar... A geodesic is a locally length-minimizing curve. Equivalently, it is a path that a particle which is not accelerating would follow. In the plane, the geodesics are straight lines. On the sphere, the geodesics are great circles (like the equator). The geodesics in a space depend on the Riemannian metric, which affects the notions of distance and acceleration
