    @turf/planepoint

    planepoint

    Takes a triangular plane as a Polygon and a Point within that triangle and returns the z-value at that point. The Polygon should have properties a, b, and c that define the values at its three corners. Alternatively, the z-values of each triangle point can be provided by their respective 3rd coordinate if their values are not provided as properties.

    Parameters

    • point Coord the Point for which a z-value will be calculated
    • triangle Feature<Polygon> a Polygon feature with three vertices

    Examples

    var point = turf.point([-75.3221, 39.529]);
    // "a", "b", and "c" values represent the values of the coordinates in order.
    var triangle = turf.polygon([[
      [-75.1221, 39.57],
      [-75.58, 39.18],
      [-75.97, 39.86],
      [-75.1221, 39.57]
    ]], {
      "a": 11,
      "b": 122,
      "c": 44
    });
    
    var zValue = turf.planepoint(point, triangle);
    point.properties.zValue = zValue;
    
    //addToMap
    var addToMap = [triangle, point];

    Returns number the z-value for interpolatedPoint
