+## planepoint
+
+Takes a triangular plane as a [Polygon][1]
+and a [Point][2] 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][3]** the Point for which a z-value will be calculated
+-   `triangle` **[Feature][4]&lt;[Polygon][5]>** a Polygon feature with three vertices
+
+**Examples**
+
+```javascript
+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][6]** the z-value for `interpolatedPoint`
