Description Usage Arguments Value Examples

Takes a triangular plane as a Polygon and a Point within that
triangle and returns the z-value at that point. The Polygon needs to
have properties `a`

, `b`

, and `c`

that define the values at its
three corners.

1 | ```
geo_planepoint(point, triangle)
``` |

`point` |
Feature<Point> the Point for which a z-value will be calculated |

`triangle` |
Feature<Polygon> a Polygon feature with three vertices |

(numeric) the z-value for `interpolatedPoint`
