envelope :: Geometry a -> Some Geometry
Returns a Polygon that represents the bounding envelope of this geometry. Note that it can also return a Point if the input geometry is a point.
intersection :: Geometry a -> Geometry b -> Some Geometry
Returns a Geometry representing the points shared by both geometries.
convexHull :: Geometry a -> Some Geometry
Returns the smallest Polygon that contains all the points in the geometry.
difference :: Geometry a -> Geometry b -> Some Geometry
Returns a Geometry representing the points making up this geometry that do not make up other.
symmetricDifference :: Geometry a -> Geometry b -> Some Geometry
Returns a Geometry combining the points in this geometry not in other, and the points in other not in this geometry.
union :: Geometry a -> Geometry b -> Some Geometry
Returns a Geometry representing all the points in both geometries.
unaryUnion :: Geometry a -> Some Geometry
pointOnSurface :: Geometry a -> Geometry Point
Computes and returns a Point guaranteed to be on the interior of this geometry.
centroid :: Geometry a -> Some Geometry
Returns a Point object representing the geometric center of the geometry. The point is not guaranteed to be on the interior of the geometry.
delaunayTriangulation :: Geometry a -> Double -> Geometry MultiLineString
Return a Delaunay triangulation of the vertex of the given geometry g, where tol is the snapping tolerance to use.
