| Calculates the area of a given geometry. |
| Determines if geometry A contains geometry B. |
| Calculates the convex hull of the specified geometry. |
| Returns a corrected version of the specified geometry. |
| Determines if geometry A covers geometry B. |
| Determines if every point of geometry A lies inside or on the boundary of geometry B. |
| Compares two geometries and determines if their intersection spatially crosses. |
| Returns a geometry representing the difference between two geometries. |
| Determines whether two geometries are disjoint, i.e. whether their intersection is empty. |
| Calculates the distance between two geometries. |
| Determines whether two geometries are spatially equal, i.e. whether the first geometry is included in the second, and vice versa. |
| Checks whether two geometries have a non-empty intersection. |
| Returns a geometry representing the intersection of two geometries. |
| Checks whether the specified geometry is valid according to the OGC rules. |
| Calculates the length of a given geometry. |
| Determines whether two geometries overlap. |
| Calculates the perimeter of a given geometry (polygon or multipolygon). |
| Serializes a geometry using the specified DSV format. |
| Serializes a geometry using the Well-Known Text (WKT) format. |
| Calculates the symmetric difference between two geometries. |
| Determines whether two geometries touch. |
| Returns a geometry corresponding to the union of two geometries. |
| Determines whether geometry A is completely within geometry B (i.e., geometry B completely contains geometry A). |
| Adds a new point to a geographic linestring. |
