geos.GEOSDistance ⇒ number ⏏
Computes the distance between the closest points of two geometries.
Kind: Exported member
Returns: number - 1 on success, 0 on exception.
| Param | Type | Description |
|---|---|---|
| g1 | number | The first geometry to measure from. |
| g2 | number | The second geometry to measure to. |
| dist | number | A pointer to a double variable where the distance will be stored. |
geos.GEOSDistanceIndexed ⇒ number ⏏
Computes the distance between two geometries using an indexed algorithm. Useful when one or both geometries is very large.
Kind: Exported member
Returns: number - 1 on success, 0 on exception.
See: geos::operation::distance::IndexedFacetDistance
Since: 3.7
| Param | Type | Description |
|---|---|---|
| g1 | number | Input geometry pointer. |
| g2 | number | Input geometry pointer. |
| dist | number | Pointer to be filled in with distance result. |
geos.GEOSDistanceIndexed_r ⇒ number ⏏
Computes the distance between two geometries using an indexed algorithm. Useful when one or both geometries is very large. This is a thread-safe version of GEOSDistanceIndexed.
Kind: Exported member
Returns: number - 1 on success, 0 on exception.

Since: 3.7
| Param | Type | Description |
|---|---|---|
| handle | number | The context handle.pointer |
| g1 | number | Input geometry pointer. |
| g2 | number | Input geometry pointer. |
| dist | number | Pointer to be filled in with distance result. |
geos.GEOSDistanceWithin ⇒ number ⏏
Tests whether two geometries are within a specified distance of each other.
Kind: Exported member
Returns: number - 1 if the geometries are within the distance of each other, 0 if not, or -1 on error.
See: GEOS C header file
| Param | Type | Description |
|---|---|---|
| g1 | number | A pointer to a GEOS geometry object. |
| g2 | number | A pointer to another GEOS geometry object. |
| distance | number | The distance threshold to test. |
geos.GEOSDistanceWithin_r ⇒ number ⏏
Checks if two geometries are within a given distance of each other.
Kind: Exported member
Returns: number - A char value that is 1 if the geometries are within distance, 0 if not, or -1 on error.
