| # ST_BoundingDiagonal |
| |
| Introduction: Returns a linestring spanning minimum and maximum values of each dimension of the given geometry's coordinates as its start and end point respectively. |
| If an empty geometry is provided, the returned LineString is also empty. |
| If a single vertex (POINT) is provided, the returned LineString has both the start and end points same as the points coordinates |
| |
| Format: `ST_BoundingDiagonal(geom: Geometry)` |
| |
| Return type: `Geometry` |
| |
| Since: `v1.5.0` |
| |
| SQL Example |
| |
| ```sql |
| SELECT ST_BoundingDiagonal(ST_GeomFromWKT(geom)) |
| ``` |
| |
| Input: `POLYGON ((1 1 1, 3 3 3, 0 1 4, 4 4 0, 1 1 1))` |
| |
| Output: `LINESTRING Z(0 1 1, 4 4 4)` |
| |
| Input: `POINT (10 10)` |
| |
| Output: `LINESTRING (10 10, 10 10)` |
| |
| Input: `GEOMETRYCOLLECTION(POLYGON ((5 5 5, -1 2 3, -1 -1 0, 5 5 5)), POINT (10 3 3))` |
| |
| Output: `LINESTRING Z(-1 -1 0, 10 5 5)` |
