| # ST_MaxDistance |
| |
| Introduction: Calculates and returns the length value representing the maximum distance between any two points across the input geometries. This function is an alias for `ST_LongestDistance`. |
| |
|  |
| |
| Format: `ST_MaxDistance(geom1: Geometry, geom2: Geometry)` |
| |
| Return type: `Double` |
| |
| Since: `v1.6.1` |
| |
| SQL Example: |
| |
| ```sql |
| SELECT ST_MaxDistance( |
| ST_GeomFromText("POLYGON ((30 10, 40 40, 20 40, 10 20, 30 10))"), |
| ST_GeomFromText("POLYGON ((10 20, 30 30, 40 20, 30 10, 10 20))") |
| ) |
| ``` |
| |
| Output: |
