| # ST_Project |
| |
| Introduction: Calculates a new point location given a starting point, distance, and azimuth. The azimuth indicates the direction, expressed in radians, and is measured in a clockwise manner starting from true north. The system can handle azimuth values that are negative or exceed 2π (360 degrees). The optional `lenient` parameter prevents an error if the input geometry is not a Point. Its default value is `false`. |
| |
|  |
| |
| Format: |
| |
| ``` |
| ST_Project(point: Geometry, distance: Double, azimuth: Double, lenient: Boolean = False) |
| ``` |
| |
| ``` |
| ST_Project(point: Geometry, distance: Double, Azimuth: Double) |
| ``` |
| |
| Return type: `Geometry` |
| |
| Since: `v1.7.0` |
| |
| SQL Example: |
| |
| ```sql |
| SELECT ST_Project(ST_GeomFromText('POINT (10 15)'), 100, radians(90)) |
| ``` |
| |
| Output: |
| |
| ``` |
| POINT (110 14.999999999999975) |
| ``` |
| |
| SQL Example: |
| |
| ```sql |
| SELECT ST_Project( |
| ST_GeomFromText('POLYGON ((1 5, 1 1, 3 3, 5 3, 1 5))'), |
| 25, radians(270), true) |
| ``` |
| |
| Output: |
| |
| ``` |
| POINT EMPTY |
| ``` |
