| # ST_SimplifyPreserveTopology |
| |
| Introduction: Simplifies a geometry and ensures that the result is a valid geometry having the same dimension and number of components as the input, and with the components having the same topological relationship. |
| |
|  |
| |
| Return type: `Geometry` |
| |
| Since: `v1.0.0` |
| |
| Format: `ST_SimplifyPreserveTopology (A: Geometry, distanceTolerance: Double)` |
| |
| SQL Example |
| |
| ```sql |
| SELECT ST_SimplifyPreserveTopology(ST_GeomFromText('POLYGON((8 25, 28 22, 28 20, 15 11, 33 3, 56 30, 46 33,46 34, 47 44, 35 36, 45 33, 43 19, 29 21, 29 22,35 26, 24 39, 8 25))'), 10) |
| ``` |
| |
| Output: |
| |
| ``` |
| POLYGON ((8 25, 28 22, 15 11, 33 3, 56 30, 47 44, 35 36, 43 19, 24 39, 8 25)) |
| ``` |
