| # ST_BuildArea |
| |
| Introduction: Returns the areal geometry formed by the constituent linework of the input geometry. |
| |
|  |
| |
| Format: `ST_BuildArea (A: Geometry)` |
| |
| Return type: `Geometry` |
| |
| Since: `v1.2.1` |
| |
| Example: |
| |
| ```sql |
| SELECT ST_BuildArea(ST_Collect(smallDf, bigDf)) AS geom |
| FROM smallDf, bigDf |
| ``` |
| |
| Input: `MULTILINESTRING((0 0, 10 0, 10 10, 0 10, 0 0),(10 10, 20 10, 20 20, 10 20, 10 10))` |
| |
| Output: `MULTIPOLYGON(((0 0,0 10,10 10,10 0,0 0)),((10 10,10 20,20 20,20 10,10 10)))` |
