RS_WorldToRasterCoord¶
Introduction: Returns the grid coordinate of the given world coordinates as a Point.
Format:
RS_WorldToRasterCoord(raster: Raster, point: Geometry)
RS_WorldToRasterCoord(raster: Raster, x: Double, y: Point)
Since: v1.5.0
SQL Example
SELECT RS_WorldToRasterCoord(ST_MakeEmptyRaster(1, 5, 5, -53, 51, 1, -1, 0, 0, 4326), -53, 51) from rasters;
Output:
POINT (1 1)
SQL Example
SELECT RS_WorldToRasterCoord(ST_MakeEmptyRaster(1, 5, 5, -53, 51, 1, -1, 0, 0, 4326), ST_GeomFromText('POINT (-52 51)')) from rasters;
Output:
POINT (2 1)
Note
If the given geometry point is not in the same CRS as the given raster, the given geometry will be transformed to the given raster's CRS. You can use ST_Transform to transform the geometry beforehand.
