RS_WorldToRasterCoordY¶
Introduction: Returns the Y coordinate of the grid coordinate of the given world coordinates as an integer.
Format:
RS_WorldToRasterCoordY(raster: Raster, point: Geometry)
RS_WorldToRasterCoordY(raster: Raster, x: Double, y: Double)
Return type: Integer
Since: v1.5.0
SQL Example
SELECT RS_WorldToRasterCoordY(ST_MakeEmptyRaster(1, 5, 5, -53, 51, 1, -1, 0, 0), ST_GeomFromText('POINT (-50 50)'));
Output:
2
SQL Example
SELECT RS_WorldToRasterCoordY(ST_MakeEmptyRaster(1, 5, 5, -53, 51, 1, -1, 0, 0), -50, 49);
Output:
3
Tip
For non-skewed rasters, you can provide any value for longitude and the intended value of world latitude, to get the desired answer
