RS_RasterToWorldCoordY

Converts raster pixel coordinates to world Y coordinate.

Usage

double RS_RasterToWorldCoordY(rast: raster, x: integer, y: integer)

Arguments

  • rast (raster): Input raster
  • x (integer)
  • y (integer)

Description

Pixel coordinates are 1-based, as in PostGIS ST_RasterToWorldCoord: (1, 1) is the upper-left pixel, and the result is the world coordinate of that pixel’s upper-left corner. Coordinates outside the grid, including 0, extrapolate along the geotransform.

Examples

SELECT RS_RasterToWorldCoordY(RS_Example(), 10, 20);
