i want to off set a raster by half cell size in XY so points created from it will be at the pixel center rather than the lower left hand corner. How can i expose these values so they don't have to be manually typed in?
the import format is ASCII grid so the information is right there in the header
ncols 200
nrows 200
xllcorner 220000
yllcorner 70000
cellsize 50
