Hello! I already use gdal_Rasterize to burn pixels that are within or outside some polygons of a vector dataset. But I would like to do the opposite, keep polygons from a vector dataset based on a the value of the pixel of a raster dataset. Per example, keep polygons where the pixel's value is greater that 205.
Is there a gdal utlity I could use to do that without programming? thanks Steve Steve Toutant, M. Sc.
