      <p>Hi,</p>
      <p>This is a "well known" behaviour of gdal_grid in which it
        writes raster with a bottom-left corner origin, whereas most
        other GDAL utilities use a top-left corner origin. The ERS
        driver doesn't support such convention. The workaround you can
        use is to output gdal_grid as a TIFF (tmp.tif), then use
        "gdalwarp tmp.tif out.ers" to flip the origin to a top-left one.<br>

        <p>Looks to me like the ERMapper ERS driver has a bug, using the
          bottom left corner to georef the raster, instead of top left.
          I can only use it if I use local coordinates, any negative
          northings are plotted towards the north. ERS is the main
          raster format I use.</p>
        <p>I am happy to assist in sorting out the ERS format if the
          person behind it is willing to have a look at it.<br>

          <p>I am having issues with outputting ers raster file from
            gdal_grid. I import a csv as shape, then grid it and output
            as ers. The Y coords are all negative as it is in fact a
            section I simply grid as a 2D raster. Although the shape
            file plots as I expect it, the ers is flipped upside-down,
            and hung at the lowest Y value. Please note, if I use GS7BG
            it works fine.<br>
