I'm trying to fill nodata values (32767) in some SRTM elevation data using gdal_fillnodata.py. <br><br>But the output file has interpolated pixels all set to zero rather than an average of the surrounding pixels.<br>A new output file is created, (surprisingly quickly) so I assume the script is working OK.<br>
<br>Any pointers/assistance much appreciated.<br><br>Simon<br>
