Hello, guys,<div> </div><div>I have several DEMs from USGS GTOPO30, and by merging them with gdal_merge.py, it seems the no data value can not be assigned?</div><div> </div><div>the command is like:</div><div>gdal_merge.py -of GTiff -o Europe.tiff -n -9999 -co "PROFILE=GeoTIFF" -co "INTERLEAVE=PIXEL" -co "COMPRESS=NONE" -co "TILED=YES" *.DEM</div>
<div> </div><div>and to check it with "gdalinfo -stats Europe.tiff ", i got:</div><div><div> </div><div>Band 1 Block=256x256 Type=UInt16, ColorInterp=Gray</div><div> Minimum=1.000, Maximum=65535.000, Mean=30979.953, StdDev=27318.154</div>
<div> Metadata:</div><div> STATISTICS_MINIMUM=1</div><div> STATISTICS_MAXIMUM=65535</div><div> STATISTICS_MEAN=30979.952856589</div><div> STATISTICS_STDDEV=27318.154016739</div><div> </div><div>seems the no data value is now 65535 ? how to assign it correctly?</div>
