Hi I have seen some GeoTIFFs for DSMs (float32) with NaN as no-data value. It was not set in the metadata, but worked as that. I think I have also seen it with NaN set in the metadata. Also many other numbers as no-data value, like -10000 or -9999 or -8888 (yes, and many other posible values). Is there any reason to prefer or discourage NaN as a no-data value for a float32 GeoTIFF?
