[gdal-dev] Remapping nodata

[Brad Hards]

I'm working on the geopackage elevation extension experiment, and trying to
produce some GeoTIFF tiles that get inserted into sqlite. 

I need to remap the existing nodata (nan) to some other value that I can 
insert into a sqlite table as a number (say zero).

I had a long explanation of what I'm doing here, but it is actually explained 
in the docs: "Note that, if the input dataset has a nodata value, this does 
not cause pixel values that are equal to that nodata value to be changed to 
the value specified with this option. "

Is there an easy way to do that conversion?
