Hy folks,
When a raster map is created, the range is written to file in cell_misc.
Since that is given from the start, why using the second map defining the
null-values instead of simply defining a null-value outside of that range for
every map?
With the growing size of files nowadays I think reading the file twice (normal
+ nullplaceholder) and then compare them could get a long job.
Let's not argue about who should implement this 
For now it's just a easy
question and couriosity.
Cheers
Andrea
