Hi,

i work with a type of data wich can have : no data value and other information like "low and hight instrument saturation". For many algorithm this value (instrument saturation ) is like "no data value".
But in gdal doc only one data value is managed.
Have you a solution for this case ?

A practical exemple is :
data is REAL typically [-2E-5, 2E-5]
no data value is -1004
instrument saturation is -1001

thanks by advance for yours suggestions.

Ludovic
