Description (last modified by warmerdam) (diff) 

GDAL sees the datatype of GRID as Int16 even if the correct data type is 
UInt16. Tested with GDAL 1.2.5.0, released 2004/11/22.

Petteri,

I'm not sure why you say this is an unsigned 16bit dataset?  Internally 
all Arc/Info grids are 32bit integer (or 32bit float).  I just classify to 
a restricted dataset based on the min/max values to reduce disk space when
possible.  So while I *could* have easily classified this dataset as UInt16
it is equally value as Int16.  There is no values in the 32K to 64K range
for instance. 

So why do *you* feel it is UInt16?
