Hi Frank,
(cc Request Tracker <grass-bugs@intevation.de>)
while importing a DTM stored in an ESRI coverage I
found a NULL problem:
gdalinfo grid25x25
Driver: AIG/Arc/Info Binary Grid
Size is 8230, 9142
Coordinate System is '
Origin = (1617349.355468,5177716.393938)
Pixel Size = (25.000000,-25.000000)
Corner Coordinates:
Upper Left ( 1617349.355, 5177716.394)
Lower Left ( 1617349.355, 4949166.394)
Upper Right ( 1823099.355, 5177716.394)
Lower Right ( 1823099.355, 4949166.394)
Center ( 1720224.355, 5063441.394)
Band 1 Block=32x32 Type=Float32, ColorInterp=Undefined
Min=-235.000/1, Max=3338.541/1
NoData Value=65536
r.in.gdal -eo grid25x25 out=dtm25.veneto
[...]
r.info dtm25.veneto
Range of data: min = -340282346638528859811704183484516925440.000000
It seems that the ESRI NULL is misinterpreted somewhere.
Min=-235.000/1, Max=3338.541/1 are correct, it's in the Alps.
Perhaps you can look into this?
Thanks in advance,
Markus
