Hi,
Run:
gdalinfo input.tif -stats
See among other information:
...
Band 1 Block=1905x1 Type=Float32, ColorInterp=Gray
Minimum=643.147, Maximum=927.145, Mean=735.006, StdDev=69.669
NoData Value=-3.402823e+38
Metadata:
STATISTICS_MINIMUM=643.14666748047
STATISTICS_MAXIMUM=927.14501953125
STATISTICS_MEAN=735.00611216951
STATISTICS_STDDEV=69.669350319879
STATISTICS_VALID_PERCENT=48.23
It means that 100-48.23=51.77 percent of the pixels are nodata, and nodata
pixels have a value -3.402823e+38.
You must just tell in your next processing steps that your .xyz file contain
also nodata values, just like the original data.
