Compute statistics and histograms of geo-spatial data.
|SafeGetStatistics(band, approxok, force)||Retriewe statistics form a GDAL raster band in a safe way.|
|computestats(dataset[, bands, computestats, ...])|
|copy_dataset_subwin(dataset, srcwin[, ...])|
|namedtuple(typename, field_names[, verbose, ...])||Returns a new subclass of tuple with named fields.|
|HistogramRequest([hmin, hmax, nbuckets, ...])|
|Statistics||Statistics(min, max, mean, stddev)|
Enable histogram computation.
Flag for out of range values handling.
If set then values below the histogram range will be mapped into the first bucket, and values above will be mapped into last one. Otherwise out of range values are discarded.
Number of buckets for histogram comutation.
Retriewe statistics form a GDAL raster band in a safe way.
If it is not possible to get statistics (e.g. because the force flag is set to false and statistics are not available, or because the approxok is set and there are too many nodata elements in the raster band) then a tuple of four None is returned.
in order to check errors due to nodata values the GDAL internal error status is reset.
