xrspatial.classify.std_mean#

xrspatial.classify.std_mean(agg: DataArray, name: str | None = 'std_mean') → DataArray[source]#

Classify data based on standard deviations from the mean.

Creates bins at mean +/- 1 and 2 standard deviations.

Parameters:

agg (xr.DataArray or xr.Dataset) – 2D NumPy, CuPy, NumPy-backed Dask, or CuPy-backed Dask array of values to be classified.
name (str, default='std_mean') – Name of output aggregate array.

Returns:

std_mean_agg – 2D aggregate array of standard deviation classifications. All other input attributes are preserved. If agg is a Dataset, returns a Dataset with each variable classified independently.

Return type:

xr.DataArray or xr.Dataset
