attrs : Dictionary¶

Attributes stored in dict related to DataArray, e.g. da.attrs Default is {} empty dictionary.

coords : Dictionary/xarray.core.coordinates.DataArrayCoordinates¶

Examples

>>> from libpysal.raster import da2W, testDataArray, w2da
>>> da = testDataArray()
>>> da.shape
(3, 4, 4)
>>> w = da2W(da, z_value=2)
>>> data = np.random.randint(0, 255, len(w.index))
>>> da1 = w2da(data, w)
