usage

Ndpyramid provides a set of utilities for creating pyramids with standardized metadata. The example below demonstrates the usage of the pyramid_coarsen and pyramid_reproject utilities. Check out the examples gallery for more complete demonstrations.

import xarray as xr
import rioxarray
from ndpyramid import pyramid_coarsen, pyramid_reproject

# make a reprojected (EPSG:3857) pyramid
ds = ds.rio.write_crs('EPSG:4326')
pyramid = pyramid_reproject(ds, levels=2)

# write the pyramid to zarr
pyramid.to_zarr('./path/to/write')

See the docstrings and API documentation for more details about input parameters and options.
