A small utility for generating ND array pyramids using Xarray and Zarr.
Ndpyramid can be installed in three ways:
Using the conda package manager that comes with the Anaconda/Miniconda distribution:
conda install ndpyramid --channel conda-forgeUsing the pip package manager:
python -m pip install ndpyramidTo install a development version from source:
git clone https://github.com/carbonplan/ndpyramid
cd ndpyramid
python -m pip install -e .Depending on your use case you can specify optional dependencies on install.
python -m pip install "ndpyramid[xesmf]" # Install optional dependencies for regridding with ESMF
python -m pip install "ndpyramid[dask]" # Install optional dependencies for resampling with pyresample and Dask
python -m pip install "ndpyramid[complete]" # Install all optional dependencies
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.
