Release notes
topozarr turns an Xarray dataset into a multiscale Zarr v3 store, with each level 2x coarser than the last.
The stores follow the GeoZarr conventions and are built for zarr-layer, which renders them directly in the browser.
Installation
uv add topozarr
Or with pip: pip install topozarr.
Quick example
import xarray as xr
import xproj # for CRS assignment
from topozarr import create_pyramid
ds = xr.tutorial.open_dataset("air_temperature").drop_encoding()
ds = ds.proj.assign_crs(spatial_ref="EPSG:4326")
pyramid = create_pyramid(ds, levels=2, x_dim="lon", y_dim="lat")
pyramid.write("pyramid.zarr")
See the usage guide for cloud stores, tuning, and more.
