zarr-developers / geozarr-spec

This document aims to provides a geospatial extension to the Zarr specification. Zarr specifies a protocol and format used for storing Zarr arrays, while the present extension defines conventions and recommendations for storing multidimensional georeferenced grid of geospatial observations (including rasters).

Diagramming geozarr dependencies for different ecosystems #6

Closed briannapagan closed 1 year ago

briannapagan commented 1 year ago

Following the excercise at the February 1st, 2023 GeoZarr SWG meeting (notes here) where we spent some quiet time listing use cases with the following prompt: As a [type of User], I need to [do something] with Zarr using [tool X]

I am making an attempt of mapping these dependencies for the various use cases. This is the python dependency tree for opening a **remote zarr dataset and doing some basic plotting** i.e.:

store = 'https://ncsa.osn.xsede.org/Pangeo/pangeo-forge/pangeo-forge/CMIP6-PMIP-feedstock/CMIP6.PMIP.MIROC.MIROC-ES2L.past1000.r1i1p1f2.Amon.tas.gn.v20200318.zarr'
ds = xr.open_dataset(store, engine='zarr', chunks={}) 
ds['tas'].isel(time = 1000).plot(x='lon',y='lat',cmap='magma',vmin=0, vmax=50)
