Document next steps

There are at least these paths to go down:

• Visualize Zarr using familiar javascript mapping clients, such as mapbox-gl. This could be build on or use work on xpublish (request Zarr data over HTTP RESTful API) https://github.com/xarray-contrib/xpublish/pull/88. This is appealing because a an XYZ API should work with our existing dashboard stack.
• I think most promising and straightforward: create a python script or other utility to query STAC and / or Zarr stores, generate the overviews with ndpyramid and visualize the Zarr store in a notebook or web viewer using carbonplan/maps. This will require some investigation on how to include the javascript and html in a user-friendly way in a notebook.
  • This could be used to create a Zarr-based viewer like the MS Planetary Computer data viewer for COGs.
• Iterate on the approach I have taken to visualize COGs with more examples and documentation so folks wanting to use @carbonplan/maps to visualize both COG and Zarr can do so
• incorporating a regl -based map layer into our dashboard framework, this could build off @carbonplan/maps but I'm not really sure technically how it would work

Next steps:

• Interview Jeremy and Joe at carbonplan and others using Zarr (EIS, Rich) on what my be potentially useful or interesting

Noting that during our conversation with the GIBS team they mentioned an interest in @carbonplan/maps, see https://docs.google.com/presentation/d/1OW3wZnKX6mX7IWwm_JHiXmmILAX3h_Vgl_bM0Tt-2ek/edit#slide=id.g108d6ee08a9_0_70

This seems like additional support for building tools for visualizing Zarr via xyz tiling, since I don't think that Worldview would necessarily include regl in their stack but I don't know much about the Worldview backend to say.
