If you use COGs and are wondering if it's time to get on the Zarr bandwagon you might be interested in this blog that Jarrett Keifer (my coworker @element84.com) and I wrote last week: element84.com/software-eng...

Is Zarr the new COG? • Element 84

We discuss the actual differences between Zarr and COG and how each stores the data contained within its files to combat the assumption that there is a discrete choice between the two.

Totally! Maybe a rust implementation could fill this role if there were bindings to other languages. See github.com/zarrs/zarrs for instance.

Yeah that makes sense, the better approach would be to implement a different sharding codec that knows how to gather the length and offset information from the TIFF header directly. That would resolve both 1 and 3.

This one is my favorite. It really showcases the practical nature of STAC. Time and place are extra important so they are extra easy to filter by.

GitHub wrapped for 2024. This is what comes of having lots of non-computer-based hobbies :)
