Exploring Cloud Native Geospatial Data Formats: Hands-on with Raster Data

Sun, 30 Aug 2026 00:00:00 +0000

Ever wonder what GDAL is doing under the hood when you read a GeoTIFF file? Doubly so when the file is a Cloud-optimized GeoTIFF (COG) on a remote server somewhere? Have you been wondering what this Zarr thing is all about and how it works? Then there’s the whole Kerchunk/VirtualiZarr indexing to get cloud-native access for non-cloud-native data formats, what’s that about?

Cloud-native geospatial is all the rage these days, and for good reason. As data sizes grow, layer counts increase, and analytical methods become more complex, the traditional download-to-the-desktop approach is quickly becoming untenable for many applications. It’s no surprise then that users are turning to cloud-based tools to scale out their analyses, or that traditional tooling is adopting new ways of finding and accessing data from cloud-based sources. But as we transition away from opening whole files to now grabbing ranges of bytes off remote servers it seems all the more important to understand exactly how cloud native data formats actually store data and what tools are doing to access it.

A virtual delivery of the cloud-native raster formats workshop for an Oceania geospatial user group: a survey of the cloud-native geospatial landscape followed by hands-on exploration of how COG and Zarr store data, reading both by hand from cloud sources using just Python.

As file sizes grow, layer counts increase, and analytical methods become more complex, the traditional download-to-the-desktop approach is quickly becoming untenable for many applications. It’s no surprise then that users are turning to cloud-based tools such as Dask to scale out their analyses, or that traditional tooling is adopting new ways of finding and accessing data from cloud-based sources. But as we transition away from opening whole files to now grabbing ranges of bytes off remote servers it seems all the more important to understand exactly how cloud native data formats actually store data and what tools are doing to access it.
