State of STAC
06-28, 10:30–11:00 (Europe/Tirane), Lumbardhi

The SpatioTemporal Asset Catalog (STAC) specifications are a flexible language for describing geospatial information across domains and for a variety of use cases. This talk will present the current state of the specifications, which includes the core STAC specification and the API specification built on top of OGC APIs. While the core specification has been stable for roughly two years and doesn't need a lot of updates, the API specification got numerous updates and is finally close to a stable release. This presentation digs into additions to STAC extensions and the latest community developments. We survey the updates to the open-source STAC ecosystem, which includes software written in Python, Node.js, and more. Finally, let's also look into the near future.

Matthew Hanson is the Geospatial Engineering Lead at Element 84, where he works with the small-sat industry and government satellite programs to develop open standards and software to support scalable, open science. With over 25 years of experience in remote sensing, machine-learning, and imaging processing, Matthew is a contributor to multiple open-source geospatial projects.
