The SpatioTemporal Asset Catalog (STAC) is an open standard that’s reshaping how we find, share, and use geospatial and Earth observation data. This session gives new users and data providers the practical essentials for getting started with STAC and using it well.

We’ll break down the core concepts—Catalogs, Collections, Items, and Extensions—and explain how they fit together to organize spatiotemporal data in a modern, cloud-native way. For users, we’ll cover how to search, filter, and work with STAC data efficiently. For data providers, we’ll share best practices for publishing well-structured metadata, choosing extensions, and lessons learned from real-world implementations.

Attendees will leave with clear, actionable tips to avoid common pitfalls and get the most out of the growing STAC ecosystem—whether you’re building your first Collection or just trying to find and use data more effectively.
