STAC Overview

Purpose

Introduce STAC as a metadata and catalog pattern for discovering, organizing, and operating geospatial asset collections.

Outline

  • STAC concepts for catalogs, collections, items, assets, and extensions
  • How STAC connects metadata to cloud-native raster and vector assets
  • Designing searchable catalogs for imagery, derived products, and ML outputs
  • Operational concerns for validation, versioning, indexing, and catalog updates
  • Role of STAC in larger architectures with object storage, APIs, and processing systems

Later Examples

  • Modeling an imagery collection with assets and common metadata
  • Adding processing outputs to a catalog without losing provenance
  • Choosing extensions for raster, projection, and ML-related metadata
