Discovery
The Discovery API enables searching, filtering, and sorting through a unified catalog of available content. The Discovery API also returns metadata information with the selectable options about the available content as SpatioTemporal Asset Catalog (STAC) and GeoJSON. Some results sets return links to order or stream the selected content.
The Discovery Guide includes the following:
Introduction to Discovery
This document explains the search and filter capabilities supported by the Discovery API endpoints.
STAC Item details
Understanding STAC items is central to using the Discovery API to access the Catalog. The STAC Item documentation provides an example of a STAC item for a satellite image.
Search Tutorial
The Discovery API provides methods for requesting collections or items and performing searches. For most users the search method will be the one most often used.
Gridded Search Tutorial
The Discovery API provides an imagegrid service that searches the catalog in much the same way as the standard STAC service, but returns images gridded into tiles. Tiles are 5 km by 5 km in size in UTM coordinates.
