 ## Summary
 
- OGC API - Environmental Data Retrieval provides a family of lightweight interfaces to access Environmental Data resources. Each resource addressed by an EDR API maps to a defined query pattern. In this deep dive, we provided an overview of the standard and described each of these query patterns in detail.
