EDA STAC Extension🔗

This document explains the EDA Extension to the SpatioTemporal Asset Catalog (STAC) specification.

EDA Extension adds metadata related to EDA specific details like ImagerMode, Sensor Type, Water Cover, Radiometric Scaling, Geometric Accuracy RMSE etc that affect the view of resulting data. It will often be combined with other extensions that describe the actual data, such as the eo, proj or sat extensions.
