OPERA Dynamic Surface Water Extent from Sentinel-1 CalVal Database (Version 1)
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/opdsw-s1-cvv1
This dataset contains the calibration/validation (CalVal) database for the OPERA DSWx-S1 product.
Description
The CalVal database is a zip file of an Amazon Web Services S3 bucket containing classification items that enable algorithm calibration and validation of OPERA products. The CalVal database contains a Reference Document that further describes the structure and usage of the database, as well as a Validation Results document.
Example notebooks demonstrating how to read the database tables, query for specific items, and download corresponding data files are available through the CalVal GitHub repository here: github.com/OPERA-Cal-Val/calval-database
