Analysis Ready Data Resources

CEOS ARD Webinar #2 (SAR) – February 1 & 2, 2021

This webinar was organised by CEOS to inform about the CEOS Analysis Ready Data for Land (CARD4L) specifications developed for Synthetic Aperture Radar (SAR) sensors.

CEOS ARD Webinar #1 – July 1, 2020

This is the first in a series of webinars that explore various aspects of both CEOS Analysis Ready Data and Future Data Architectures.

FORCE: Framework for Operational Radiometric Correction for Environmental monitoring

FORCE is intended to be an all-in-one solution for the mass-processing of selected medium-resolution satellite image archives to enable large area + time series applications. Currently supported are Landsat 4/5 TM, Landsat 7 ETM+, Landsat 8 OLI and Sentinel-2 A/B MSI. The software is capable of processing Level 1 products as obtained from space agencies to Level 2–4 products, including Analysis Ready Data.

A Layman’s Interpretation Guide to L-band and C-band Synthetic Aperture Radar Data

This “layman’s” guide was developed to provide users who have little or no experience of spaceborne Synthetic Aperture Radar (SAR) data with a simple reference document that outlines some basic concepts of radar remote sensing, presents some commonly used SAR datasets, and provides some examples of how a few different land cover types may appear in SAR imagery.

CEOS Analysis Ready Data for Land Information Notes

These notes have been written to summarise the benefits of CEOS Analysis Ready Data for Land for different stakeholders. There are three notes, one each for: Data Producers, Data Distributors, and Data Users.

CEOS Analysis Ready Data for Land (CARD4L) October 2018 Status Report

Steve Labahn (USGS, LSI-VC Co-Lead) presented this update on CARD4L at the 32nd CEOS Plenary in October 2018.

Analysis Ready Data Defined

Chris Holmes (Product Architect, Planet) examines the core of ARD today and presents a vision of how the Earth observation industry can advance cross-provider ARD to make data even more user-friendly.


The CEOS Land Surface Imaging Virtual Constellation (LSI-VC) served as the forum for developing the CEOS Analysis-Ready Data definition. CARD4L underpins a large amount of the future data architectures work being progressed within CEOS. The CARD4L definition was endorsed by the CEOS Plenary in 2016.
