Sharing expertise to make environmental science data more widely accessible
04 Nov 2021





The Challenge:

The Joint Nature Conservation Committee (JNCC)​ working with the Department for Environment, Food and Rural Affairs’ Earth Observation Centre of Excellence identified the need for tools and services to enable rapid analysis of Earth observation data in support of decision-making across the nations of the UK.

They needed a large quantity of Sentinel-1 and 2 data to be standardised and pre-processed into data products in a common form ready for analysis, thus reducing duplicated effort and the potential for inconsistencies in data preparation.

The Solution:

CEDA are providing access to processing for Scotland and Northern Ireland and archival facilities to enable the creation of ARD from the Sentinel-1 and 2 missions for the UK.

JASMIN, the data intensive supercomputer, makes it easier to access by providing a large centralised store, the CEDA Archive, to host and disseminate standardised, pre-processed data products to the UK public sector.

The Outcome:

CEDA now holds 111.5 TB of this Sentinel ARD which is increasing by roughly 2.5 TB per month and covers England, Scotland and Northern Ireland.

ARD is already being used by the public sector for habitat mapping, monitoring forest change and crop mapping. It is estimated that access to ARD products could save up to 70% of project time.

CEDA are adding the ARD into the Satellite Data Finder so that users can search for products over areas of interest.

​Ulric Wilson, Co-Team Leader, Digital and Data Solutions, JNCC said:
“JASMIN’s huge interactive and batch computing environment has allowed us to scale up our processing workflows for Sentinel-1 and Sentinel-2 Analysis Ready Data. JNCC are helping public sector partners develop applications based on the ARD in the CEDA Archive using JASMIN’s cloud computing facilities. Direct access to the shared archive of ARD allows partners to focus resources on innovative analyses, rather than low level data preparation, including landscape monitoring and change detection, crop mapping, managed burning and wildfire extent.”
