Open Data

View GB composite imagery

The data are derived from Sentinel-1 satellite data, which delivers all-weather, day and night, radar imagery of the Earth’s surface every 6-24 days at a spatial resolution of 10 m. The maps shows 'surface texture’ which enables a user to identify different surface structures, such as forests, agricultural regions, urban areas and inter-tidal extents. It can also reveal information regarding moisture in soil and vegetation. This information can be used in a variety of applications, to help detect, monitor and measure environmental activity and change over time. 

Why is the image stripy? The stripes are due to variations in soil moisture content and viewing angle, between satellite passes.

Data Services

We offer easy access to free and open data products for download straight to your desktop. The data are regularly updated, thanks to routine availability of satellite imagery which offers data in near real-time. This information is invaluable in many practical environmental and agricultural monitoring applications.



As well as free and open imagery we will be providing, in the near future, a number of ‘Premium’ service options that build on our expertise to deliver not only imagery but also change and feature analysis.

Our Data Products

The free open data option provides access to composite imagery of Great Britain. There is a rolling programme to introduce more areas of the world and we will be making announcements in due course.

The map interface enables a registered user to choose from one of four seasonal time periods, pan and zoom and then select an area of interest for download complete with relevant metadata. The data are downloaded in a format suitable for use in a geographic information system for further analysis.

A user registered to our free open data service can also view time series and feature analysis data. The free time series analysis is based upon Eurostat LUCAS point locations across Great Britain, over time. By upgrading to one of our premium service options a user can subscribe to select and access time series data for their own areas, across Great Britain.

We offer an 'Enterprise' service which includes a 'Data Services API' and bespoke image processing and analysis options.Please contact us for further information.

User Stories

We have created some typical 'user stories' to illustrate how our data services products can be used. We will add to these in due course:



Open Data

The proliferation of open data, including Earth observation imagery from new and existing satellite constellations, is opening up exciting new opportunities in environmental and agricultural applications.

The development of this data service has been made possible as a result of receiving funding from ODINE (Open Data Incubator for Europe). Commenting on our service offering ODINE said:

Environment Systems has a convincing track record and we believe that an uptake of their service would be exceptionally beneficial to society. We also believe that they understand the open data ecosystem.”
