Synthetic Aperture Radar ESA Sentinel-1

Sentinel-1 (SAR)

This service provides radiometrically and spatially corrected Sentinel-1 imagery for a specified region of interest.

Sentinel-1 data products provide global synthetic aperture radar images. You must provide a region of interest and then a start date and optional end date. Note that Sentinel-1 data is available from 2017-01-01 onwards. For every day from the start to the end (inclusive), radiometrically and spatially corrected radar responses are then output as separate images representing VH and VV polarisations. The imagery is output as a series of GeoTIFF files, each with a single band representing the polarisations. Preview images are also provided. All GeoTIFF files will have the same geographic projection and resolution. Additional options allow specification of which Sentinel-1 platform, as well as options which control the aggregation of images over a number of days.

Detecting and Monitoring Solar Farms

Large scale detection and monitoring of renewable energy sources

In order to mitigate the impacts of climate change and reduce the use of fossil fuels, the implementation and use of renewable energy sources is key. Remote sensing provides valuable monitoring of solar farms that enables their efficiency, and hence output, to be tracked over time at scale, efficiently from a distance. In this case study we demonstrate the automatic detection of some solar farms in the south of England and how regular monitoring using satellite thermal imaging reports on their efficiency.

Cloud and Shadow Detection in Satellite Images

Removing uncertainty in Sentinel-2 images

There is a rapidly increasing demand for remote sensing capabilities, which calls for quick and efficient ways to transform raw data into useable insights. However, clouds and shadows in optical satellite images block the potential for creating usable insights. D-CAT offers a reliable cloud and shadow detection service which allows clients and users of Sentinel-2 imagery to identify them with ease and trust the processed results.

Platforms & APIs

Robust cloud platforms and API solutions

Being able to extract insight from data is not enough to be useable by customers to solve their problems. Needed alongside clever algorithms is the ability to develop robust, secure and useable solutions which, for example, integrate with customer systems, or provide stand-alone systems which can be used by end users.
