A platform for geospatial science

The Descartes Platform is the missing link in making satellite imagery useful. We collect data daily from public and commercial imagery providers, clean it, calibrate it, and store it in an easy-to-access file system, ready for scientific analysis.

Immediate, convenient, worldwide imagery access

Using our Python APIs, access any image of the Earth within seconds.

  • Input any area of interest

    Find all matching imagery within our archive. Filter results by:
    • Start and end date
    • Satellite constellation
    • Satellite spectral band
    • Cloud cover

  • Create a composite

    Generate a single composite image from your chosen range of imagery.

  • Retrieve a time stack of imagery

    View how your area of interest changes over time. We have the full historical archive for Landsat 5/7/8, MODIS, Sentinel 1/2/3.

  • Calculate NDVI or any other custom statistic

    In addition to providing the imagery, we’ll also run your calculations over each pixel within your area of interest.

A unique, expanding data archive

The Descartes Platform provides one-stop access to an unparalleled repository of pre-processed historical and real-time public and commercial satellite imagery.

Currently, the Descartes Platform ingests 5 terabytes (TB) of near real-time data per day, roughly equivalent to 5,000 hours of standard video. Our current corpus is over 5 petabytes of data (5,000 TB) with the ability to grow much larger. With sensor data growing exponentially, the Descartes Platform is designed to respond elastically to this data explosion and harness it for real-time analysis.

A hyper-scalable supercomputer in the cloud

Putting big data to work requires a platform that can ingest and process massive datasets. To tackle this problem, we built a supercomputer in the cloud.

The Descartes Platform is built to ingest virtually any kind of data — not just satellite imagery — including weather information, commodity price histories, web crawls, and sentiment analysis from social media networks.

When conducting analysis or machine learning on these massive datasets, the platform parallelizes large calculations automatically, scaling cloud resources on demand, in response to both calculation size and desired processing time. Thus, data collected over decades can be processed in hours.

Developers BETA

As satellites keep supplying new imagery, we’re constantly updating our maps, creating a precise visual record of worldwide change, ideally suited to back-testing and machine learning on our analytics platform.

Sign up for our mailing list to keep updated on the status of our beta program – coming soon and available to developers and scientists.
