Cloudless Sentinel-2 Docs

Who We Are​

At ClearSKY Vision, we are committed to transforming the landscape of Earth observation. Our mission is to enhance the temporal revisit capabilities of optical satellites, making Earth observation data more relevant, immediate, and actionable. By leveraging advanced AI and satellite-agnostic data fusion techniques, we aim to maximize the value of existing satellite data, enabling the seamless integration of various data sources.

Why does this matter? We want to empower decision-makers with reliable optical imagery — even in challenging cloud-prone conditions. This unlocks new possibilities in environmental monitoring, resource management, and countless other domains, ensuring accessible and consistent insights.

What Is It?​

The ClearSKY Vision service provides cloudless, multi-spectral Sentinel-2 (Level-2A) imagery. By harnessing a unique blend of data from multiple satellites (including Sentinel-1, Sentinel-2, Sentinel-3, and Landsat 8/9), and applying advanced deep learning techniques, we tackle frequent challenges like:

  • Cloud cover
  • Cloud shadows
  • Missing pixels

ClearSKY is a near real-time service that does not interpolate future data — no future data is used in creating any image. You can order both historical and live data. The standard product delivers 10 spectral bands from the Sentinel-2 MSI sensor (omitting aerosol/atmospheric bands: B01, B09, B10). It remains fully compatible with original Sentinel-2 Level-2A products, allowing you to swap your existing Sentinel-2 data pipeline in place with minimal adjustments. Our cloudless imagery is similar to original Sentinel-2 data and only deviates slightly to improve usability and accessibility.

Why Choose Us?​

We value flexibility and have built an ordering system that lets users configure image frequency, input satellites, AI models, and more. Our data is unique due to the following features:

  • Frequent, cloudless multi-spectral imagery
    Specify any frequency (daily to weekly) and gain access to consistent imagery without clouds or shadows.

  • Leverage multiple satellites
    We incorporate data from up to 11 satellites, yet the data remains easy to use as if it came from one source.

  • No need for cloud/shadow masks
    All our images are 100% cloud-free. You can focus on deriving insights instead of data cleaning and merging.

  • Wall-to-wall coverage
    Unlike standard satellite images that follow strict orbits, our data ensures continuous coverage.

  • Affordable, analysis-ready data
    Obtain up-to-date optical imagery at competitive and transparent pricing.

  • Fully compatible with Sentinel-2
    Simply swap to our data in place of your original Sentinel-2 or use both data sources without hassle.
