Cloud-Removal Models

Available Models​

The following models are available for ordering, each with their strengths, limitations, and base prices:

Stratus-2​

Stratus-2 is the original ClearSKY Vision cloud-removal model and the ‘Product’ winner of the CASSINI Challenges. It leverages data from Sentinel-1 (ascending and descending), Sentinel-2, and Landsat 8/9 to produce cloudless, multi-spectral Sentinel-2 imagery. Thanks to its advanced data cleaning capabilities, Stratus-2 excels during periods with haze, thin cirrus clouds, and cloud shadows, delivering clear and accurate images. Its SAR capabilities make it particularly powerful in northern countries, where high SAR revisit frequencies significantly enhance image quality and provide more up-to-date imagery.

  • Base Price: 0.2 EUR / km²
  • Usage Units:
    • Composite: 1 UU / km²
    • Minitiles: 0.5 UU / km²
    • Tile: 0.1 UU / km²
  • Resolution: 10m / pixel
  • Required Input Satellites: Sentinel-1, Sentinel-2, Landsat 8/9
  • Optional Input Satellites: None
  • Available Data Products: B2, B3, B4, B5, B6, B7, B8, B8a, B11, B12

Stratus-2 (No Snow)​

Stratus-2 (No Snow) is a streamlined version of the award-winning Stratus-2 cloud-removal model, tailored for users who do not require snow-prediction capabilities. By excluding snow prediction, this variant offers enhanced stability and efficiency, making it an ideal choice for regions or applications where snowy imagery is irrelevant. It leverages the same advanced data sources — Sentinel-1 (ascending and descending), Sentinel-2, and Landsat 8/9 — to produce cloudless, multi-spectral Sentinel-2 imagery.

  • Base Price: 0.2 EUR / km²
  • Usage Units:
    • Composite: 1 UU / km²
    • Minitiles: 0.5 UU / km²
    • Tile: 0.1 UU / km²
  • Resolution: 10m / pixel
  • Required Input Satellites: Sentinel-1, Sentinel-2, Landsat 8/9
  • Optional Input Satellites: None
  • Available Data Products: B2, B3, B4, B5, B6, B7, B8, B8a, B11, B12

Ask API for Available Models​

You can query our API to retrieve a list of available processing models, along with their supported SatelliteConstellations. Each model lists satellite constellations that it supports and indicates whether they're optional or required.

Endpoint: GET /api/tasking/models

{
  "Data": {
    "TaskingModels": [
      {
        "Model": "Stratus2",
        "SupportedSatelliteConstellations": [
          {
            "SatelliteConstellation": "Sentinel1",
            "Optional": false
          },
          {
            "SatelliteConstellation": "Sentinel2",
            "Optional": false
          },
          {
            "SatelliteConstellation": "Landsat89",
            "Optional": false
          }
        ]
      },
      {
        "Model": "Stratus2NoSnow",
        "SupportedSatelliteConstellations": [
          // Additional satellite constellations here
        ]
      }
    ]
  },
  "Succeeded": true,
  "Error": null
}

In this example:

  • "Model" refers to the name of the available processing model.

  • "SupportedSatelliteConstellations" lists satellite constellations compatible with the model.

  • "Optional" false means that this satellite constellation is required by the model. An optional constellation would have "Optional" true.

You can use this information to determine which processing models and satellite constellations best suit your use case.
