SuperView-1
50 cm multispectral, four-satellite Chinese constellation
When to use
- Sub-daily revisit at sub-meter resolution across a four-satellite constellation
- Cost-effective alternative to Vantor Legion
When it's the wrong fit
- Sub-50 cm resolution needs
- Wide-area AOIs — 12 km swath means many scenes for large captures
- Workflows requiring red-edge or SWIR bands
Processing levels
Five processing levels. Levels 1–3 are applied by default on every order; pansharpening (4) runs automatically when the sensor has a panchromatic band; mosaicking (5) runs automatically when the AOI spans multiple scenes. Specify any level explicitly if you need to override the default.
| L | Output | What's applied | Status |
|---|---|---|---|
| 0 | Raw | Digital numbers (sensor counts) with no calibration or geometric correction. Delivered as unprojected GeoTIFF with sensor metadata. | On request |
| 1 | Orthorectified | Geometric correction onto a DEM. Every pixel sits at its true ground position. Customer-supplied GCPs accepted at no extra cost. | Default |
| 2 | Surface reflectance | TOA radiometric correction plus atmospheric correction. Output is the actual fraction of light reflected by the ground, comparable across dates, sensors, and sun angles. | Default |
| 3 | Pansharpened | Gram-Schmidt fusion of panchromatic and multispectral bands. Spectral ratios preserved for downstream analytics. | Default |
| 4 | Mosaicked | Seamless multi-scene composite over the AOI with ML cloud/cirrus masking and custom seam-line path-finding. Applied automatically when the AOI spans more than one scene. | Default* |
*Mosaicking applies when the AOI spans more than one scene. Single-scene orders skip it.
Water masks, tree masks, glint handling, lidar-aligned reflectance, aquatic atmospheric correction, region-tuned models — anything your downstream pipeline requires. Quoted with the order.
DSM (digital surface model) and DTM (digital terrain model), priced per area. This sensor supports stereo capture, required for elevation products.
