SPOT satellites launched in 1986, 1990, and 1994 provide high-resolution visible and near-infrared imagery. The High Resolution Visible Imaging System (HRV) captures panchromatic images at 10-meter resolution and multispectral images at 20-meter resolution, covering areas of 60 x 60 km. Data is provided by SCIOPS and processed to LEVEL 2 and S products, which include enhanced geometric accuracy and map projection alignment.
Use Cases
- Land cover classification based on multispectral bands from 500-890 nanometers
- Stereoscopic terrain modeling based on oblique viewing capability for acquiring pairs
- Change detection over time based on revisiting capability up to five times per 26 days
- High-resolution mapping based on panchromatic 10-meter resolution imagery
Strengths
- Panchromatic resolution of 10 meters and multispectral resolution of 20 meters
- Oblique viewing capability allows stereoscopic pairs and increases revisiting frequency
- LEVEL 2 processing enhances geometry and location accuracy with map projection alignment
Limitations
- Row count and total dataset size are unknown, which may limit suitability assessment
- Column-level documentation is absent; field semantics must be inferred after download
- Last update date is unknown; freshness unverified
