Description
SPOT-1, launched by CNES, was the first French operational earth observing satellite. It carried two High Resolution Visible (HRV) instruments capable of simultaneous panchromatic and multispectral imaging with resolutions of 10 and 20 meters. The Earth Observing Center, NASDA, archives all data received and processes products on user demand.
Use Cases
Land-use classification based on multispectral bands (XS1, XS2, XS3)
High-resolution mapping based on panchromatic (PAN) band imagery
Oblique terrain analysis based on HRV's 27-degree off-track viewing capability
Agricultural monitoring based on spectral ranges for vegetation (0.79-0.89 micrometers)
Strengths
Two identical HRV instruments operating simultaneously
Panchromatic resolution of 10 meters
Multispectral resolution of 20 meters across three bands
Swath width of 60 kilometers for nadir viewing
