Atmospheric Phenomenon (cyclone, storm, hurricane)
(SPOT-6 and 7 NAOMI)
SPOT-6 and 7 ensure the data continuity with the no longer operational SPOT-5 satellite. SPOT-6 (launched 2012) and SPOT-7 (launched 2014) provide an archive of very high resolution optical acquisition as well as the possibility to task the satellites for new acquisitions.
The optical system is one instrument made of 3 identical Korsch telescopes, each with a 200 mm aperture delivering a 60km swath at Nadir.
The ortho-products are automatically generated by the SPOT-6 and 7 ground segment, based on SRTM database or Reference3D when available. The projection available for SPOT-6 and 7 ortho-products is UTM, datum WGS84. SPOT-6 and 7 products are available in the following modes:
- Panchromatic image at 1.5m resolution
- Pansharpened colour image at 1.5m resolution
- Multispectral image in 4 spectral bands at 6m resolution
- Bundle (1.5m panchromatic image + 6m multispectral image)
- Primary: The Primary product is the processing level closest to the natural image acquired by the sensor. This product restores perfect collection conditions: the sensor is placed in rectilinear geometry, and the image is clear of all radiometric distortion.
- Standard Ortho: The Ortho product is a georeferenced image in Earth geometry, corrected from acquisition and terrain off-nadir effects.
- Tailored ortho: Aside from the Standard Ortho product, when different specifications are needed, a custom orthorectification, with a more precise 3D model provided by the client or acquired for the purpose, can be provided on demand.
Resolution: 6 to 1.5 metres
