Atmospheric Phenomenon (cyclone, storm, hurricane)
SPOT-5 was the fifth satellite in the SPOT series of CNES, introducing the new generation HRG (High Resolution Geometric) and HRS (High Resolution Stereoscopic) sensors. Thanks to the same imaging characteristics, SPOT-5 ensured service continuity consistent with previous SPOT satellites.
The HRG instrument on board of SPOT-5 provided 2.5m spatial resolution in the panchromatic band and 10 m in the multispectral mode (3 bands). The SWIR band imagery remained at 20 m. The swath width varied from 60 km (nadir) to 80 km when angled at the maximum limit from nadir.
The HRS instrument instead provided large-area along-track stereoscopic panchromatic imagery. It featured two telescopes allowing a 20o fore view and a 20o aft view over a 120 km swath. A spatial resolution of 10 m was provided in cross-track and 5 m (parallax direction) in along-track.
- Level 1A: Radiometric correction of distortions due to differences in sensitivity of the elementary detectors of the viewing instrument. Intended for users who wish to do their own geometric image processing.
- Level 1B: Radiometric correction identical to that of level 1A. Geometric correction of systematic effects (panoramic effect, Earth curvature and rotation). Internal distortions of the image are corrected for measuring distances, angles and surface areas. Specially designed product for photo-interpreting and thematic studies.
- Level 2A: Radiometric correction identical to that of level 1A. Geometrical correction done in a standard cartographic projection (UTM WGS84 by default) not tied to ground control points. Allowing for possible differences in location, this product is used to combine the image with geographical information of various types (vectors, raster maps and other satellite images).
Resolution: 20 to 2.5 metres
