Processing description
Product description
Radiometry:
· Detectors normalization applied (dark current offset and sensitivity gain)
· 8 bit coded – instrument digital counts (no calibration)
Geometry:
· No geometrical correction
· Each line corresponds to a full detector array acquisition (square image)
· Pixel resolution not consistent in the field of view (specially for oblique viewing)
Radiometry:
· 8 bit coded – instrument digital counts (no calibration)
Geometry:
· Data is projected in UTM projection using a world DEM (1km GSD)
· Product orientated with respect to the geographic North
· Pixel resolution is fixed, defined by the sensor and the satellite
Satellite | Channel | Spatial resolution |
---|---|---|
SPOT 1 to 4 | PAN | 10 m |
XS | 20 m | |
SPOT 5 | PAN | 5 m |
XS | 10 m | |
THR (supermode) | 2.5 m |
· As no GCPs are used in the processing location, performance corresponds to the initial one of the products:
· About 500 m (RMS) for SPOT 1/2/3
· About 200 m (RMS) for SPOT 4
· About 50 m (RMS) for SPOT 5
