Quality assessment of data from CHRIS/PROBA
Résumé
CHRIS (Compact High Resolution Imaging Spectrometer) - new imaging spectrometer carried on board a space platform PROBA (Project for On Board Autonomy) The satellite was successfully launched in late October 2001, Shriharikota (India) Region of interest – Thorney Island (UK), Chichester harbour Chichester harbour has unique wetland environment : place for rare bird colonies. Monitoring this place - important ecological task for environmental managers. To obtain a good-quality natural-coloured image of wetlands we need: nadir-taken colour CHRIS image with bands combination of corresponding spectral channels. For the quality of CHRIS images .hdr files were examined: 1) CHRIS...47AO_41.hdr (taken at +36°) 3) CHRIS...47A2_41.hdr (taken at +55°) 2) CHRIS...47A1_41.hdr (taken at -36°) 4) CHRIS...47A3_41.hdr (taken at -55°) 5) CHRIS...479F_41.hdr (taken at nadir) Images taken at the nadir are of good quality, while those at different angles have defects. The work demonstrated CHRIS/PROBA application for Earth Observation purposes, environmental mapping and GIS.
