RADIOMETRIC CALIBRATION OF A MULTI-SPECTRAL AERIAL CAMERA

UNDER A USGS-EROS GRANT THE UNIVERSITY OF WASHINGTON HAS ACQUIRED AN INTERNATIONAL IMAGING SYSTEM (I2S) MARK I MULTI- SPECTRAL CAMERA. A PRELIMINARY EXAMINATION OF THE PHOTOGRAPH SHOWED IMAGE QUALITY VARIATIONS OF SUCH AN EXTENT THAT THE DATA WERE OF QUESTIONABLE VALUE FOR ACCURATE TONAL ANALYSIS. AS A CONSEQUENCE IT WAS DECIDED TO RE-EXAMINE THE IMAGING SYSTEM AND THE PARAMETERS AFFECTING IMAGE QUALITY. AFTER CALIBRATION AND WITH THE AID OF AN IDEALIZED ATMOSPHERIC MODEL, THE RELIABILITY OF THE RADIOMETRIC MEASUREMENTS WAS CONSIDERABLY INCREASED. A FIRST TEST SHOWED THAT AN ACCURACY IN THE NEIGHBORHOOD OF PLUS OR MINUS 3 PERCENT ABSOLUTE GROUND REFLECTION COULD BE ACHIEVED BY THE CALIBRATED SYSTEM.
