DAIS system performance, first results from the 1995 evaluation campaigns

Abstract

Since early 1995 DLR's Institute for Optoelectronics is operating the DAIS-7915. This new imaging spectrometer covers the electromagnetic spectrum from the visible to the thermal infrared wavelength region. The sensor has been calibrated in the laboratory and was flown on board DLR's Do-228 aircraft. Between May 1995 and November 1995 almost 100 airborne scenes were acquired. The data collected during these campaigns were intended to prove the validity of laboratory calibration, to support the improvement of the instrument and of the data processing and evaluation facility and to show the application potential of imaging spectroscopy with the DAIS. This paper will present first results describing the laboratory calibration and inflight validation in the 0.4-2.5 µm wavelength region as well as some data quality aspects. 1. INTRODUCTION The 79-channel Digital Airborne Imaging Spectrometer (DAIS-7915or DAIS), was built by GER Corp. (Chang et al., 1993) and funded by the European Union and...
