Ground Spectroradiometric Measurements in Support of the Validation of the Calibration of Digital Airborne Imaging Spectrometer (dais 7915) Data*

چکیده
A standard reference test site is flown using the DAIS 7915 imaging spectrometer over Central Switzerland. Simultaneous to this overflight extensive ground measurements are carried out. A sun photometer, a radiosonde, and two spectroradiometers are used simultaneously during the overflight to support the in– flight calibration and validation of the DAIS 7915. The calibration of all instruments is discussed and the modelling process of the at–sensor radiances of the DAIS 7915 is described.

Dais System Performance , First Results from the 1995 Evaluation Campaigns
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...
متن کاملUnmixing of Dais 7915 Imaging Spectrometer Data in Highly Vegetated Areas
An intensively used agricultural test site in Switzerland is covered by the DAIS 7915 imaging spectrometer in summer 1997. Three different methods of collecting endmembers for spectral unmixing are selected and compared against each other. The methods include a soil-vegetation-atmosphere-transfer approach (SVAT) based on a leaf optical properties model (PROSPECT) and a canopy model (SAIL), imag...

In July of 1997, various experimental flights were carried out with the Digital Airborne Imaging Spectrometer (DAIS7915). DAIS7915, or DAIS for short, is a European airborne imaging spectrometer and is maintained and operated by the German Aerospace Centre (DLR) at Oberpfaffenhofen. One of the 1997 experimental sites was the Peyne catchment in southern France. The objectives of the experimental...
متن کاملMulti-Channel Morphological Profiles for Classification of Hyperspectral Images Using Support Vector Machines
Hyperspectral imaging is a new remote sensing technique that generates hundreds of images, corresponding to different wavelength channels, for the same area on the surface of the Earth. Supervised classification of hyperspectral image data sets is a challenging problem due to the limited availability of training samples (which are very difficult and costly to obtain in practice) and the extreme...

Space Imaging’s Digital Airborne Imaging System (DAIS-1TM) is a 12-bit multispectral imaging platform for the generation of orthomosaics at ground sample distances ranging from 0.3 to 2 meters. At the core of the system is a custom-built four-camera assembly utilizing narrow field-of-view sensors, with exterior orientation parameters provided by an onboard GPS/IMU navigation platform. Because a...
