“…Absolute calibration parameters can be determined by solving, e.g., the linear parameters between DNs and radiances. This calibration procedure is similar to the methods used to calibrate satellite and video sensors (Dianguirard and Slater, 1999;Biggar et al, 2003;Pagnutti et al, 2003;Edirisinghe et al, 2004) and to method used by USGS (2004) to characterize airborne sensors. Preliminary results from use of the FGI reflectance targets for the testing and calibration of an UltraCamD photogrammetric camera were reported by Markelin et al (2005).…”

Comprehensive field-testing and calibration of digital photogrammetric systems are essential to characterize their performance, to improve them, and to be able to use them for optimal results. The radiometric, spectral, spatial, and geometric properties of digital systems require calibration and testing. The Finnish Geodetic Institute has maintained a permanent test field for geometric, radiometric, and spatial resolution calibration and testing of high-resolution airborne and satellite imaging systems in Sjökulla since 1994. The special features of this test field are permanent resolution and reflectance targets made of gravel. The Sjökulla test field with some supplementary targets is a prototype for a future photogrammetric field calibration site. This article describes the Sjökulla test field and its construction and spectral properties. It goes on to discuss targets and methods for system testing and calibration, and highlights the calibration and testing of digital photogrammetric systems.

“…For airborne sensors, a feasible vicarious calibration approach is reflectance-based test field calibration. In this method, the at-sensor radiance is predicted by measuring the reflectance of a ground target, modeling the atmosphere using a radiative transfer code and measured atmospheric properties, and then propagating the ground-target radiance through the modeled atmosphere (Dianguirard and Slater, 1999;Pagnutti et al, 2002;Pagnutti et al, 2003;Biggar et al 2003;Edirisinghe et al, 2004;USGS, 2004). A procedure for the photogrammetric sensor test field calibration is shown in Figure 3; details of this process are discussed below.…”

“…The calibration of airborne instruments is simpler than that of spaceborne instruments, because the laboratory calibration can be repeated if necessary. With airborne video systems and spectrometers, laboratory and vicarious calibration methods are used (Vane et al, 1993;Pellikka, 1998;Moran et al, 2001;Pagnutti et al, 2002;Edirisinghe et al, 2004).…”

Test field calibration is an attractive approach to calibrating and characterizing the radiometry of airborne imaging instruments. In this study, a method for radiometric test field calibration for digital photogrammetric instruments is developed, and it is used to evaluate the radiometric performance of large-format photogrammetric sensors the ADS40, the DMC, and the UltraCam D. In the study, linearity, dynamic range, sensitivity, and absOlute calibration were evaluated. The results demonstrated the high radiometric quality of the sensors tested. All the sensors were linear in response. The DMC used the 12-bit dynamic range entirely, while the ADS40 and the UltraCam D indicated close to the 13-bit dynamic range. The sensors performed quite differently with respect to sensitivity. With the DMC and the UltraCam D a risk of overexposure appeared, while the color channels of the ADS40 showed low sensitivity. Because the sensors were linear in response, they could be absolutely calibrated using linear models.
