“…The M ini-M CA6 was radiometrically calibrated on board an unmanned aerial system (at 30 m high) through a vicarious radiometric calibration (Slater et al, 1987) by using a selfdeveloped software, M ULRACS. Figure 2 outlines the field campaign performed which required: (i) a test area with Lambertian surfaces, (ii) a spectroradiometer for ground truth measurements and (iii) a simultaneous data acquisition between the sensor and the ground-based spectroradiometer.…”

ABS TRACT:This paper sums up the main contribution derived from the thesis entitled "Multispectral imaging for the analysis of materials and pathologies in civil engineering, constructions and natural spaces" awarded by CIPA-ICOM OS for its connection with the preservation of Cultural Heritage. This thesis is framed within close-range remote sensing approaches by the fusion of sensors operating in the optical domain (visible to shortwave infrared spectrum). In the field of heritage preservation, multispectral imaging is a suitable technique due to its non-destructive nature and its versatility. It combines imaging and spectroscopy to analyse materials and land covers and enables the use of a variety of different geomatic sensors for this purpose. These sensors collect both spatial and spectral information for a given scenario and a specific spectral range, so that, their smaller storage units save the spectral properties of the radiation reflected by the surface of interest. The main goal of this research work is to characterise different const ruction materials as well as the main pathologies of Cultural Heritage elements by combining active and passive sensors recording data in different ranges. Conclusions about the suitability of each type of sensor and spectral range are drawn in relation to each particular case study and damage. It should be emphasised that results are not limited to images, since 3D intensity data from laser scanners can be integrated with 2D data from passive sensors obtaining high quality products due to the added value that metric brings to multispectral images.

-The measurement of spectral data in the field has an important role in remote sensing, and a long history, but instruments and methods to achieve this have serious limitations under all but the most ideal conditions. Problems arise from the instruments themselves, from the environment in which they are used, and from the methodologies that are commonly adopted.The variable most commonly sought from field measurements is spectral reflectance, or more strictly the bidirectional reflectance factor (BRF), but this is dependent to some extent on the instrument used to make the measurement, and the conditions of measurement, notably the sky irradiance distribution. In this paper we argue that field spectral measurements should be recorded in the appropriate SI units, which will normally be the derived units of radiance for the flux reflected from the target and irradiance for the incident energy. Reflectance data remain a convenient way to represent the energy interactions occurring at the surface, and they have value in generic spectral libraries, but ultimately they lack reproducibility unless accompanied by much more detailed metadata than is the norm in most spectral libraries.

“…The radiance-validation work at Ivanpah Playa relies on the reflectance-based method, which has a proven history of use through the radiometric calibrations of Landsat-4 and -5 Thematic Mapper and SPOT-1, -2, and -3, the AVIRIS, and a Daedalus scanner (Balick, Golanics, Shines, Biggar, & Slater, 1991;Gellman et al, 1993;Slater et al, 1987;Thome, Gustafson-Bold, Slater, & Farrand, 1996;Vane et al, 1993). This approach uses ground-based measurements Fig.…”
