“…Jones and Casa (2000) explain how information on plant canopies can be retrieved from their Variable Interference Filter Imaging Spectrometer, while Debryun and Veroustraete (2000) use BRDF models in the exploitation of spectroscopy data generated with the DAIS instrument. For its part, Wang (2000) outlines work in preparation in China to develop relevant airborne sensor technology. Two papers then deal with future space missions: Barnsley et al (2000) outline an instrument under construction, slated for launch on an experimental platform around 2002, while Vogt et al (2000) reflect on the advantages and implications of acquiring multidirectional and multispectral data with the proposed PRISM sensor on the LSPIM mission, a candidate Earth Explorer core mission of the European Space Agency.…”

Japan. These participants, listed in Annex 1, were involved or interested in modeling the anisotropy of the radiation field, in multiangular measurements, or in the exploitation of these tools and data in their own applications.This 3-day meeting addressed three main objectives: (1) to establish the state of the art in direct and inverse modeling techniques, including those proposed for the operational exploitation of earlier instruments * Corresponding author. 1 Downloaded by [University of Tennessee, Knoxville] at 03:21 07 June 2016 2 M. M. VERSTRAETE AND B. PINTY(e.g., geostationary satellites and the POLDER) and recently launched platforms (e.g., EOS Terra), (2) to review current and near-future multiangular air-and space-borne missions, as well as the latest developments in field and laboratory instruments, and (3) to demonstrate the usefulness of quasi-simultaneous multiangular and multispectral measurements, when exploited with appropriate models, through either an improved accuracy and reliability of the results or the generation of new geophysical products. The agenda of the conference is provided in Annex 2, and additional information on the activities of the ENAMORS project are available on the Internet at http://www.enamors.org/. CONFERENCE PROCEEDINGSThe number and diversity of contributions to this international conference called for a concomitant flexibility in publishing the proceedings. As a result, arrangements were taken to publish two special issues of well-known journals interested in remote sensing and its applications. These are Remote Sensing Reviews and the Journal of Geophysical Research-Atmospheres. The present RSR special issue contains a selection of papers derived from the posters presented at the conference, as well as a couple of papers commissioned for this particular special issue.The following contributions are logically organized around the main themes of the IWMMM-2 conference, namely the acquisition of bidirectional measurements from laboratory, field, airborne and spaceborne instruments, the mathematical representation of the anisotropy of the reflectance field as well as the development of efficient inversion procedures, and the exploitation of these tools and data in practical applications. Specifically, the first paper by Martonchik et al. (2000) reviews the definition and nomenclature of reflectance concepts. This provides a useful background to read and understand the subsequent contributions. It is followed by a couple of papers, by Rothkirch et al. (2000) and Meister et al. (2000a) describing recent results obtained with the European Goniometer (EGO) of the Space Applications Institute in Ispra, Italy. This is an indoor laboratory set up to provide accurate measurements of directional and spectral properties of small targets (scale length between about 10 and 100 cm). Another laboratory system, developed in Grenoble, France, is described by Bonnefoy et al. (2000): this installation is designed to support the interpretation of reflectance data from planetary surfaces. ...

“…Compared with satellite data, airborne images are closer to the ground measurement scale and could have more view angles. Airborne multiangular TIR data can be acquired either with a wideangle thermal camera or a thermal sensor with a rotation device (Liu et al, 2000;Wang, 2000). Because of the complexity in airborne data processing as well as component temperature retrieval itself, reports about validated results of component temperatures from airborne images are scarcely found in literatures.…”

In the process of applying the theoretic results of BRDF model study to remote sensing image data, an important step is to extract BRDF features from multi-angular images. Because of the limitations of registration, pixel alignment and the intrinsic scale of scene, it is necessary to perform spatial average to the georeferenced multi-angular images before extracting BRDF feature. Otherwise the feature will not be representative to the surface property. Based on analysis of geometrical limitations, this paper discussed how the apparent BRDF feature changes from random to order after the spatial average.
