[Termes IGN] incendie de forêtRésumé : (Auteur) Infrared (IR) remote sensing is increasingly used in studies of vegetation fire behavior, and high spatiotemporal resolution investigations often require data to be collected from airborne platforms, for example, standard helicopters. This paper aims to extend the range of conditions under which low-cost “handheld” thermal imaging cameras can be employed in such studies, particularly by enabling the effective and efficient geometric correction of thermal imagery collected from such devices, even when viewing far off-nadir (e.g., out of a side door or window). The approach is based on the automated detection of a set of fixed thermal “ground control points,” coupled with the use of a linear transformation matrix for warping the raw IR imagery to a fixed coordinate system. The output set of geometrically corrected brightness temperature and radiance images can be used to derive fire radiative power (FRP) and flame front rate of spread (ROS). We demonstrate and test our IR image processing methods on a series of case study fires, ranging from a small-scale laboratory to a 945-m2 outdoor experimental burn. We compare mapped information on FRP obtained from simultaneous nadir and off-nadir views, where we find differences that are in part controlled by flame structure and/or view angle. In the large open fire case, we compare the mapped fire radiative energy and ROS to simultaneously acquired aerial photography that provides the position of fuel and flames in high detail, and we demonstrate how these data sets can be used to explore various aspects of fire behavior.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) With the increased availability of user generated data, assessing the quality and credibility of such data becomes important. In this article, we propose to assess the location correctness of visually generated Volunteered Geographic Information (VGI) as a quality reference measure. The location correctness is determined by checking the visibility of the point of interest from the position of the visually generated VGI (observer point); as an example we utilize Flickr photographs. Therefore we first collect all Flickr photographs that conform to a certain point of interest through their textual labelling. Then we conduct a reverse viewshed analysis for the point of interest to determine if it lies within the area of visibility of the observer points. If the point of interest lies outside the visibility of a given observer point, the respective geotagged image is considered to be incorrectly geotagged. In this way, we analyze sample datasets of photographs and make observations regarding the dependency of certain user/photo metadata and (in)correct geotags and labels. In future, the dependency relationship between the location correctness and user/photo metadata can be used to automatically infer user credibility. In other words, attributes such as profile completeness, together with location correctness, can serve as a weighted score to assess credibility.

[Termes IGN] photogrammétrie terrestreRésumé : (Auteur) The optical efficiency of parabolic trough collectors depends on their geometric agreement with the parabolic profile design which, in turn, largely depends on the structure supporting the collector. A method for assessing the degree of agreement between the measured geometry and the theoretical design surface is described, which takes into account uncertainty in the point coordinates and is based on kernel smoothing and bootstrapping methods. The technique was applied to a 12 m long parabolic trough collector module with a newly designed supporting structure. The analysis revealed that there were significant differences between the estimated and theoretical surfaces in several parts of the collector.
