[Termes IGN] villeRésumé : (Auteur) La thermologie infrarouge par voie aérienne pour l'évaluation des pertes thermiques des parcs immobiliers connaît un essor important depuis quelques années, sous l'impulsion des incitations aux réductions de consommation d'énergie issues d'initiatives comme les Agenda 21 ou les résolutions du Grenelle de l'Environnement. La forte médiatisation de ce type d'opération a conduit parfois à survendre les capacités de la technique à une société civile soucieuse de réduire son impact sur l'environnement. L'objectif de cet article est de replacer la thermographie aérienne dans son contexte scientifique et technique pour mieux préciser ce qu'il est possible d'en attendre et comment en exploiter au mieux les résultats.

[Termes IGN] trajectographie (positionnement)Résumé : (Auteur) Three multi-spectral bands of the Liss-4 camera of IRS-P6 satellite are physically separated in the focal plane in the along-track direction. The time separation of 2.1 s between the acquisition of first and last bands causes scan lines acquired by different bands to lie along different lines on the ground which are not parallel. Therefore, the raw images of multi-spectral bands need to be registered prior to any simple application like data visualization. This paper describes a method for co-registration of multiple bands of Liss-4 camera through photogrammetric means using the collinearity equations. A trajectory fit using the given ephemeris and attitude data, followed by direct georeferencing is being employed in this model. It is also augmented with a public domain DEM for the terrain dependent input to the model. Finer offsets after the application of this parametric technique are addressed by matching a small subsection of the bands (100*100 pixels) using an image-based method. Resampling is done by going back to original raw data when creating the product after refining image coordinates with the offsets. Two types of aligned products are defined in this paper and their operational flow is described. Datasets covering different types of terrain and also viewed with different geometries are studied with extensive number of points. The band-to-band registration (BBR) accuracies are reported. The algorithm described in this paper for co-registration of Liss-4 bands is an integral part of the software package Value Added Products generation System (VAPS) for operational generation of IRS-P6 data products.

[Termes IGN] segmentation en régionsRésumé : (Auteur) The continued advancements in satellite sensor technologies have increased the number of objects that can be discriminated within satellite imagery. Effective segmentation of high resolution satellite imagery is currently a hot topic of research. Existing segmentation algorithms and applications contain many parameters and options which require the operator to select a proper set of parameters for a given data set. The setting of these parameters can be quite tedious and the same set of parameters may or may not work from one high resolution satellite image scene to the next. This paper presents a modification of a region based approach for unsupervised segmentation of high resolution satellite imagery as a solution to segmentation of land use coverage in QuickBird multispectral 2.44 m imagery. This type of segmentation is important to a variety of applications such as land use classification and urban planning. All region based segmentation approaches require a method for representing image regions/segments and judging the similarity between two given image regions/segments. In the proposed modification of this paper, region description is provided through the integration of band ratios. Region similarity measures are performed using Fuzzy Logic. The Hierarchical Split Merge Refinement (HSMR) algorithmic framework for unsupervised image segmentation is the foundation for this modification. In addition, this paper improves upon the merging and refinement processes of the HSMR algorithm. Test results demonstrate stable segmentation of land use areas across a variety of high resolution satellite images.

[Termes IGN] salinitéRésumé : (Editeur) Recognized and advocated as a powerful tool, the role of remote sensing in identifying, mapping, and monitoring soil salinity and salinization will continue to expand. This book delineates how to combine science and geospatial technologies for smart environmental management.
It explores the integrated use of image spectroscopy, electromagnetic induction (EM), and ground-penetrating radar for assessing and mapping soil salinity at local and regional levels ; reviews salt types and salinity classification schemes and the remote sensing tools and techniques for mapping and monitoring ; discusses the application of soil salinity mapping using ground-based electromagnetic induction techniques ; includes model-based integrated methods for quantitative estimation of soil salinity using hyperspectral remote sensing data ; underlines the importance of understanding the basic spectral, physical, and chemical characteristics and environmental setting of salt-affected soils in the landscape for remote sensing of salinity.
The book includes analyses of basic issues of remote detection, such as the spectral behaviour of salt types and vegetation influence, and evaluations of currently available remote sensing platforms, delineating their advantages and disadvantages for salinity mapping. The accompanying CD-ROM provides colour images that enhance the material discussed in the text. The mixture of fundamental concepts, latest technological reviews, and practical application examples makes this an ideal resource for environmental assessment and decision making.Note de contenu : Preface
