[Vedettes matières IGN] Ecologie forestièreRésumé : (auteur) Here we present a phytosociological analysis of the forest biodiversity of the Gargano Peninsula, located in the eastern part of the Italian peninsula. As well as presenting all of the woods described and classified in terms of their phytosociology to date, we present the following plant associations that are mainly distributed in the low supratemperate and upper mesotemperate bioclimatic belts: Carici halleranae-Ostryetum carpinifoliae ass. nova; Polysticho setiferi-Ostryetum carpinifoliae ass. nova; Rubio peregrinae-Aceretum campestris; Physospermo verticillati-Quercetum cerris; Doronico orientalis-Carpinetum betuli; Pulmonario apenninae-Aceretum neapolitani ass. nova; Teucrio siculi-Aceretum campestris ass. nova; Festuco exaltatae-Tilietum platyphylli ass. nova; Phyllitido scolopendri-Lauretum nobilis ass. nova and Aremonio agrimonioidis-Fagetum sylvaticae ass. nova. For these, subassociations and variants are described. The syntaxonomic classification allows the description of two new syntaxa at the heirarchical level of alliances: Physospermo verticillati-Quercion cerris, all. nova, the southern Italian substitute for the alliance Erythronio-Carpinion, which includes the southern mesophilous Turkey oak, European hornbeam, Neapolitan maple and field maple woods; Lauro nobilis-Tilion platyphylli all. nova, the southern substitute for the alliance Tilio platyphylli-Acerion pseudoplatani.

[Termes IGN] semis de pointsRésumé : (Auteur) A lidar filtering technique is used to differentiate on-terrain points and off-terrain points from a cloud of 3D point data collected by a lidar system. A major issue of concern in this low-level filter is to design a methodology to ensure a continual adaptation to variations of terrain slopes and object scales. In this paper, a new lidar filtering technique which hierarchically fragments lidar data into piecewise planar terrain models is introduced. Once a number of hypothetical planar terrain models are generated to fit the terrain surface of the underlying area, the optimal terrain model to produce the minimum labelling errors is determined based on minimum description length (MDL) principles. This hypothesis-verification optimisation is achieved in a coarse-to-fine strategy by which the entire terrain surface is incrementally reconstructed by increasing the number of planar terrain models fitted. The proposed technique was successfully applied to a digital surface model provided within an OEEPE lidar trial, showing 0·94% of Type I errors and 6·75% of Type II errors compared to manually classified reference data.

[Termes IGN] réflectanceRésumé : (Auteur) An image-based 3D surface reconstruction method based on simultaneous evaluation of intensity and polarisation features (shape from photopolarimetric reflectance) and its combination with absolute depth data is introduced in this article. The proposed technique is based on the analysis of single or multiple intensity and polarisation images. To compute the surface gradients, we present a global optimisation method based on a variational framework and a local optimisation method based on solving a set of non-linear equations individually for each image pixel. These approaches are suitable for strongly non-Lambertian surfaces and those of diffuse reflectance behaviour and can also be adapted to surfaces of non-uniform albedo. We describe how independently measured absolute depth data is integrated into the shape from photopolarimetric reflectance framework in order to increase the accuracy of the 3D reconstruction result. In this context we concentrate on dense but noisy depth data obtained by depth from defocus and on sparse but accurate depth data obtained by stereo or structure from motion analysis. We show that depth from defocus information should preferentially be used for initialising the optimisation schemes for the surface gradients. For integration of sparse depth information, we suggest an optimisation scheme that simultaneously adapts the surface gradients to the measured intensity and polarisation data and to the surface slopes implied by depth differences between pairs of depth points. In principle, arbitrary sources of depth information are possible in the presented framework. Experiments on synthetic and on real-world data reveal that while depth from defocus is especially helpful for providing an initial estimate of the surface gradients and the albedo in the absence of a-priori knowledge, integration of stereo or structure from motion information significantly increases the 3D reconstruction accuracy. In our real-world experiments, we regard the scenarios of 3D reconstruction of raw forged iron surfaces in the domain of industrial quality inspection and the generation of a digital elevation model of a section of the lunar surface in the context of space-based planetary exploration.

[Termes IGN] Yunnan (Chine)Résumé : (Auteur) Mapping dominant vegetation communities is important work for vegetation scientists. It is very difficult to map dominant vegetation communities using multispectral remote sensing data only, especially in mountain areas. However plant community data contain useful information about the relationships between plant communities and their environment. In this paper, plant community data are linked with remote sensing to map vegetation communities. The Bayesian soft classifier was used to produce posterior probability images for each class. These images were used to calculate the prior probabilities. One hundred and eighty plant plots at Meili Snow Mountain, Yunnan Province, China were used to characterize the vegetation distribution for each class along altitude gradients. Then, the frequencies were used to modify the prior probabilities of each class. After stratification in a vegetation part and a non-vegetation part, a maximum-likelihood classification with equal prior probabilities was conducted, yielding an overall accuracy of 82.1% and a kappa accuracy of 0.797. Maximum-likelihood classification with modified prior probabilities in the vegetation part, conducted with a conventional maximum-likelihood classification for the non-vegetation part, yielded an overall accuracy of 87.7%, and a kappa accuracy of 0.861.
