L’une des applications de ce traitement peut être l’étude sociologique, et notamment la mesure de la gentrification, processus par lequel des classes aisées s’installent dans des quartiers historiquement moins favorisés. En effet, ce phénomène se caractérise souvent par une modification de l’aspect des habitations, qui peut être détectée par un modèle de classification. Ce projet consiste à traiter toutes les étapes de cette classification, du téléchargement de l’imagerie urbaine jusqu’à la cartographie du phénomène étudié et peut être adapté à la qualification de n’importe quel phénomène urbain (accessibilité pour les piétons, structure des bâtiments…). Je me suis en particulier attaché à l’étape de la conception du modèle, en explorant notamment des techniques innovantes basées sur des réseaux de neurones convolutifs et dont les résultats sont prometteurs. Le travail a été effectué sur l’unité urbaine de la ville d’Ottawa au Canada.

[Vedettes matières IGN] Ecologie forestièreRésumé : (auteur) Large volcanic eruptions can alter forest plant communities through a variety of mechanisms, including direct destruction of forests and changes to forest soils through tephra (aerially transported volcanic ejecta) deposits. While many studies have examined succession following direct destruction of forests, impacts to plant communities through tephra effects are less obvious, especially where the tephra depth is less than plant height. We used a 33-year experiment in an old growth forest that received shallow tephra deposition in the 1980 eruption of Mount St. Helens (WA, USA), to examine plant communities. We determined if community differences between plots with and without tephra: (1) were detectable, and (2) changed over time. We found that plant communities differed significantly between plots with and without tephra after 33 years. Further, differences were stronger after 33 years than at two years following the eruption. Species richness increased over time in both plots with and without tephra, but live cover was largely stable after two years. Nevertheless, communities shifted in different directions over time, where the changes in species composition and abundance immediately following tephra deposition were inconsistent with net changes that occurred over 30 years afterwards. These results suggest that widespread and apparently minor deposits of tephra, usually interpreted to be of transient importance if any, may induce long-term modifications of understory plant communities.

[Termes IGN] traitement de données localiséesRésumé : (auteur) Les modèles numériques d’altitudes (MNA) font partie intégrante de la modélisation des inondations. Les données MNA à haute résolution ne sont pas toujours disponibles ou abordables pour les collectivités et ainsi d’autres sources de données altimétriques sont examinées. Bien que la précision de certaines de ces sources ait été rigoureusement vérifiée (p. ex., SRTM, ASTER), d’autres, telles que les API REST du modèle numérique d’élévation du Canada (MNÉC) de Ressources naturelles Canada et les API REST d’élévations de Google et Bing, n’ont pas encore été correctement évaluées. Les détails concernant la source d’acquisition et la précision sont souvent non publiés pour les API. Pour inclure ces données dans les applications géospatiales afin d’évaluer l’incertitude et la réduire, la fusion des données est examinée. Ainsi, cet article présente une nouvelle méthode de fusion des données altimétriques. La nouvelle méthode intègre les concepts de partitionnement des données et de pondération inverse à la distance (PID) dans le calcul d’une nouvelle surface altimétrique fusionnée. Les résultats des MNA individuels et des MNA fusionnés sont comparés à une surface LiDAR (détection et télémétrie par ondes lumineuses) à haute résolution et aux cartes des inondations pour deux zones d’étude au Nouveau-Brunswick. La comparaison des surfaces individuelles avec celle du LiDAR conclut que les résultats respectent leurs spécifications de précision affichées, les données de Bing calculant les plus petits biais moyens et le MNÉC les plus petits écarts types. La fusion des trois surfaces au moyen de la méthode proposée augmente la corrélation et minimise l’écart type et le biais moyen lorsqu’on la compare au LiDAR, indépendamment du terrain, produisant ainsi un MNA plus précis.

[Termes IGN] teneur en azoteRésumé : (Auteur) Real-time, nondestructive monitoring of crop nitrogen (N) status is a critical factor for precision N management during wheat production. Over a 3-year period, we analyzed different wheat cultivars grown under different experimental conditions in China and Canada and studied the effects of viewing angle on the relationships between various vegetation indices (VIs) and leaf nitrogen concentration (LNC) using hyperspectral data from 11 field experiments. The objective was to improve the prediction accuracy by minimizing the effects of viewing angle on LNC estimation to construct a novel vegetation index (VI) for use under different experimental conditions. We examined the stability of previously reported optimum VIs obtained from 13 traditional indices for estimating LNC at 13 viewing zenith angles (VZAs) in the solar principal plane (SPP). Backscattering direction showed better index performance than forward scattering direction. Red-edge VIs including modified normalized difference vegetation index (mND705), ratio index within the red edge region (RI-1dB) and normalized difference red edge index (NDRE) were highly correlated with LNC, as confirmed by high R2 determination coefficients. However, these common VIs tended to saturation, as the relationships strongly depended on experimental conditions. To overcome the influence of VZA on VIs, the chlorophyll- and LNC-sensitive NDRE index was divided by the floating-position water band index (FWBI) to generate the integrated narrow-band vegetation index. The highest correlation between the novel NDRE/FWBI parameter and LNC (R2 = 0.852) occurred at −10°, while the lowest correlation (R2 = 0.745) occurred at 60°. NDRE/FWBI was more highly correlated with LNC than existing commonly used VIs at an identical viewing zenith angle. Upon further analysis of angle combinations, our novel VI exhibited the best performance, with the best prediction accuracy at 0° to −20° (R2 = 0.838, RMSE = 0.360) and relatively good accuracy at 0° to −30° (R2 = 0.835, RMSE = 0.366). As it is possible to monitor plant N status over a wide range of angles using portable spectrometers, viewing angles of as much as 0° to −30° are common. Consequently, we developed a united model across angles of 0° to −30° to reduce the effects of viewing angle on LNC prediction in wheat. The proposed combined NDRE/FWBI parameter, designated the wide-angle-adaptability nitrogen index (WANI), is superior for estimating LNC in wheat on a regional scale in China and Canada.

[Termes IGN] varianceRésumé : (Auteur) One of the challenges for geoid determination is the combination of heterogeneous gravity data. Because of the distinctive spectral content of different data sets, spectral combination is a suitable candidate for its solution. The key to have a successful combination is to determine the proper spectral weights, or the error degree variances of each data set. In this paper, the error degree variances of terrestrial and airborne gravity data at low degrees are estimated by the aid of a satellite gravity model using harmonic analysis. For higher degrees, the error covariances are estimated from local gravity data first, and then used to compute the error degree variances. The white and colored noise models are also used to estimate the error degree variances of local gravity data for comparisons. Based on the error degree variances, the spectral weights of satellite gravity models, terrestrial and airborne gravity data are determined and applied for geoid computation in Texas area. The computed gravimetric geoid models are tested against an independent, highly accurate geoid profile of the Geoid Slope Validation Survey 2011 (GSVS11). The geoid computed by combining satellite gravity model GOCO03S and terrestrial (land and DTU13 altimetric) gravity data agrees with GSVS11 to ±1.1 cm in terms of standard deviation along a line of 325 km. After incorporating the airborne gravity data collected at 11 km altitude, the standard deviation is reduced to ±0.8 cm. Numerical tests demonstrate the feasibility of spectral combination in geoid computation and the contribution of airborne gravity in an area of high quality terrestrial gravity data. Using the GSVS11 data and the spectral combination, the degree of correctness of the error spectra and the quality of satellite gravity models can also be revealed.
