[Termes IGN] système d'information géographiqueRésumé : (Auteur) L’érosion hydrique est une forme de dégradation qui se traduit par le décapage des éléments minéraux et organiques du sol. Sous l’action des agents météoriques (pluie, vent) ce phénomène mondial, l’érosion, affecte la productivité des terres agricoles. L’absence d’un couvert végétal protecteur et les précipitations intenses ont fait du bassin du Litani une région vulnérable à l’érosion hydrique. L’absence de données climatiques nous a amenés à dresser la carte de l’aléa érosion en nous appuyant sur une méthode qualitative qui combine, à l’aide d’un SIG, les facteurs tels que l’érosivité du sol, la perméabilité des roches, le mode d’occupation du sol et l’intensité des précipitations. Les résultats montrent que l’aléa fort s’étale sur 39,3 % de la région d’étude. D’après la validation de terrain, la fiabilité est estimée à 80 % en se basant sur le décapage du sol, la taille des glissements de terrain et la profondeur des déchaussements de racines. Le modèle utilisé peut être applicable à d’autres régions similaires de Méditerranée.

[Vedettes matières IGN] GéovisualisationRésumé : (Auteur) De nombreuses études et recherches visent à mieux connaitre les phénomènes de type pollution ou météo. Les champs de valeur représentant ces phénomènes peuvent être visualisés sur des outils de visualisation scientifiques qui ne disposent pas de la richesse de symbolisation propre aux SIGs, notamment pour le géoréférencement et pour la représentation des objets vectoriels décrivant l’espace support. La représentation sous forme raster sur SIG est possible mais limitée. Pourtant au niveau scientifique il est important de pouvoir co-visualiser les champs dans leur contexte géographique pour mieux les analyser et faire des hypothèses sur les interactions entre un phénomène et l’espace support. Dans ce papier nous proposons de créer des objets graphiques spécifiques permettant de visualiser des champs de valeur à différents niveaux de détail et sur différents objets de l’espace support. Les objets graphiques de type plan mettent en valeur la continuité du phénomène et se voient par transparence avec les autres objets alors que les objets de type grille permettent de voir le champ et les autres objets décrivant l’espace. Les données peuvent aussi être projetées sur des objets vectoriels particuliers de l’espace support. Nous proposons également d’utiliser des symboles surfaciques et non ponctuels afin de mieux résister aux opérations de zoom et de dézoom. Nous proposons un modèle de données dédié à la représentation graphique des données de type phénomène que nous illustrons à partir de données décrivant un flux et une pollution dans une canalisation d’eau et des données météorologiques urbaines. Dans ce papier nous ne traitons pas de la représentation de la dynamique en tant que tel mais nous proposons une meilleure représentation graphique de chaque état décrivant un phénomène.

[Termes IGN] zone semi-arideRésumé : (Auteur) The use of land surface temperature (LST) for monitoring the consumption and water status of crops requires data at fine spatial and temporal resolutions. Unfortunately, the current spaceborne thermal sensors provide data at either high temporal (e.g. MODIS: Moderate Resolution Imaging Spectro-radiometer) or high spatial (e.g. Landsat) resolution separately. Disaggregating low spatial resolution (LR) LST data using ancillary data available at high spatio-temporal resolution could compensate for the lack of high spatial resolution (HR) LST observations. Existing LST downscaling approaches generally rely on the fractional green vegetation cover (fgv) derived from HR reflectances but they do not take into account the soil water availability to explain the spatial variability in LST at HR. In this context, a new method is developed to disaggregate kilometric MODIS LST at 100 m resolution by including the Sentinel-1 (S-1) backscatter, which is indirectly linked to surface soil moisture, in addition to the Landsat-7 and Landsat-8 (L-7 & L-8) reflectances. The approach is tested over two different sites – an 8 km by 8 km irrigated crop area named “R3” and a 12 km by 12 km rainfed area named “Sidi Rahal” in central Morocco (Marrakech) – on the seven dates when S-1, and L-7 or L-8 acquisitions coincide with a one-day precision during the 2015–2016 growing season. The downscaling methods are applied to the 1 km resolution MODIS-Terra LST data, and their performance is assessed by comparing the 100 m disaggregated LST to Landsat LST in three cases: no disaggregation, disaggregation using Landsat fgv only, disaggregation using both Landsat fgv and S-1 backscatter. When including fgv only in the disaggregation procedure, the mean root mean square error in LST decreases from 4.20 to 3.60 °C and the mean correlation coefficient (R) increases from 0.45 to 0.69 compared to the non-disaggregated case within R3. The new methodology including the S-1 backscatter as input to the disaggregation is found to be systematically more accurate on the available dates with a disaggregation mean error decreasing to 3.35 °C and a mean R increasing to 0.75.

[Vedettes matières IGN] Inventaire forestierRésumé : (auteur) Understanding the impacts of large-scale disturbances on forest conditions is necessary to support forest management, planning, and policy decision making. National forest inventories (NFIs) are an important information source that provide consistent data encompassing large areas, covering all ownerships, and extending through time. Here we compare how temporal aggregation approaches with NFI data affects estimates of standing dead trees as these respond to extreme disturbance events. East Texas was selected for this study owing to the occurrence of three significant disturbance events in a short span: Hurricane Rita in 2005, Hurricane Ike in 2008, and a historic drought in 2011. Wide-spread tree damage and mortality were reported after each disturbance and estimates of standing dead trees were used as the inventory variable for assessment. In the NFI of the US, the plot network is systematically divided into panels and one panel is measured each year. A measurement cycle is completed when all panels have been measured, which varies between 5 and 10 years depending on the region. Using the standard estimation approach of the US NFI, we computed population estimates using data from the full set of panels (FSP), multiple sets of panels (MSP), and single set of panels (SSP). For estimation, a single plot observation is computed from the most recent measurement of the plot that does not exceed the estimate year. Because one panel is measured per year, FSP and MSP estimates will necessarily consist of plot observations whose measurements were collected over a number of years. The SSP estimate is computed from one panel and thus all the plot observations are based on measurements collected over one year. We found that interpretations of disturbance event impacts varied depending on which sets of estimates were considered. All sets of estimates suggested a large and significant drought impact. However, differences existed among the estimates in the timing and magnitude of the impacts. The FSP estimates showed clear lag bias and smoothing of trends relative to the SSP estimates. MSP estimates were intermediate between FSP and SSP estimates. Differences in Hurricane Rita impacts were also observed between sets of estimates. Evidence of a net impact on standing dead trees following Hurricane Ike was weak among all sets of estimates. Given the potential for lag bias and smoothing, we recommend that SSP and MSP estimates be considered along with FSP estimates in assessments of large-scale disturbance impacts on forest conditions.

[Vedettes matières IGN] Traitement de données GNSSRésumé : (Auteur) To access the full capabilities of multi-frequency signals from the modernized GPS, GLONASS and newly deployed BDS, Galileo, the undifferenced and uncombined observable model in which the individual signal of each frequency is treated as independent observable has drawn increasing interest in GNSS community. The ionosphere delay is the major issue in the undifferenced and uncombined observable model. Though several ionosphere delay parameterization approaches have been promoted, we argue that the functional model with only deterministic characteristic may not follow the irregular spatial and temporal variations. On the contrary, when the ionosphere delay is estimated as random walk or even white noise with only stochastic characteristic, the ionosphere terms turn out to be non-estimable or not sensitive to their absolute value. In the authors’ previous study, we have developed the deterministic plus stochastic ionosphere model, denoted as DESIGN, in which the deterministic part expressed with second-order polynomial is estimated as piece-wise constant over 5 min and the stochastic part is estimated as random walk with constrains derived based on statistics of 4 weeks data in 2010. In this contribution, we further model the deterministic part with Fourier series and update the variogram of the stochastic part accordingly based on two-year data collected by about 150 stations. From the statistic studies, it is concluded that the main frequency components are identical for different coefficients, different stations, as well as different ionosphere activity status, but with varying amplitude. Thus, in the Fourier series expression of the deterministic part, we fix the frequency and estimate the amplitude as daily constant unknowns. Concerning the stochastic component, the variation of variogram is both, geomagnetic latitude and ionosphere activity status dependent. Thus, we use the Gaussian function and Epstein function to model the variation of geomagnetic latitude and ionosphere activity status, respectively. Based on the undifferenced and uncombined observable model with ionosphere constrained with DESIGN, both dual-frequency and single-frequency PPP are carried out to demonstrate its efficiency with three-month data collected in 2010, 2014, and 2017 with different ionosphere activity status. The experimental results suggest that compared with ionosphere-free model and our previous method, the averaged 3D improvement of our new method is 17.8 and 7.6% for dual-frequency PPP, respectively. While for single-frequency PPP, the averaged 3D improvement is 37.0 and 14%, respectively.
