[Termes IGN] trafic routierRésumé : (Auteur) For analyzing dynamic scenarios with many ground moving vehicles, airborne Ground Moving Target Indicator (GMTI) radar is well-suited due to its wide-area, all-weather, day/night, and real time capabilities. The generation of GMTI tracks from these data is the backbone for ground surveillance and traffic flow analysis. In case of dense target situations, missing detections and false alarms, Multi-Hypotheses Tracking (MHT) is the method at choice to solve the inherent ambiguities in the data-targets assignment problem. The resulting MHT-tracks are suited to extract road map information which is highly up-to-date and fairly precise. Moreover, their accuracy is quantitatively described. The precision of the extracted road segments can be improved significantly using smoothed or retrodicted tracks. In turn, the extracted road information is exploited for the precise tracking of succeeding road targets. The proposed, fully Bayesian approach is illustrated by a simulated example including Doppler and terrain obscuration, providing hints to the achievable road map accuracies.

[Termes IGN] SRTMRésumé : (Auteur) Après avoir décrit le contexte, les méthodes de production et certains usages scientifiques des cartes topographiques à haute résolution, nous présentons la situation actuelle et les perspectives de l'interférométrie radar, considérée comme la meilleure solution en termes de compromis entre couverture globale et précision. Après une introduction sur les aspects théoriques de cette technique – principes, limites d'emploi et capacités variées –, nous développerons son application à la topographie dont a résulté la carte globale la plus précise à ce jour : la base de données SRTM. Après une présentation du système de roue interférométrique, nous nous appuierons sur ses performances attendues pour discuter des perspectives scientifiques d'une carte topographique globale, de précision meilleure que le mètre. Nous mentionnerons également les bénéfices que d'autres domaines de l'observation spatiale, tels que l'hydrologie, peuvent retirer des produits issus des systèmes d'interférométrie radar.

[Termes IGN] interféromètrie par radar à antenne synthétiqueRésumé : (Auteur) In today's geo-technology arsenal, Interferometric Synthetic Aperture Radar (IfSAR) is quickly emerging as one of the most efficient tools for generating fast, accurate, and cost-effective digital topographic data. With its ability to penetrate clouds, rain, vegetation and even soil, IfSAR has found a unique role by being able to successfully map some of the more inaccessible and rugged equatorial rainforest areas around the world.

[Termes IGN] radargrammétrieRésumé : (Auteur) Qualified ground control points (GCPs) are crucial in the geolocation of a remotely sensed image. If a region has no published map, the geographical coordinates of GCPs must be obtained indirectly. Although these can be re-constructed from a synthetic aperture radar (SAR) image using sensor position and velocity, this conventional method does not provide accurate GCPs owing to the variable elevations of actual topography. We propose an inverse geolocation method for GCPs by SAR simulation. This improves the accuracy of extracted GCPs by accommodating topographic effects, and requires a high-resolution digital elevation model (DEM) and SAR with precise orbit data. The errors in the northing derive mainly from the imaging pulse time, and were improved by applying an azimuth time correction. In this study ERS SAR data with precise Delft orbit and shuttle radar topography mission (SRTM) DEM were used. Mean values for the planimetric distance error in the GCPs were 4.1 and 5.4 m with standard deviations of 10.6 and 16.9 m in northing and easting, respectively. The obtained GCPs were applied to an IRS image for geo-rectification, and the result was mean image positional errors of 3.6 and 2.7 m with standard deviations of 8.4 and 15.4 m in northing and easting, respectively. The root mean square errors are 9.0 and 15.3 m in northing and easting, respectively.

[Termes IGN] Polynésie françaiseRésumé : (Auteur) French Polynesia islands are located at the middle of the South Pacific Ocean. They are thus subject to a strong environmental planning leading to landscape changes as well as to the introduction of invasive species. This study comes within the framework of the global cartography and inventory of the Polynesian landscape. An AIRSAR airborne mission took place in August 2000 over the main Polynesian islands. Polarimetric SAR data are particularly adapted to the cloudy conditions generally encountered over the South Pacific Islands. Fully polarimetric data allows the analysis of a geometrical and physical point of view. Different decompositions, such as H/A/a or based on the Pauli formalism have shown their potential for such applications. In order to apply these indicators and to produce a semi-automatic cartography of the Tubuai Island, we choose to use the SVM (Support Vector Machine) as supervised classifier. These results are also compared with the Wishart classifier based on the analysis of the polarimetric coherency matrix only. As our full polarimetric data are also available in P and L bands, this study evaluates the contribution of the different wavelength. This study shown that the combination of SVM and full polarimetric data, associates with different wavelength, gives promising results.
