[Termes IGN] tâche claireRésumé : (Auteur) We have studied the geographic position of several high-resolution spotlight TSX images by investigating the location of deployed radar corner reflectors. Results show that the geolocation accuracy is better than the resolution cell in both azimuth and range directions. The same corner reflectors as well as distinct points on buildings are used to estimate the absolute height from stereo viewing spotlight TSX images to within a few decimeters accuracy.

[Termes IGN] rétrodiffusionRésumé : (Auteur) Global backscatter data can be used for accurate synthetic aperture radar (SAR) performance estimation and optimizing instrument settings for SAR systems, e.g. the TerraSAR-X mission (TSM) and the TanDEM-X mission (TDM). The goal of this work is the generation of X-band backscatter maps by mosaicking images acquired by the TSM. An algorithm that allows the estimation of the on-ground backscatter, for any required polarization and incidence angle from the available data, is implemented. In this paper, the backscatter map generation algorithm is presented, together with the first results, obtained from the TSX-1 data. The validity of the interpolation models is also discussed, as they will form the basis for a future global statistical analysis and modeling of backscatter behavior in X-band SAR data.

[Termes IGN] modèle numérique de terrainRésumé : (Auteur) With the successful launch of the German radar satellite TanDEM-X on june 21st, 2010, a new era of global digital elevation information provision has commenced. Together with TerraSAR-X, TanDEM-X forms a high-precision radar interferometer acquiring the data basis for a global homogeneous Digital Elevation Model of unprecedented quality, accuracy, and coverage. This unique dataset will be available for the entire land surface of the Earth from 2014 onwards.

[Termes IGN] zone urbaineRésumé : (Auteur) Orthorectification of satellite data is one of the most important pre-processing steps for application oriented evaluations and for image data input into Geographic Information Systems. Although high- and very high-resolution optical data can be rectified without ground control points (GCPs) using an underlying digital elevation model (DEM) to positional root mean square errors (RMSEs) between 3 m and several hundred meters (depending on the satellite), there is still need for ground control with higher precision to reach lower RMSE values for the orthoimages. The very high geometric accuracy of geocoded data of the TerraSAR-X satellite has been shown in several investigations. This is due to the fact that the SAR antenna measures distances which are mainly dependent on the terrain height and the position of the satellite. The latter can be measured with high precision, whereas the satellite attitude need not be known exactly. If the used DEM is of high accuracy, the resulting geocoded SAR data are very precise in their geolocation. This precision can be exploited to improve the orientation knowledge and thereby the geometric accuracy of the rectified optical satellite data. The challenge is to match two kinds of image data, which exhibit very different geometric and radiometric properties. Simple correlation techniques do not work and the goal is to develop a robust method which works even for urban areas, including radar shadows, layover and foreshortening effects. First the optical data have to be rectified with the available interior and exterior orientation data or using rational polynomial coefficients (RPCs). From this approximation, the technique used is the measurement of small identical areas in the optical and radar images by automatic image matching, using a newly developed adapted mutual information procedure followed by an estimation of correction terms for the exterior orientation or the RPC coefficients. The matching areas are selected randomly from a regular grid covering the whole imagery. By adjustment calculations, parameters from falsely matched areas can be eliminated and optimal improvement parameters are found. The original optical data are orthorectified again using the delivered metadata together with these corrections and the available DEM. As proof of method the orthorectified data from IKONOS and ALOS-PRISM sensors are compared with conventional ground control information from high-precision orthoimage maps of the German Cartographic Survey. The results show that this method is robust, even for urban areas. Although the resulting RMSE values are in the order of 2–6 m, the advantage is that this result can be reached even for optical sensors which do not exhibit low RMSE values without using manual GCP measurements.
