[Termes IGN] spatiotriangulationRésumé : (Auteur) The objectives of this research study was to evaluate the spatiotriangulation applied to multisensor satellite images, which enabled the simultaneous geometric processing of a large number of images and strips together to reduce the control point requirement. The spatiotriangulation is based on the three-dimensional physical models developed for multisensor images at the Canada Centre for Remote Sensing, Natural Resources Canada and on a least squares block bundle adjustment process with orbital constraints. The spatiotriangulation was applied to 49 images in six blocks (Landsat-7 ETM+, panchromatic SPOT-4 HRV, multiband ASTER, multimode radar RADARSAT-1, and ERS-1) acquired over the Rocky Mountains, Canada, from different viewing/look angles. The first results of least squares block bundle adjustments showed that the same error residuals (around 20 m) were obtained with the different image blocks whether independently or simultaneously processed. In addition to ground control points (GCPs), elevation tie points (ETPs), with a known elevation value, instead of normal tie points were used in the overlaps because the viewing/look-angle differences of overlapping images were generally small (8°). The second and most important results were related to simultaneous bundle adjustments of the largest "master" Landsat-7 block (600 km x 500 km) using 25 GCPs in the two outer strips and the smallest "slave" block(s) using no GCP but only ETPs. The errors, verified by a large number of independent check points (ICPs) in the "slave" blocks, were between 15-35 m (1.5-2 resolutions), depending on the "slave" block. However, the combined image pointing and map errors of ICPs (25-30 m) are included in these 15-35-m error results, and the internal accuracy of the blocks should, thus, be better (around one resolution). The research study demonstrated, thus, the possibility to use the largest block with a reduced number of GCPs to simultaneously adjust single image(s)/strip(s) or smallest block(s) with only ETPs, and with no degradation in the accuracy.

[Termes IGN] résolution multipleRésumé : (Auteur) Multi-observation of satellite remote-sensing provides the ability to achieve a higher spatial resolution image. Based on the relation between sensors of different spatial resolution, this paper presents a multi-observation in spatial called subpixel-shifted multi-observation, to acquire a more accurate image of higher spatial resolution than the original observations. In this kind of observation, the same area on the ground is observed repeatedly with a spatial resolution in a subpixel shifted way. All the acquired observation images are combined into a higher resolution image. This formulated as a super-resolution equation. When comparing the existing super-resolution algorithms, we find that the Iterative Back-Projection (IBP) method suggested by Peleg et al. is an appropriate and effective method for solving this problem. Based on IBP, a pratical implementation is presented. Computer experiments on remote sensing images and error analysis show its effectiveness. Some problems, such as back projection, undersampling, and fusion of observed samples, are discussed further. The resultant image from this method has both better quality and higher spatial resolution than the original observation.

This paper presents a fully automatic geometric correction system capable of georeferencing satellite images with high accuracy. An orbital prediction model, which provides initial earth locations, is combined with the proposed automatic contour-matching technique. This combination allows correcting the low-frequency error component, mainly due to timing and orbital model errors, as well as the high-frequency error component, due to variations in the spacecraft's attitude. The approach aims at exploiting the maximum reliable information in the image to guide the matching algorithm. The contour-matching process has three main steps: 1) estimation of the gradient energy map (edges) and detection of the cloudless (reliable) areas; 2) initialization of the contours positions; 3) estimation of the transformation parameters (affine model) using a contour optimization approach. Three different robust and automatic algorithms are proposed for optimization, and their main features are discussed. Finally, the performance of the three proposed algorithms is assessed using a new error estimation technique applied to Advanced Very High Resolution Radiometer (AVHRR), Sea-viewing Wide Field of view Sensor (SeaWiFS), and multisensor AVHRR-SeaWiFS imagery.

[Termes IGN] système d'information urbainRésumé : (Auteur) This paper presents how ultra high resolution remote sensing data can be used within a GIS environment for 3D city modelling and the development of urban information systems. The paper concentrates on techniques to use digital surface models (DSM's) from remotely sensed data for the creation of highly accurate digital terrain models (DTM's). DSM's can be obtained from digital stereo scanner data or from laserscanning. It can be demonstrated that DSM's from laserscanning are better suited for 3D city analysis. Using GIS techniques, however, also DSM's from stereo matching can be improved to produce highly accurate DTM's. Together with image and GIS (e.g. digital cadastral) data, these DTM's form a 3D urban information system which can be used for example for the generation of 3D simulation models that are heavily inquired for the derivation of propagation patterns (e.g., pollution, noise, radio waves).

[Termes IGN] température de surfaceRésumé : (Auteur) Multiple satellite sensors are used to analyze physical processes that determine energy fluxes and their interaction at the urban surface. The study is based on summertime microclimate analyses of the Los Angeles and Paris metropolises. The method consists of deriving some parameters governing the surface heat fluxes, constructing statistics of thermal infrared images, and using a GIS to combine them with a landcover classification from SPOTHRV multispectral images, and with data from intensive insitu experiments. The average images reveal spatial and temporal variations of land surface temperature (LST), and distinct microclimatic patterns. The combined interpretation of the statistics images and of the landcover classification shows: (i) the effect of surface physical properties, especially in downtown business and industrial districts that display heatislands larger than 7°C; (ii) the temperating influence of water; (iii) the negative correlation between afternoon land surface temperature and normalized vegetation index, which confirms the cooling effect of urban parks; (iv) the correlation between variations of surface temperature and ozone concentration at diurnal and longer time scales.
