[Termes IGN] qualité d'imageRésumé : (auteur) Sentinel-2 is a multispectral, high-resolution, optical imaging mission, developed by the European Space Agency (ESA) in the frame of the Copernicus program of the European Commission. In cooperation with ESA, the Centre National d’Etudes Spatiales (CNES) is responsible for the image quality of the project, and will ensure the CAL/VAL commissioning phase. Sentinel-2 mission is devoted the operational monitoring of land and coastal areas, and will provide a continuity of SPOT- and Landsat-type data. Sentinel-2 will also deliver information for emergency services. Launched in 2015 and 2016, there will be a constellation of 2 satellites on a polar sun-synchronous orbit, imaging systematically terrestrial surfaces with a revisit time of 5 days, in 13 spectral bands in visible and shortwave infra-red. Therefore, multi-temporal series of images, taken under the same viewing conditions, will be available. So as to ensure for the multi-temporal registration of the products, specified to be better than 0.3 pixels at 2σ, a Global Reference Image (GRI) will be produced during the CAL/VAL period. This GRI is composed of a set of Sentinel-2 acquisitions, which geometry has been corrected by bundle block adjustment. During L1B processing, Ground Control Points will be taken between this reference image and the sentinel-2 acquisition processed and the geometric model of the image corrected, so as to ensure the good multi-temporal registration. This paper first details the production of the reference during the CALVAL period, and then details the qualification and geolocation performance assessment of the GRI. It finally presents its use in the Level-1 processing chain and gives a first assessment of the multi-temporal registration.

[Termes IGN] projection perspectiveRésumé : (Auteur) A behaviour of perspective projection which causes eccentricity in the image measurement of circular and spherical targets is discussed. While it is commonly known that flat circular targets can have a significant displacement of the elliptical image centre with respect to the true circle centre, it can also be shown that a similar effect also exists for spherical targets. Both types of target images exhibit elliptical characteristics. If measurement methods such as best-fitting ellipses are used to detect the target, the calculated ellipse centre does not correspond to the desired target centre in 3D space. This paper firstly discusses the use and measurement of circular and spherical targets. It then describes the geometrical projection model in order to demonstrate the eccentricity in image space which, based on numerical simulations, is further quantified and investigated. Finally, the resulting effect in 3D space is estimated for stereo- and multi-image intersections. It is shown that the eccentricity is larger than usually assumed, and must be compensated for in high-accuracy applications. Furthermore, spherical targets do not display better results than circular targets.

[Termes IGN] point d'appuiRésumé : (Auteur) As a generic sensor model, the rational function model (RFM) has been widely used in the geometric processing of optical images, but its application to synthetic aperture radar (SAR) datasets has not been developed sufficiently. In this paper a thorough study of the RFM-based bundle adjustment for the simultaneous positioning of multi-sensor spaceborne SAR imagery is made. Different control point layouts are designed to analyse its accuracy, and block adjustments based on a rigorous model are compared with the RFM. Experiments show that the RFM can attain a similar positional accuracy to the rigorous model and, when ground control points are sparse, the RFM is more stable.

[Termes IGN] test de performanceRésumé : (Auteur) The increasing role of pushbroom cameras in large photogrammetric projects has fostered international interest in achieving a sound knowledge of this device. In addition, the classic software tools, implemented for frame cameras, need to be adapted to cope with modified aerial triangulation and self-calibration procedures. This contribution presents the results obtained from the geometrical analysis and self-calibration of the second-generation pushbroom ADS40 camera, the SH52. For this purpose, a testfield was designed and built on the outskirts of Ávila, Spain and two blocks, flown at different heights, were imaged. A wide network of well-defined control and check points was observed in order to provide a thorough assessment of the accuracy and reliability of the camera. Empirical analysis of a variety of models within aerial triangulation as well as the use of internal camera parameters has led to an evaluation of the camera's performance in a real-life environment.

[Termes IGN] point d'appuiRésumé : (Auteur) A large amount of aerial photographs were acquired early 1900s for various purposes. These aerial photographs provide valuable baseline data for a variety of environmental studies. To be used for analysis together with other data, these photographs need to be referenced to a ground coordinate system. Often large topographical variations in photo ground coverage demand these photographs be orthorectified using photogrammetric methods for acceptable mapping accuracy. However, camera models for these historical photographs are usually unavailable. Additionally, land-cover change over the years makes it a great challenge to collect accurate control points for calculating camera models. This study investigated the rational function model to orthorectify historical aerial photographs. The analysis results suggest that while the linear, the 2nd order, and the 3rd order BFMs are all able to closely approximate the rigorous frame camera model, the linear RFM is optimal in representing imaging geometries of historical photographs.
