[Termes IGN] plateformeRésumé : (Auteur) This paper provides an overview of hyperspectral applications and data requirements gathered by an ad-hoc group of French scientists and Defence users. This group known by the acronym GSH (Groupe de Synthese sur I'Hyperspectral) has addressed clear and detailed technical requirements for a high spatial resolution hyperspectral mission on the following themes: study of vegetation, coastal and inland water ecosystems, geosciences, urban environment, atmospheric studies, security, and Defence. The synthesis of these requirements substantially helped to set up consolidated space-based system requirements (i.e. mission requirements) in terms of spectral domain, spectral resolution, signal-to-noise ratio, spatial resolution, swath and revisiting period, which revealed the main key drivers for the design of a very innovative hyperspectral space instrument. HYPXIM is a new-generation hyperspectral concept which meets the needs of a wide community of users in the world. During the phase 0, CNES with the support of industry (Astrium et Thales Alenia Space) has compared two different scenarii. The first scenario, named HYPXIM-C, aims at finding out the highest possible resolution level (15 m) achievable using a microsatellite platform, whereas the goals of the second scenario, called HYPXIM-P, are to reach a higher spatial resolution (8 m), and to provide a TIR hyperspectral capability. The HYPXIM phase A was recently decided and focused on the most performing concept, but without TIR capabilities. The challenges for the selected HYPXIM mission were to design an agil high resolution spectroimager on a mini-satellite. Preliminary studies with industrial support show that this challenge can be taken to space around 2020/21 depending on the development of critical technologies (like specific detectors). Expected lifetime in orbit is 10 years, including end-of-life operations.

[Termes IGN] stéréoscopieRésumé : (Auteur) The successful launch of Pleiades 1A on the night of 16th to 17th December 2011 is a long-awaited milestone for the users of satellite images. This satellite is operated in a dual-purpose Earth observation system providing high resolution optical images to satisfy the new mission requirements of both defence users and civilian stakeholders (institutions, scientists, etc.). The optical mission consists in Earth optical observation composed of 0.7 m nadir resolution for the panchromatic band and 2.8 m nadir resolution for the four multi-spectral bands. The image swath is about 20 km. The system is based on the use of a set of newly developed European technologies to feature the satellite. Thanks to the huge satellite agility obtained with control momentum gyros as actuators, the optical system also delivers instantaneous stereo images, under different stereoscopic conditions, and mosaic images, issued from along the track thus enlarging the field of view. The system commissioning phase that ran from the launch until march 2012 was dedicated to checking every single piece of equipment in the satellite and every system function, in order to characterize, tune and calibrate all the models that are required to assess the expected behaviour and performances. The thematic assessment of Pleiades data had been prepared since 2007 in the framework of the ORFEO program, gathering many user organisations (IGN, BRGM, INRA, CNRS, Cemagref, CIRAD) and service providers (Astrium Geo-lnformation Services, ACRI, SERTIT).

[Termes IGN] superposition d'imagesRésumé : (Auteur) A large amount high-resolution satellite imagery (hrsi) has been available in the commercial market because of its value in creating accurate base maps for various applications. As massive amounts of HRSI are acquired globally by satellites with short revisit times, automated but accurate georegistration is still required despite advances in precise orbit tracking and estimation. Motivated by the attractive properties of airborne lidar data, such as their high resolu-tion and accuracy, this study proposes a new automated method for refining the HRSI with rational polynomial coefficients (RPCs) using airborne lidar information. By projecting the lidar intensity return into the HRSI space, the image matching complexity is reduced to a simple, 2D case. The true challenge is in overcoming the difference between the HRSI and the lidar intensity return to allow for reliable matching. To this end, this paper proposes a new method based on simple relative edge cross correlation (RECC) with a screening method to prevent false matching. To make the approach more robust, data snooping was added for a final detection of outliers. Experiments were performed using three Kompsat-2 images and the potential of the approach.

[Termes IGN] modèle numérique de surfaceRésumé : (Auteur) Built-up environments are extremely complex for 3D surface modelling purposes. The main distortions that hamper 3D reconstruction from 2D imagery are image dissimilarities, concealed areas, shadows, height discontinuities and discrepancies between smooth terrain and man-made features. A methodology is proposed to improve automatic photogrammetric extraction of an urban surface model from high resolution satellite imagery with the emphasis on strategies to reduce the effects of the cited distortions and to make image matching more robust. Instead of a “standard” stereoscopic approach, a digital surface model is derived from tri-stereoscopic satellite imagery. This is based on an extensive multi-image matching strategy that fully benefits from the geometric and radiometric information contained in the three images. The bundled triplet consists of an IKONOS along-track pair and an additional near-nadir IKONOS image. For the tri-stereoscopic study a densely built-up area, extending from the centre of Istanbul to the urban fringe, is selected. The accuracy of the model extracted from the IKONOS triplet, as well as the model extracted from only the along-track stereopair, are assessed by comparison with 3D check points and 3D building vector data.

[Termes IGN] réseau sémantiqueRésumé : (Auteur) The usefulness and acceptance of geo-information systems are mainly depends on the quality of the underlying geo-data. This paper describes a novel system for semi-automatic quality control of existing topographic geo-spatial data via automatic image analysis. The goal is to reduce the manual effort for quality control of a GIS database to a minimum. The core of the system is a semantic network in which different image analysis operators can be included. The image analysis operators are created for specific applications, i.e., the quality control of specific object classes which are most relevant. Images which can be used in the system are aerial images, high-resolution satellite imagery, and low-resolution satellite imagery. A prototype of the system has been in use for several years at public mapping organizations. From the experience gained during this time, we give a detailed report on the system performance and an evaluation of the results.
