[Termes IGN] précision géométrique (imagerie)Résumé : (Auteur) Rigorous satellite and airborne sensor models are nowadays commonly used to set accurate mapping applications trough accurate geodesy and ground cartography. Last decade improvement have enlightened the cartography community to the performance of such physical models to improve the map accuracy to a metric -or better- cartographic accuracy limit depending on the sensor type, math model robustness, ground control point quality and error dispersion control throughout the block adjustment of large image sets. Such operations allow to produce maps from high and very high resolutions sensors, optical and SAR in different contexts and for multiples applications such as urban mapping, rural land registration, precision farming... Nevertheless, this methodology still involves some limits in the case this is wether partly farther not possible to obtain a reliable enough positional ground reference associated to the mapping project. Various orbital and ground geodetic location systems are now commonly used among earth observation satellites, such as GPS and DORIS. Some recent experimental and operational works that uses an original methodology still based on a rigorous sensor model and the support of a robust block adjustment have proven the ability to recombine series of sensor images on several orbits or flight paths. These tied together with the preservation of the sensor model, its refined earth position and support of a reliable digital elevation model, allow to georeference image blocks based on the internal airborne / spaceborne ground coordinates processed by the operator trough the satellite positioning system. Such refined ground controls and a physical rigorous sensor model association now enables image block georeferencing to the ground with a final accuracy compatible enough with mapping standards even without reliable ground planimetric reference (GCP). Several mapping tests controlled with various aerial, optical and SAR satellite sensors, such as Ikonos, Quickbird, Orbview-3, Envisat ASAR and SPOT 5, the Vexcel UltraCAM-D digital airborne camera along with IMU and GPS, as well as ground reference sources have proven that such methodology and resulting processed imagery makes possible the use of high and very high resolution satellite imagery for a much wider application field, such as marine cartography, accurately geo-positioned defense imagery recognition on remote or not accessible locations. Our scope is precisely to determine which methodology used among those described sensors would apply to which case with error dispersion control capability or not, to validate such a mapping methodology and process, and finally foresee the possible applications field for the mapping industry.

[Termes IGN] qualité géométrique (image)Résumé : (Auteur) This paper describes a geometric evaluation of the photogrammetric workflow resulting from an experimental aerial survey performed using a Leica Airborne Digital Sensor (ADS40) system. Imagery of a 13 km2 study area in the United Kingdom was captured using an ADS40. The study area was flown with the ADS40 at four different altitudes with resulting imagery at ground sampled distances of 15, 20, 25 and 30 cm. Ground points, comprising natural features distributed throughout the study area, were surveyed using GPS methods. In addition, RC30 film imagery and data from a lidar survey conducted using an Optech ALTM 2050 airborne laser scanner was also available for use in validation. The ADS40 imagery of the study area was processed using standard commercial software and a number of tests were conducted to geometrically assess the photogrammetric performance of imagery from the sensor at various stages throughout the photogrammetric workflow. Experiments examined the influence of ground control points (GCPs) in bundle block adjustment and the performance of digital elevation models (DEMs) resulting from the processing of ADS40 imagery. This independent research has permitted a series of initial conclusions to be drawn and preliminary recommendations to be made for optimum deployment of the ADS40 sensor under certain operational conditions. For example, it is shown that, despite advances made in direct positioning and orientation using integrated satellite and inertial surveying, the importing of GCPs into the block adjustment process remains a critical issue influencing the achievable accuracy during photogrammetric measurement.

[Termes IGN] point d'appuiRésumé : (Auteur) The adoption of rational functions as a preferred sensor orientation model for narrow field of view line scanner imagery accompanied the introduction of commercial high-resolution satellite imagery (HRSI) at the turn of the millennium. This paper reviews the developments in ground point determination from HRSI via the model of terrain independent rational polynomial coefficients (RPCs). A brief mathematical background to rational functions is first presented, along with a review of the models for generating RPCs from a rigorous sensor orientation, and for geopositioning via either forward intersection or monoplotting. The concept of RPC block adjustment with compensation for exterior orientation biases is then discussed, as is the means to enhance the original RPCs through a bias correction procedure. The potential for RPC block adjustment to yield sub-pixel geopositioning accuracy from HRSI is illustrated using results from experimental testing with two Quickbird stereo image pairs and three multi-image IKONOS blocks. Finally, error propagation issues in RPC block adjustment of HRSI are considered.

[Termes IGN] stéréoscopieRésumé : (Auteur) HRS instrument on board of SPOT 5 allows acquisition of stereoscopic pairs in a single pass. Its final purpose is to provide the worldwide database of Digital Terrain Models and Orthoimages, called ReferenceSD®, with no use of ground control points and a horizontal location specified as 16 m for 90% of the points. The stake is not only to fulfil the HRS' location specification of 50 m in root mean square but to obtain a location performance as best as possible and to check that the instrument can cope with the realisation of the ReferenceSD® database. That's why HRS has been the subject of specific attention even after the end of SPOT 5 in-flight commissioning phase.
This comprehensive paper summarizes the steps jointly taken by CNES, IGN, Spot Image and HRS end-users to calibrate, monitor and validate the HRS image accuracy as well as the accuracy of the final DEM products. First, an overview of HRS on SPOT 5 will be given, with a specific attention paid to the instrument geometry and rigorous sensor model available through ancillary data given with the images. Then, methods and means used by the French Space Agency (CNES) and the French Mapping Agency (IGN) to reach the objectives will be described and the final accuracy reached will be given. It concems: 1-- calibration and monitoring of the HRS geometrical parameters, and the several on board improvements brought to the satellite by CNES to improve the location accuracy at the single pair level (i.e. no tie points nor ground control points used); 2-- the HRS block adjustment model calibration and the evaluation performed by IGN at the stereo pair level (i.e with tie points used within the pair) and block level (with tie points used between different HRS strips). Finally, the article deals with several comparisons of HRS DEM's against available DEMs (eg. SRTM DTED level 2) and also reviews various evaluations of the HRS and the ReferenceSD® products made by independent users against ground truth issued from field measurements or high quality/high scale geodata.
