This research thus compared two methods for the orthorectification of the complex SAR data: The polarimetric processing is performed before (image-space method) or after (ground-space method) the geometric processing. Radarsat-2 fine-quad data acquired with different look angles over a hilly relief study site were orthorectified using accurate light detection and ranging digital surface model. Quantitative evaluations between the two methods as a function of different geometric and radiometric parameters were thus performed to evaluate the impact during orthorectification. The results demonstrated that the look angles and the terrain slopes can potentially corrupt the polarimetric complex SAR data during its orthorectification with the ground-space method. In addition, general advice is provided to reduce these impacts to an acceptable level for the users and their polarimetric applications.

A "new hybrid" modelling for geometric processing of Radarsat-2 data without user's GCP / Thierry Toutin in Photogrammetric Engineering & Remote Sensing, PERS, vol 77 n° 6 (June 2011)  

Public [article]  inPhotogrammetric Engineering & Remote Sensing, PERS > vol 77 n° 6 (June 2011) . - pp 601 - 608 Titre : A "new hybrid" modelling for geometric processing of Radarsat-2 data without user's GCP Type de document : Article/Communication Auteurs : Thierry Toutin , Auteur ; K. Omari, Auteur Année de publication : 2011 Article en page(s) : pp 601 - 608 Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Traitement d'image radar et applications [Termes IGN] GPS-INS [Termes IGN] image Radarsat [Termes IGN] modèle géométrique de prise de vue [Termes IGN] modèle par fonctions rationnelles [Termes IGN] traitement d'image radar Résumé : (Auteur) The objective of the research study is to use the synergy of 3D empirical (Rational Function Model (rfm) and physical (Toutin's) geometric models to develop a "new hybrid" model for the geometric processing of Radarsat-2 data without collecting ground control point (GCP). After independently evaluating the processing and the accuracy of each model using accurate differential GPS points, RFM was thus used to generate few "virtual" rfm points at the highest elevation of the study site. In addition to information of the metadata, these "virtual" points were input as GCPs in Toutin's model. This new hybrid model consistently achieved pixel accuracy, with better results for steep looking angles than the two other models. Its main advantage was, in addition, to be used without collecting GCP, increasing the applicability of Radarsat-2 data in remote areas.

Radarsat-2 data: automated high accuracy geometric correction and mosaicking without ground control points / Penggen Cheng in Geoinformatics, vol 13 n° 5 (01/07/2010)

Public [article]  inGeoinformatics > vol 13 n° 5 (01/07/2010) . - pp 22 - 27 Titre : Radarsat-2 data: automated high accuracy geometric correction and mosaicking without ground control points Type de document : Article/Communication Auteurs : Penggen Cheng, Auteur ; Thierry Toutin , Auteur Année de publication : 2010 Article en page(s) : pp 22 - 27 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Traitement d'image radar et applications [Termes IGN] géoréférencement direct [Termes IGN] image radar [Termes IGN] image Radarsat [Termes IGN] mosaïquage d'images [Termes IGN] orthoimage [Termes IGN] orthorectification automatique [Termes IGN] point d'appui [Termes IGN] Radarsat Résumé : (Auteur) Imagine a fully automated system used to produce accurate high resolution radar ortho-image and -mosaics all over the world with excellent reliability! Emergency management teams could then have access to highly-accurate radar data as soon as it becomes available for their time-sensitive needs. This was a difficult task, mainly due to the arduous process of collecting ground control points (GCPs). It is now possible with the successful operation of the radarsat-2 satellite and a new 3D hybrid satellite model that process this data without user-collected GCPs.

ASTER DEMs for geomatic and geoscientific applications: a review / Thierry Toutin in International Journal of Remote Sensing IJRS, vol 29 n° 7 (April 2008)  

Public [article]  inInternational Journal of Remote Sensing IJRS > vol 29 n° 7 (April 2008) . - pp 1855 - 1875 Titre : ASTER DEMs for geomatic and geoscientific applications: a review Type de document : Article/Communication Auteurs : Thierry Toutin , Auteur Année de publication : 2008 Article en page(s) : pp 1855 - 1875 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications photogrammétriques [Termes IGN] données localisées 3D [Termes IGN] extraction de données [Termes IGN] image optique [Termes IGN] image Terra-ASTER [Termes IGN] modèle numérique de terrain [Termes IGN] modèle stéréoscopique [Termes IGN] positionnement absolu Résumé : (Auteur) Most geoscientific applications using georeferenced cartographic/geospatial data require good knowledge and visualization of the topography of the Earth's surface. For example, mapping of geomorphological features is hardly feasible from a single image; three-dimensional (3D) information has to be generated or added for a better interpretation of the two-dimensional data. Since the early emergence of earth observation satellites, researchers have investigated different methods of extracting 3D information using satellite data. Since the early experiments with the Earth Terrain Camera flown onboard SkyLab in 1973 to 1974, various analogue or digital sensors in the visible or microwave spectrum have been flown to provide researchers and geoscientists with spatial data for extracting and interpreting 3D information of the Earth's surface. Stereo viewing using digital scanner images, such as with the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) along-track sensors, was, and still is, the most common method used by the mapping, geomatic, and geoscientific communities for generating digital elevation models (DEMs). This paper will review the basic characteristics of stereoscopy and its application to the ASTER system for DEM generation. It will thus address the methods, algorithms and commercial software to extract absolute or relative elevation and assess their performance using the results from various research and commercial organizations. It will finally discuss the use of stereo ASTER DEMs for different geomatic and geoscientific applications.
