[Termes IGN] Sousson (rivière)Résumé : (Auteur) This paper proposes a land cover classification methodology in agricultural contexts that provides satisfactory results with a single satellite image per year acquired during the growing period. Our approach incorporates ancillary data such as cropping history (inter-annual crop rotations), context (altitude, soil type) and structure (parcels size and shape) to compensate for the lack of radiometric data resulting from the use of a single image. The originality of the proposed method resides in the three successive steps used: S1: per-pixel classification of a single SPOT XS image with a restricted number of land cover classes (RL) chosen to ensure good accuracy; S2: conversion of RLs into a per-parcel classification system using ancillary parcel boundaries: and S3: parcel allocation using exhaustive land cover classes (EL) and its refinement through the application of decision rules. The method was tested on a 120 km2 area (Sousson river basin, Gers, France) where exhaustive knowledge of land cover for two successive years allowed complete validation of our method. It allocated 87% of the parcels with a 75% accuracy rate according to the exhaustive list (EL). This is a satisfactory result obtained with one SPOT XS image in a small agricultural parcel context.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) A detailed assessment of the plammetric accuracy of highresolution panchromatic Ikonos orthoirnage products for three different test sites is presented. The main objective was to evaluate the potential of Ikonos orthoirnage products for use as digital image basemaps in local government Geographic Information Systems (GIS) systems. For maximum utility and adoption, a planimetric accuracy of 3-5 m and a circular error at 90% probability (CE90) is considered nominal for local government planning and management applications. Lowprecision, lowcost georeferenced Ikonos image products (Geo, 50 m CE90) were orthorectified using third party commercially available software and various custom Digital Elevation Models (DEMs). The planimetric accuracies of the resulting custom Ikonos orthoirnages were found to vary between 2-4 m CE90. In addition, United States Geological Survey (USGS) DEMs were also used to orthorectify georeferenced Ikonos image products. Planimetric accuracies of 2-3 m CE90 were obtained from georeferenced Ikonos using USGS DEMs with RMS vertical accuracies of the order of 2 m. The approach demonstrated here can be used to deliver uptodate, costeffective ortholmages from Ikonos Geo products that yield planimetric accuracies suitable for use as digital image basemaps by local governments.

[Termes IGN] terrainRésumé : (Auteur) The rational function model (RFM) is a sensor model that allows users to perform ortho-rectification and 3D feature extraction from imagery without knowledge of the physical sensor model. It is a fact that the RFM is determined by the vendor using a proprietary physical sensor model. The accuracy of the RFM solutions is dependent on the avaibility and the usage of ground control points (GCPs). In order to obtain a more accurate RFM solution, the user may be asked to supply GCPs to the data vendor. However, control information may not be available at the time of data processing or cannot be supplied due to some reasons (e.g., politics or confidentility). This paper adresses a means to update or improve the existing RFM solutions when additional GCPs are available, without knowing the physical sensor model. From a linear estimation perspective, the above issue can be tackled using a phased estimation theory . In this paper, two methods are proposed : a batch iterative least-squares (BILS) method and an incremental discrete Kalman filtering (IDKF) method. Detailed descriptions of both methods are given. The feasability of these two methods is validated and their performances are evaluated. Some results concerning the updating of Ikonos imagery are also discussed.
