[Termes IGN] temps réelRésumé : (Auteur) Early in 2004, the Geographic Department of the city of Apeldoorn, a large city in the center of the Netherlands, started investigating the options available for creating a realistic digital 3D model of the city. Both still images and real-time applications were required. This project is part of an ongoing movement within the city's organization to continually increase the quality of the geographic data maintened in order to improve communication with the citizens.

[Termes IGN] visualisationRésumé : (Auteur) The experience of compiling historical atlases of Lithuania and of the world in Vilnius University allows asserting that popular methods of systems engineering, such as life cycle modelling, pardigms of thematic map design based on different life cycle models and some general principles of design comprise an effective method to minimize the design costs and improve the quality of the final product.

[Termes IGN] transformation en cosinus discrèteRésumé : (Auteur) The standardization effort of the next ISO standard for compression of the still image, JPEG2000, has recently reached International Standard (IS) status. This wavelet-based standard outperforms the Discrete Cosine Transform (DCT) based JPEG in terms of compression ratio, as well as, quality. In this study, the performance of JPEG2000 is evaluated for aerial image compressions. Different compression ratios are applied to scanned aerial photos at the 1:5 000 scale. Both the image quality measurements and the accuracy of photogrammetric point determination aspects are examined. The evaluation of image quality is based on visual analysis of the objects in the scene and on the computation of numerical indices, including RMSE, entropy, and Peak Signal-to-Noise Ratio (PSNR). The geometric quality of JPEG2000 with different compression ratios is studied for some photogrammetric operations, including interior orientation, relative orientation, absolute orientation, and DSM generation. The objective of this study is to explore the possibility of JPEG2000 for replacing JPEG as a standard in photogrammetric operations.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) In this paper a least squares-based method is proposed for adjusting the boundaries of area objects in a GIS that is designed particularly for solving inconsistencies between the areas of digitized and registered land parcels. The principle of this approach is taking the size of the registered area of a land parcel as its true value and to adjust the geometric position of the boundaries of the digitized parcel. First, a generic area adjustment model is derived by incorporating the following two categories of constraints: (a) attribute constraint: the size of the true area of the parcel, and (b) geometric constraints: such as, straight lines, right angles and certain distances. Second, the methods used to adjust the areas of the parcels for different cases are presented. Third, the implementation of the proposed model is illustrated using several case studies. The results of the application and the corresponding analysis demonstrate that the proposed approach is able to maintain a consistency between the areas of the digitized and registered parcels. This study has solved one of the most critical problems in developing a land/cadastral information system, and this solution has been adopted in the processing of real world cadastral data in Shanghai and other cities in China.

[Termes IGN] utilisateurRésumé : (Auteur) Metadata should help users to assess the quality (fitness for use) of geospatial data, thus reducing the risk of data misuse. However, metadata presents limitations and remain largely unused. There still exists a need to provide information to users about data quality in a more meaningful way. This research aims to dynamically communicate quality information to the users in a rapid and intuitive way in order to reduce user meta- uncertainty related to geospatial data quality, and then reduce the risks of data misuses. Such a solution requires a data model able to support heterogeneous data quality information at different levels of analysis. Using a multidimensional database approach, this paper proposes a conceptual framework named the Quality Information Management Model (QIMM) relying on quality dimensions and measures. This allows a user to easily and rapidly navigate into the quality information using a Spatial On-Line Analytical Processing (SOLAP) client-tied to its GIS application. QIMM potential is illustrated by examples, and then a prototype and ways to communicate data quality to users are explored.
