Abstract
Summary form only given. Geographical data are characterized by their complexity, which has resulted in the appearance of new heterogeneous GIS formats used currently in very varied applications. In this paper, we propose to design and develop a system for the management of geo-referenced data while being based on a set of generic tools treating various GIS formats and to transform them into a standardized single interchange format which could be used in several applications. For realization of this system we used tools such as the GIS GRASS, the translation library GDAL/OGR, the conversion tool FME, the standard XML development environment XMLSpy. Thus, we used languages such as the modeling language UML used to model the geographical data, GML representing the storage and exchange format of geographical data, XSL which is a stylesheet language, and SVG that is a language for the 2D graphic representation of XML data. The system suggested is characterized by a modular architecture allowing fast evolution and a rather easy development.
