ESRI'98 brings together researchers and practitioners who explored the evolving landscape of geographic information systems at the second French conference on GIS. The proceedings compile a range of papers that examine the diffusion of GIS technologies, share experimental results, and discuss methodological challenges in mapping and data analysis. The volume offers insights into the practical applications of GIS in environmental monitoring, urban planning, and spatial data management, while also addressing theoretical questions about data quality, interoperability, and user experience. By presenting case studies, technical reports, and conceptual essays, the book serves as a valuable resource for scholars, developers, and decision makers interested in the state of GIS research at the close of the twentieth century.
