"Headway in Spatial Data Handling" is a specialized book that documents the results of the 13th International Symposium on Spatial Data Handling. This symposium, which has been held every two years since 1984, serves as a significant forum for research and discussion on topics such as spatial and temporal modeling, data integration, visual representation, and semantics. The book provides a comprehensive overview of the latest developments and challenges in the field of geographic information sciences. It is aimed at professionals, researchers, and students engaged in the analysis and management of spatial data. The topics addressed are crucial for sustainable development, climate change, and economic development, as they help facilitate human activities and understand their impacts on space. The editors, Anne Ruas and Christopher Gold, have compiled a collection of contributions that reflect the diversity of approaches and perspectives in this dynamic research field.
