Opis

Since the first symposium in 1984 the International Symposia on Spatial Data Handling (SDH) has become a major resource for recent advances in GIS research. The International Symposium on Spatial Data Handling is regarded as a premier international research forum for GIS. All papers are fully reviewed by an international program committee composed of experts in the field.

The series of International Symposia on Spatial Data Handling started in Zurich, Switzerland, in 1984. Since then it has evolved into a biennial event of high calibre, at which recent trends and developments in geographic information science are discussed. The proceedings of this series have become an important reference for researchers and students in the field of geography, cartography, and geoinformation.
