IGIS '94: Geographic Information Systems: International Workshop on Advanced Research in Geographic Information Systems Monte Verità , Ascona, Switzerland February 28 – March 4, 1994 Proceedings

"This volume constitutes the proceedings of the International Workshop on Advanced Research in Geographic Information Systems, IGIS '94, held in Ascona, Switzerland in February/March 1994. The 28 carefully refereed and revised papers address all current aspects of GIS research and their advanced applications to spatial and environmental data engineering. Among the topics covered are GIS theory, spatial databases, spatial data structures, environmental modelling and control, data modelling, object-orientation, pattern recognition, and optimization. In addition, software and non-commercial as well as commercial GIS are analysed."--PUBLISHER'S WEBSITE Content: Front Matter....Pages - Environments for land application development: issues and design guidelines....Pages 1-14 Modelling a hierarchy of space applied to large road networks....Pages 15-24 Approximations for a multi-step processing of spatial joins....Pages 25-34 First experiences with GEOSTORE, an information system for geologically defined geometries....Pages 35-44 The DOMUS project — Building an OODB GIS for environmental control....Pages 45-54 Virtual geographic information system (VGIS)....Pages 55-58 Multiple representation modelling and querying....Pages 59-69 Surface modelling with guaranteed consistency — An object-based approach....Pages 70-87 Hierarchical hypersurface modeling....Pages 88-97 Spatial reallocation of global gridded climate datasets....Pages 98-108 Development of specialized geographical information systems for the analysis of large scale radioecological accidents....Pages 109-112 On quality paths on polyhedral terrains....Pages 113-122 Algorithms for automated extraction of man-made objects from raster image data in a GIS....Pages 123-132 A prototype spatial data environment for urban design....Pages 133-142 Knowledge-based systems coupled with geographic information systems....Pages 143-154 Sustained spatial data management in real-world projects — A research focus....Pages 155-167 A storage manager for the development of spatial data structures....Pages 168-177 CARTECH: a prototype of geographical information system....Pages 178-191 COSIMA A network based architecture for GIS....Pages 192-201 The XYZ GeoServer for geometric computation....Pages 202-213 Patchwork — A query-driven locally adaptive data space partitioning....Pages 214-224 Recognition of urban roads on large-scale maps: the prototypical cases....Pages 225-236 Intelligent decision support based on GIS: The EcoRisk Project....Pages 237-246 Optimizing spatial data structures for static data....Pages 247-258 A hybrid pointerless representation of quadtrees for efficient processing of window queries....Pages 259-269 Optimization issues in R-tree construction....Pages 270-273 VisTool: A visualization tool for spatial access structures....Pages 274-287 Relation-based information processing with symbolic spatial indexes....Pages 288-291 Back Matter....Pages - Constitutes the proceedings of the International Workshop on Advanced Research in Geographic Information Systems, IGIS '94, that was held in Ascona, Switzerland in February/March 1994.
