| Outline of Final Research Achievements |
In this research, we have investigated computation mechanisms for variable-scale Web map systems, and we have developed the following systems and clarified their effectiveness by experimental evaluations: 1) a road database system for variable-scale Web maps which makes enriched road network data by perceptual grouping of road segments and by combining them with roadside facilities, 2) a road network generalization system for Web map services, which selectively draws important strokes in a road network to improve visibility without degrading connectivity among strokes and accessibility of facilities on demand, and 3) an efficient path selection system which finds the shortest path among the paths with the minimum number of strokes by using the above enriched road network data.
