Environment for Spatial Information Sharing

This paper concerns Web-based spatial and local information sharing for digital cities. There are various kinds of spatial information such as geographical maps, illustrated maps, railroad maps and so on around us. Our system provides an environment in which the general users can submit such contents on their favorite map and in which they can view contents submitted from more than two providers on their favorite map. In our system, all spatial information submitted by citizens is linked in special index tables. This paper also shows digital city applications of the presented environments.
