Visual Query Processing for GIS with Web Contents
Ryong Lee, Hiroki Takakura, Yahiko Kambayashi · 2002
In many geographic objects such as a travel planning, the use of web information is significantly increasing. For an efficient support of such work, it is very important to combine web information with map semantics. Current web systems usually do not support map semantics. Conversely, conventional Geographic Information Systems (GIS) do not utilize the web resources. The purpose of the research is as follows: (1) to get semantics from the web contents to realize advanced GIS functions on geographic web searches, and (2) to develop a user interface which can utilize web contents and map semantics in an effective integrating way. For such a purpose, we construct two map semantics about geographic characteristics and relationships available on the web. Utilizing semantics, we have developed a prototype system, KyotoSEARCH; its main function is to support users’ information navigations among the web, the map and web-based geographic knowledge, in an integrated way.
