Use Geospatial Web Service to Access Geospatial Data Base on Web2.0

Due to rapid development of the internet, it changes the life style of the human. The internet expert had reported that we are now in Web2.0 era. This research tries to explore how web GIS can fullfil the spirit of the Web2.0 and its possible applications.
The first step of the research is to review the related techniques and applications of Geospatial web services and Web2.0. Then, a system with open GIS data structure was proposed and a web system was also established according to the spirit of Web2.0 - ¡§user participation¡¨. Web Map Services (WMS) and Web Feature Services (WFS) defined by Open Geospatial Consortium(OGC) were used in Geospatial web services system to search and view Geospatial data on the internet. Users can integrate spatial data from various sources on the internet and their own geospatial data and save as Web Map Context (WMC) file format. Then, WMC can be exchanged by other OGC Geospatial web services. In addition, the system supports file format transformation from WMC to KML, which is compatible with Google Earth. So users can use Google Earth to view the spatial layer information more easily.
This study also developed a platform to demonstrate geospatial information in the blog, so users can share their Geospatial data in open GIS format with other bloggers. The system also use Google Map API and folksonomy in the data sharing process in order to speed up the web flow and to communicate their comments more easily.
