| Abstract: | Geo data is very important to geo study. This paper overviews several geo data sharing systems in Internet and discusses the role of geo data sharing over Internet. The paper also overviews technique problems in Internet Geo data sharing which mainly includes meta database based and WebGIS based. Finally the paper draws the conclusion that geo metadata visual query and geo data fusion are two important issues in geo data sharing in Internet. An appendix of Internet HomePage addresses of several Internet Geo data sharing systems is provided. |
