Overview of G-XML - a standard XML based protocol for spatial data exchange

摘要

The G-XML project was a joint project organized by universities, governments and companies in Japan from July 1999 through March 2000 for establishing a standard XML based protocol for spatial data exchange, that is, the G-XML protocol, between any GIS (Geographic Information Systems) including ubiquitous GIS. Some prototype systems based on the G-XML protocol have been already developed as software components, and their source codes will become open in May 2000. Some companies had already used the alpha version of open source codes and developed some experimental applications based on the G-XML protocol. This paper introduces the capabilities of the G-XML protocol and its real applications.
