Until recently, ArcView GIS technology was used by many organizations to analyze geographic information systems data for a variety of requests. The military tip system is one of these applications in Taiwan. And now we can use the technology of Internet Map Server with Microsoft Internet Information Server to share this GIS application over the Internet. It allows more than one user to access dynamic maps at the same time and to publish any map that can be made in ArcView GIS via the Web. Moreover, administrators can log in remotely to manage and query their map server system.
