| Abstract: | The rapid development of Internet technology makes it possible to integrate GIS with the Internet, forming Internet GIS. Internet
GIS is based on a distributed client/server architecture and TCP/IP & IIOP. When constructing and designing Internet GIS,
we face the problem of how to express information units of Internet GIS. In order to solve this problem, this paper presents
a distributed hypermap model for Internet GIS. This model provides a solution to organize and manage Internet GIS information
units. It also illustrates relations between two information units and in an internal information unit both on clients and
servers. On the basis of this model, the paper contributes to the expressions of hypermap relations and hypermap operations.
The usage of this model is shown in the implementation of a prototype system. |
