Abstract:
WebGIS is the result of combining the technology of Internet with that of Geographic Information Systems (GIS). This paper aims at some problems in the development of GIS, such as the system of development is instable, and presents the method of adopting component technology to accomplish WebGIS middleware which has been successfully applied to the Oil Production Engineering information visible system. It showed in practice that the WebGIS middleware can be easily embedded in the web pages to accomplish GIS application system in a network environment. On the one hand, its application can reduce complexity of system and speed up the pace of development. On the other hand, it is certain to reduce the development costs and improve the maintainability.
