A structure of application system is introduced for quickly building an enterprise level webGIS by analysing the structure and data type of current commercial webGIS.A pair of middleware to control and transmit data is designed and implemented for reducing the network bandwidth consumption in webGIS application.The components could compressand decompress the datawithtransparency method between browser and webGIS server by controlling data transmission mode.It could be integrated into user's application system and work with primary WebGIS without any modifications,so that the system gets extended and it has a variety of applications.The results show that it can meet most of requirements of enterprise level applications.
