【Abstract】 A WebGIS model based on component is put forward after analysis of the main techniques adopted in WebGIS. The designing idea and realizing techniques related to different layers of the model are discussed in detail. The model which takes CORBA/Java as its basis of techniques and combines with OpenGIS specification, solves the problems of sharing spatial geographical information and interactive operation.更多还原
