Abstract: Aiming at the problems such as limited interactivity and lack of dynamic and multi－dimensional display ability of commercial studio software when processing the studio related to geographic information, a multi－source dynamic demonstration system based on WebGIS is designed. It discusses the overall framework, database design and technical system of the system, and analyzes the key technologies such as demonstration page structure design, demonstration arrangement design, data automatic mapping and map service construction. Taking the driving route demonstration from Chengdu to Lhasa as an example, it also discusses the editing of association layer, editing of studio project and demonstration show.
