Many current historical GIS platforms are so technical that their public applications are limited.To address this problem,we examine the public's needs and interests,and subsequently,select the Three Kingdoms period,a typical era of war,for our project. We select and arrange Chinese historical classics and maps to complete the design and implemen-tation of the Three Kingdoms Historical WebGIS. The system uses B/S architecture and consists of four main functional modules:situation analysis,war simulation,character tracking,and remains retrieval. The Three Kingdoms Historical WebGIS system represents historical geographical information by means of information retrieval,map animations, sequence maps,timeline maps,3D scene simulation,and other forms of presentation. The system also offers substantial multi-feature spatio-temporal information about characters,events,times,and places. The test results show that the inter-face is user-friendly,and that its functions are easiere for the public to use. The system implements a dynamic spatio-temporal expression of historical events and a situational expression of historical scenes.
