ABSTRACT:Heritage documentation and representation is now a growing concern in the contemporary world, with unprecedentedly rapid technological development that pushes the frontier further every day. This ever growing means benefits both professionals and the general public, and the two can now be connected by this virtual bridge that channels heritage information from one end of the spectrum to the other, thus facilitating a dialogue never considered before. 4D virtual heritage with visualized tempo-spatial information can be easily shared across the continents and the story of heritage is told by a simple move of the thumb. Mobile LBS (Location-Based Service) enhances visitors' on-site experience and is readily available on the popular iOS platform. UGC (User Generated Content) on the internet provides interaction among users and managers, and brings the heritage site and the public into a live conversation. Although the above technological exploration is promising in itself, the question still remains as how it may be best implemented. The Re-yuangmingyuan program for the reconstruction and representation of an imperial garden in Beijing has made several attempts that deserve discussion, and contributes to heritage documentation and conservation in general.

With the fast development of Internet technology, human society is moving into an information age. Digital city, as well as digital earth, has become a new symbol of the progress of society, and at the meanwhile, in order to represent the real world, as we know, GIS has been proved to be the most effective technical platform. Traditional GIS map service generally provides some simple spatial data analysis, such as the enquiry of the location, the shortest path analysis, analysis of the buffer zone, and so on .People online ask for more services with a growing demand nowadays , so these services can no longer meet the people's needs, not only the shortest path between the two places what the computer is giving , they would also like to know more detail about information of this strange street, such as the special features along the street ,so that they can have a direct sense of the street. In order to meet people's needs, and promote the development of GIS map service, the author studies on this area. As we know, there are so many ways to design a WebGIS platform, and this paper chooses a popular one. Based on the technology of asp.net, we can use the ArcIMS to distribute our maps, which is a product of the ESRI, and the activeX to distribute our video, which has been edited. Generally, when you establish a geographic information system, the big problem is the acquisition of data. The vehicle-borne multi-sensor system gets this problem solved. The GPS, one sensor of the multisensor, can get the point's geographic coordinates, so that we can establish a map layer in the Arcview through these coordinates, and distribute the map in the ArcIMS. As the technology of VideoGIS is improving, we can integrate video and spatial information together. As it's not easy to get the map and video synchronous, based on the technology of VideoGIS, this paper gives a solution of this problem in detail. And taking a street of Beijing for example, this paper gives an instance of the video-distributing system.
