The Design and Implementation of Online Video-Distributing System Based on the Technology of Vehicle-Borne Mobile Data Collection System

摘要

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.
