| 摘 要： | 随着社会的进步和发展,地理信息系统也需要根据用户的需求开发更多的功能。数字视频服务器是一种对音视频数据进行编码处理并完成网络传输的专用设备,可以实现远程监控、语音对讲等功能。将它与GIS结合,可以为GIS提供更加实时的音视频专题信息,GIS也可以对这些信息做出更加科学系统的分析处理,辅助用户做出相应的决策。基于DVS技术的GIS的设计与实现,很好地解决了银行保安、道路监控等实际问题,加快数字城市的建设脚步。

| Abstract: | With rapid development of society, GIS needs to develo Pmore functions according to the need of the customer. The digital video server is a kind of equipment that can encodes and decodes video data and then delivers it on the network. It can also perform remote monitoring. With combination of DVS and GIS, it can provide more real-time video information for GIS, and GIS can also do some more scientific analysis and provide decision-making for customers. For example, bank insurance and road surveillance have been improved with the hel Pof GIS and DVS, which can quicken the construction of digital city. |
