伴随着我国有线电视技术的日新月异,城市的有线电视技术网络不断整合,经营模式由原来的分散式经营改制成集中式管理,将网络中用户整合一起,而另一方面,传统的数据库管理系统和纸质图纸已经不能满足有线电视网络的发展需求。地理信息系统(GIS)可以通过强大有效的地图功能将复杂的空间数据和属性数据以图形的形式展现出来,从而挖掘数据之间的关联性,打破了传统意义上地图的局限性。本文结合有线电视网络自身特点进行了对地理信息系统(GIS)的功能结构和应用的探讨。 With the rapid change of China’s CATV technology, the city’s cable television technology network continues to integrate. The business model has been transformed from a decentralized management into a centralized management that integrates users in the network. On the other hand, the traditional database management system and Paper drawings can no longer meet the development needs of cable networks. Geographic Information System (GIS) can display complex spatial data and attribute data graphically with powerful and effective mapping function, thus digging the correlation between data and breaking the limitation of traditional map. In this paper, we discuss the functional structure and application of Geographic Information System (GIS) based on its own characteristics.
