青藏铁路GIS地图显示风格配置组件的设计及实现

Design and implementation on map display style of configuration module in GIS of Qingzang Railway

地图显示风格一般是以文件方式存放的,而且,不同地理信息系统软件其风格配置文件是不一样的,并且是不透明的,因此,不利于地图显示风格的传播及维护。探讨使用数据库方式,配置地图的显示风格,这样空间数据和地图的显示风格都可以统一的保存到数据库中,以数据库的方式管理和维护,以提高地图显示风格的统一性和可维护性。

The display style of a map was always saved as a file. The style file of different Geography Information System （GIS） software was different and unknown to other, so it was not good for the transmitting and maintenance of map display style. It was tried to put the display style of a map into database, so the spatial data and the display style data could be saved into the same database. The data could be managed and maintained by database, so the display style of a map could be kept same and it could be maintained easily.
