利用遥感影像图进行地名更新

随着测绘新技术的发展,传统的测绘工艺正在发生革命性变革,外业测量工业已经逐步减少。如何与测绘新技术结合,有针对性的采取有关手段核实更新地名变化,扭转目前地名更新周期长的状况,是地名数据库维护工作亟待解决的问题。将影像数据与地名数据叠加分析,可以判断出实体的类型、位置的主化,并分析实体与地名数据的匹配情况,从而达到监测地名变化的目的,为地名数据更新提供新的手段。

The method of utilize remote sensing image graphic to update geographical name data base

With the development of the new technology about surveying and mapping,the traditional technology has been revolutionary changed.Lots of the outside works have been cut down.How to use new technology to rapidly and economically discover geographical name change,so that we can adopt the effective method to check up its change and reverse current situation in which there are no appropriate method to update the geographical name.Superimposing geographical name data on image data to analyze can judge the change of the type and location of graphic entity and analyze the match of entity and geographical name data.Using this method we can monitor the change of geographical name and provide a new method to update it.
