电子平板测图软件EPSW在地籍测绘中的应用

当前计算机技术在测绘领域中的应用正迅速发展，在测图方面，传统的白纸测图因为手工在图纸上按一定比例尺绘制一菜，地物要素导致作业效率低下和原始数量数据精度受损。数字测图是以数字的形式表达地物特征点的全解析机助测图方法，它具有作业效率高，成图规范，原始测量数据精度无损伯的优点。

THE APPLICATION OF ELECTRONIC PLANE SYSTEM SOFTWARE(EPSW) IN CADASTRAL SURVEYING AND MAPPING

In comparison with digital surveying and mapping,plane surveying and mapping has lower efficiency and inferior precision because of manual labour.Digital surveying and mapping is an all-analytic and computer-aided method which represents topographic surface with electronic bookkeeping ,the other is computer.The later leads the direction of digital surveying and quipment:one is with electronic bookkeeping,the other is with computer.The later leads the direction of digital surveying and mapping because of its unique advantages.this paper introduces an electronic plane system software-EPSW and describes how to use it in cadastral surveying and mapping.At last,the writer forecasts its foreground.
