谈谈野外采集数据大比例尺数字测图的平面精度

The Precision of Large-scale Digital Surveying and Mapping by Field Collect Data

由于测绘科技的发展，数字制图系统已广泛地应用于城市大比例尺测图工作，并实现内外业一体化，为建立地理信息系统提供最原始的基础数据。但是究竟其测量成果的精度如何？

Digital surveying and mapping system is applie d widely to urban large-scale surveying and mapping work because of the development of science and technique of surveying and mapping.Integration of indoor and field work supplies GIS with the original data. How is the plane precision of surveying achievement yet? The thesis discusses the precision of the achievement by commonly useful surveying method.
