东莞市高山区域数字化地形图测量方法研究

Research on Measurement Methods of Digital Topographic Maps in High Mountain Areas of Dongguan City

利用地理信息、遥感以及航空摄影等新技术并结合外业修补测工作,以东莞市已有控制点、航飞影像图等基础数据为基础,探讨东莞市高山区域数字化地形图测量技术方法,为完善东莞市大比例尺基础测绘数据资料和助力自然资源“一张图”建设作技术支撑[1]。

This paper uses new technologies such as geographic information,remote sensing and aerial photography,combined with field correcting and supplementary survey work and based on the existing control points,aerial images and other basic data in Dongguan city,to discuss the measurement technological methods of digital topographic maps in the high mountain areas of Dongguan city.The method is to provide technical support for improving the large-scale basic surveying and mapping data in Dongguan city and assisting the construction of"One Map"of natural resources.
