RTK技术在山区大比例尺地形图测绘中的应用

传统的模拟法测绘地形图已不能满足生产实践对数字化图的需求，随着测绘仪器和测绘理论及技术的发展，该方法正逐渐被数字化测图所取代，RTK技术以其灵活的地物点坐标采集方式为数字化测图提供了更多选择．作者在分析全站仪数字测图局限性的基础上，介绍了RTK测量技术的工作原理和系统的基本构成，结合测区实际情况分析RTK技术在山地进行地形测图的可行性，完成了RTK外业数据采集和内业成图工作，阐述了RTK采集的数据与成图软件之间通讯时数据格式转换问题，得出了一些有益的结论和建议．

Application of RTK Technique in Large Scale Topographic Surveying and Mapping in Mountainous Area

Traditional analog topographic map plotting can not meet the need of practice for digitalized map. This method is being replaced by method of digital mapping with the development of surveying and mapping instruments, theories and techniques. Using RTK can collect coordinates of ground points flexibly, which provides a practical method for digitalized map. On the basis of analyzing limitation of total sta- tion digital mapping, The paper discusses operating principle and basic constitution of RTK technique. The feasibility of surveying and mapping applying RTK technique considering the actual mountainous area is illustrated, field work and indoor work are done accordingly. Moreover, data formation transformation between RTK data and CASS data is also expatiated.
