GPS技术以其精度高、速度快、布网灵活的特点已被广泛应用于测量的各个环节。同时随着RTK技术的日日臻成熟，越来越多的测绘生产单位运用全站仪配合RTK获取大比例尺带状地形图要素信息来满足带状工程用图需求。%GPS technology has been widely used to measure all aspects for its high accuracy, fast speed and flexible distribution network. At the same time, as the RTK technology has matured day by day, more and more surveying and mapping production units begin to use total station to get the strip topographic maps with large scale with RTK to meet the band engineering drawing needs.
