| 摘 要： | 利用GPS RTK方法测定建筑物墙角点坐标时，由于建筑物的遮挡，很难获得点位的固定解。介绍了一种基于GPS-RTK测定建筑物垂直墙角点坐标的新方法，即垂直外伸法。通过实地采样，借助建立的计算公式，对测定结果进行计算改化及比较，证明该方法测定结果的精度可以满足相应规范的要求，具有一定实用性。

| Abstract: | It is difficult to measure the fixed value of the coordinates of building corner position of building with obstruction using GPSRTK method.This paper introduces a new method of measuring the coordinates of building corner based on GPS-RTK,Vertical Extension.The buiding corner coordinates surveyed by GPS-RTK are compared with that by Total Station.The difference is analysed.The result shows that with Vertical Extensive method,the precision of building corner coordinates can meet the requirement of surveying criterion. |
