| 摘 要： | 在已知三、四等三角点或者高精度GPS点的控制下,直接用GPS-RTK测量技术对测区已有的高精度控制点进行图根测量,然后把RTK所测点的坐标数据与原已知坐标数据分别进行两点之间的坐标距离反算,并根据反算的结果进行相对应的对比分析。分析结果表明:GPS-RTK测量的点位精度可以满足大比例尺地形图对图根点测量的精度要求,在小范围面积的地形图测绘中可以采用GPS-RTK这种方法进行图根点测量。

| Abstract: | Abstract: Known to three or four other triangle points or under the control of high-precision GPS points,Direct use of GPS-RTK measurements of high precision control points have been in measuring area,then, according to the RTK coordinates of the measured data points with known coordinates of the original data anti-calculate the distance between two points,and Comparative analysis based on the anti-calculate results.The results show that Point precision of GPS-RTK can meet the large-scale topographic map of the map's accuracy requirements of the root point of measurement,so that GPS-RTK method to map the root point of measurement can be used in the area of small-scale topographic mapping. |
