| 摘 要： | 石油物探测量物理点平面坐标和高程采用1954年北京坐标系和1956年黄海高程系统,GPS测量以作业速度快、精度高、全天候的优点成为物探测量的主要方法,采用GPS观测所得到的高程为大地高,要得到正常高,需要有高程异常数据。利用CQG2000高程异常模型软件或高程异常等值线图求取的高程异常值准确可靠。我国范围在WGS-84...

| Abstract: | The Beijing Coordinate System(1954) and the Huanghai Height System(1956) are to be used when calculating the final coordinate and height for petroleum geophysical exploration surveying geophysical points,GPS to work for measuring speed,precision and an all-weather advantage of the primary method for geophysical exploration surveying,The use of GPS observation of height is ellipsoid height,to establish a geoid height needs height anomaly value.CQG2000 height anomaly model software or height anomaly map get h... |
