摘　　要：手持GPS接收机接收的WGS84经纬度坐标与我国的平面坐标系基准不统一,需要通过求解参数校正野外测点数据。将算法程序化,面向对象编程实现参数参数求解功能,方便野外地质调查人员随时校正手持机参数,准确获取地质测量数据。The latitude and longitude coordinates in WGS84 gained by the handheld GPS receiver are not unified with the plane coordinate reference in China. On the basis of this, we needed to calculate distinct transform parameters and calibrate the field data. And then, we programmed the algorithm, and realized the parameter calculation function by the object-oriented programming. This study can raise field geological working efficiency and obtain accurate surveying points data.
