| 摘 要： | 从传统的重力地形改正方法入手,用VC~( )语言编制了重力地形改正可视化程序。它能用于重力近中区地形改正,并能满足重力地改的精度要求,使得多年来重力近中区地形改正繁重的手工数图工作能够用计算机完成,且计算精度和速度得到明显提高。通过人机对话的形式(操作界面),可直接计算出近、中区的地形改正值。

| Abstract: | Starting with the traditional terrain correction technique,the author completed Windows programming by using Visual C~( ) language,which can be used in gravity near and medium region terrain correction,and can meet the precision requirement,thus making it possible for computer to perform the gravity near and intermediate area terrain correction which had to be completed by manual calculation in the past and hence evidently raising the calculation precision.This procedure is very convenient and quick to calculate the value of terrain correction by using a dialogue between man and compute. |
