【Abstract】 In the altitudecontrol surveying of mountainous areas,the method of geometric leveling is replaced by the method of GPS altitude control surveying and trigonometric leveling with total station instrument,through which we can get elevation of every test site.Engineering case analysis shows that the method is very accurate and credible,which can entirely meet the requirements of the altitudecontrol surveying in mountainous areas and efficiency is improved greatly.更多还原
