The application of GPS-RTK in the surveying of railway's covering mining resource

In the surveying of covering mineral resources, the location relation of mining (exploration) rights and the railway’s midline are surveyed and put in AutoCAD to reflect the location relation precisely in order to help investigate department definite if those mining rights are covered. GPS-RTK’s accuracy grade is centimetre-sized, it accords completely with the accuracy requirement of surveying of covering mineral resources, at the same time, GPS-RTK’s data is interactive with AutoCAD. The application of GPS-RTK enhanced the surveying precision and efficiency and provided a brand new thinking for later analogous work.
