Application Research of GPS Elevation Survey Instead of Grade Leveling
Based on the rapid development of CORS system and refined model of centimeter-level quasi-geoid in recent years,this paper implemented the application of the GPS elevation.The technical indicators with low-grade GPS elevation measurement instead of the third and fourth grade leveling are given by theoretical analysis.The result have been verified by the engineering practice.
