A new study of weighting method in leveling network adjustment considering the terrain

Aiming at the problem of failing to take the terrain condition affecting the method of height difference weighting into account,it proposes a new leveling network weighting method which takes the terrain condition in the survey area into account.Proved with theoretical analysis and practical data,in the leveling network with both large and small topographic reliefs,test results show that the method has better performance in reflecting the precision of leveling than traditional methods of weight,and covering the deficiency of the traditional one.
