| Abstract: | According to the primest elements consisted of three dimensional networks,the formulae of mean square error about the planimetric, vertical and space point position of all kinds of three dimensional networks were derived.The relative error curves were graphed by the analogue calculation. In the light of the graphs, the inner error influence laws of all kinds of three dimensional networks were analyzed. Moreover, every actual application conditions are given. The conclusions obtained in this paper can be a reference for surveying and mapping production units. |
