Uses entire station meter Shi Ceda the cross section the method mainly to have the coordinate and the opposite side survey law two kinds. Erects the control point the entire station meter the coordinate survey law, the merit is may unifies the topographic survey and the big cross section survey also carries on, but increased the quantity to take the instrumental height the error, the survey elevation's precision compared does not erect must be slightly low in the control point coordinate and the opposite side survey law. Does not measure takes the instrumental height the coordinate and the opposite side survey method measuring accuracy is the same, may meet four and so on leveling requirements at least. The recommendation uses entire station meter opposite side survey law Shi Ceda the cross section. The opposite side survey law is more advanced than the coordinate survey law, the measuring accuracy is higher, sets up a station the operation only to need to level off the instrument strictly, the survey record data quantity are few, moreover does not need to transform the data through the computer, makes the simple algebra and the operation to various measuring points' elevation difference, then forms the big cross section survey achievement. Should pay attention to the following several points for the guarantee elevation measuring accuracy: Observes the personnel first to want the fine sight to the pole's prism center; Maintains as far as possible to the pole highly is lowest and fixed invariable, holds the pole person to pour on rhabdomere's round standard to soak closely comes, guaranteed that is at the vertical condition to the pole; Between two measuring point's distances cannot be too long, farthest does not surpass 500 m; Should establish as far as possible the instrument in two measuring point segment center point or approaches the segment. Looking from the practical application, the entire station meter is more advanced than the traditional level, the survey and the computation work load are the reductions greatly, and are been few topographical condition's limit, the work nimble, direct-viewing, the operation is simple, the survey speed is quick, the precision is high, may raise the working efficiency greatly and reduce the labor intensity, can replace the level to carry on the big cross section survey.
