Be defined as the secondary superposition observation of front-and rear-view, sedimentation value △ h=(h1+h2 ')-(h1+h2), secondary superposition subtractive method it is theoretical according to
According to being trigonometric levelling principle, due to being influenceed and level song by earth curvature and air shading when trigonometric levelling
Influence of the face rate to vertical survey, using horizontal plane replace level surface can produce vertical error, when between 2 points of measurement away from
It is soft generally using Bidirectional observation, but when reclaiming land around sea, it is necessary to be modified to vertical error during from more than 300m
Bidirectional observation can not possibly be carried out in soil base settlement observation, because the result of measurement is not absolute elevation, but relative relief, institute
Vertical error can be considered as a kind of systematic error because the present invention detect be vertically under the same conditions, to sedimentation
The one of mark progress is class observation, and this systematic error can be eliminated in secondary superposition phase loss of weight, i.e. △ h=(h1+h2 ')-(h1+h2)
=h2 '-h2.
