More Than One Surveyor

Careful consideration must be exerted in situations where more than one surveyor’s work may influence the restoration of a corner. Some pertinent questions which may help in determining which method of restoration to use are:

  1. How well do the surveyors agree in bearings and distances?
  2. How precise are each surveyors’ closures?
  3. Was the terrain comparable for each surveyor?
  4. How long a time period between the surveys?
  5. How recent was the last surve

Caution: More recent surveys accurate, but not always!

Additional retracement of each surveyor’s work in the same township may help to substantiate a preference (confidence) for using his work or giving his work more weight than another surveyor’s work.

Conventional methods of corner restoration may give way to the preponderence of evidence.

Problem: The corner of sections 10, 11, 14 and 15 is lost, as well as the 1/4 corner between sections 10 and 15. How should they be restored?

Surveyor “A” Called distance as 40’s and 80’s. Did not close any section
In this example, the preponderance of evidence indicates that the reestablishment of the section corner by the method of two-point control using surveyor “B’s” work is better than blindly using the conventional method of double proportional.
