There are six cases to consider: ======== ==== ============= ======================================== Case Flag Solutions Symptoms ======== ==== ============= ======================================== CASE 1A: 0 No correction Recorded and actual Line lengths same Reading densities vary slightly (passed the tolerance test) -------- ---- ------------- ---------------------------------------- CASE 1B -1 No correction Line lengths same Reading densities vary and cannot pass the tolerance test -------- ---- ------------- ---------------------------------------- CASE 2A 1 Corrected by Recorded line length too short extension Possible high readings in segment(s) Corrected (by extending) and actual lengths become the same -------- ---- ------------- ---------------------------------------- CASE 2B 2 Corrected by Recorded line length too short interpolation Possible high readings in segment(s) Corrected (by extending) and actual lengths are not same. Interpolation is then applied -------- ---- ------------- ---------------------------------------- CASE 3A 1 Corrected by Recorded line length too long shifting or Possible low readings in segment(s) (shrank) Corrected (by shifting) and actual lengths are same -------- ---- ------------- ---------------------------------------- CASE 3B 2 Corrected by Recorded line length too long interpolation Possible low readings in segment(s) Corrected (by shifting) and actual lengths are not same. Interpolation is then applied ======== ==== ============= ======================================== TERMINOLOGY: Segments A segment refers to the distance and its contents between two adjacent fiducial markers Normal Density The density (number of readings) shared by the segments in a survey line. The number of segments with the density is greater than the number of segments having a different density in a line. Tolerance and Bound: Tolerance is defined as a percentage, say 50% (=0.5). Based on the tolerance, a lower bound and upper bound can be defined: :: Lower bound = (Normal Density) - (Normal Density)*Tolerance Upper bound = (Normal Density) - (Normal Density)*Tolerance Segments will pass the tolerance test if the number of readings falls within the Lower and Upper Bounds.
