The SurveCE manual states:
"D&R: The user can choose to measure direct and reverse readings for backsight, traverse, resection, topography, or stakeout routines. If the user measures direct and reverse for the backsight readings, all foresight readings that also are recorded direct and reverse will be recorded and computed as angle sets. If the backsight reading is only measured direct, then foresight points that are measured direct and reverse are then combined to produce an average observation record for the vertical circle, which is stored in the .rw5 file as a sideshot (SS) record. For calculation purposes, the routine only averages the distances using both vertical circle readings, and uses the direct horizontal reading for the direction. Both the direct and reverse readings are stored in the .rw5 file as a note record. When disabled, (default setting) only the direct foresight shot will be taken. This option improves accuracy on elevation measurements and mimics a feature found on the SDR data collectors. The Resection D&R will also apply to Remote Benchmark."
1. Does this apply to "Set Collection" only? I thought I recently read that if "Backsight" and "Topography" are checked, this would make "Store Points" act as if you were taking one set of observations, i.e. BD-FD,FR-BR.
2. "Traverse (D&R)" is not mentioned in this section, but if that's checked, does it just do the same thing as "Topography" (i.e. a "sideshot"), but to a point that you will traverse to?
Bottom line:
If one wishes to commence a traverse, doing a single set (BD-FD, FR-BR) using "Set Collection" , how should these check boxes be set?
