In the description of a PLSS corner, exactly what does "referenced" mean when a surveyor writes --
"Referenced, removed and replaced 5/8" iron rod with 2" diameter iron pipe 24" long with 3-1/4" brass cap ..."
Does it simply mean that the bearings and distances from the iron rod to pre-existing bearing trees are re-measured?
What if there are discrepancies between previous surveys and the present one?
