Control points

Markers are the preferred method for defining boundaries of loci and baulks. They can then be used as reference points for relays. They are entered by the surveyor in Y01/O/M. Relays to define the boundaries of loci are used when for some reason a marker either does not exsist or the surveyor is unavailable. They can be found in J03/D/R
