Mark type and number

Mark Type and Number will be constructed as follows.

The Mark Type will be one of the following:

CP Mapping Control Point
CR Cadastral Reference Mark
GB Geodetic Bench Mark
MM Miscellaneous Survey Mark
PM Permanent Mark
SS State Survey Mark
TS Trigonometrical Station

The mark type is followed by a number in the range 1 - 99999999. This may be followed by a witness / eccentric number in the range 1 - 99.

The Name is used in conjunction with trig stations and is the Geographical Names Board approved name for the station. If (P) appears at the end of the name, the station is marked with a concrete or steel pillar.

The Alias is a cross-reference to mark identifiers issued by other organisations or the survey mark may have been previously known as a different name or number.
