conventional surveying techniques and instruments but modern techniques rely
heavily on global positioning because of its high accuracy over long distances.
Cadastral surveying is the determination of the legal boundaries of a parcel of
land. It is sometimes called Boundary Surveying or even simply Land Surveying.
It encompasses original and retracement surveys of both private and public lands.
It is the branch of surveying which will be discussed in this topic.
Cadastral surveying is the determination of the legal boundaries of a parcel
of land.
Boundary surveys often include a plan, prepared by the surveyor, showing
the results of the survey. A properly prepared plan will show the bounda-
ries of the parcel, and the evidence used to locate those boundaries. The plan
will also show the type and location of monuments that were set to fix the
boundaries on the ground, and the location of buildings, natural features and
improvements on or adjacent to the property. The plan should also show any
encroachments and evidence of occupation. The plan is essentially a record of
the survey.
Boundary surveys have the potential to affect the legal rights of the property
owner and the abutters. Because of this, land surveyors have an obligation not only
to their client, but to the public to insure that their survey work is performed with
adequate precision and accuracy and that the legal rules governing boundary loca-
tion have been carefully considered and properly applied.
