Surveying

Types of Surveys

As - Built Survey

A survey undertaken that accurately records the location of services that have been installed as part of a land development.

Cross Lease Survey

When a cross-lease title (see definition) is a created, a survey is required to determine the location of all buildings on the site which are to become lease areas on the new titles, and the position of features which define any exclusive use areas. The survey also determines the location of the existing title boundaries in relationship to the buildings.

E-Survey

E-survey is the electronic transfer of survey data to Land Information NZ for the issue of new titles. This supercedes the traditional method of lodging plans and data in hard form and e-surveys became compulsory on the 1st September 2007.

GPS Survey

A survey undertaken to determine the location of points on the earth utilizing Global Positioning System (GPS) technology, rather than traditional means of recording angles and distances from known points. GPS uses signals from manmade satellites orbiting the Earth to calculate a position on Earth. The accuracy of a GPS survey is determined by the quality of the equipment used, the number of satellites available at any time and the post-processing of the raw data,

Height to Boundary Survey

Local Councils frequently require height to boundary surveys and certificates to determine the location and height of buildings in relation to a adjacent boundary. This is to verify that buildings comply with controls that limit the height of a building relative to the boundary.

Land Transfer Survey

Is a survey that transfers the rights of one title to other titles, by subdivision of land or the creation of units/cross-leases or the creation of easements.

Redefinition Surveys

Are surveys undertaken for the purpose only of reinstating 1 or more parcel boundaries.

Topographic Survey

A survey that measures the elevation of points and position of features on a particular piece of land, and presents them graphically.

Professional Licenses

Licensed Cadastral Surveyor

Licensed cadastral surveyors are authorised under the Cadastral Survey Act 2002 to undertake cadastral surveys (surveys that deal with property boundaries) and prepare survey datasets to enable the creation and transfer of interests in land. They are charged under the act for maintaining the integrity of the cadastre.

Registered Professional Surveyor (RPSurv)

The New Zealand Institute of Surveyors has adopted the term, Registered Professional Surveyor as the title for members of the Institute. Registered Professional Surveyors must achieve a high degree of professional knowledge and agree to abide by the standards set by the Institute on such mattes as quality of workmanship, ethical behaviour, professionalism and ongoing professional development. We insist that all of our Surveyors achieve this standard prior to managing projects, or work closely under the supervision of a Registered Professional Surveyor.

Surveyor's Equipment

Total Station

Is a very accurate instrument used by Surveyors to measure angles and distances. It can be combined with GPS to locate a position on earth sourced from signals from satellites. Measurements can be electronically stored and downloaded into computers.

CAD (Computer Aided Draughting)

All modern Survey offices employ the use of CAD to accurately draught their survey plans. This enable revisions to be quickly made and electronic versions stored on computers. Efficiencies are also obtained when CAD stations are installed with twin screens, to enable two views to be worked on at the same time.
