Investigation into the placement and connection of permanent survey marks for cadastral surveys

Abstract

This project investigates the recent trends in the placement of permanent survey marks in Queensland, and reviews suitable methods of connecting cadastral surveys to these marks. Many organisations utilising land information now require more accurate spatial data for their operation. This necessitates the cadastre being accurately connected to the geodetic mapping system which means coordination of land boundaries. To achieve the above aim an overall review of the existing Survey Control Database (SCDB) has been made, both in the field and related to the various directions given to Surveyors. The survey control infrastructure of two areas in South East Queensland has also been analysed. The methods employed in the past for connection of surveys will be analysed to develop the most suitable and cost effective method for today. The initial results show that to provide suitable and efficient connections between the survey control and land boundaries, there must be appropriate regulations and shared responsibility between surveyors and Local Authorities. A major consideration in applying new regulations is the cost and the expected timeframe for results to take effect.
