Issues of co-ordinate collection technologies for rural property boundary surveys in Queensland

Webb, Robert M. (2006) Issues of co-ordinate collection technologies for rural property boundary surveys in Queensland. Masters by Research thesis, Queensland University of Technology.


The use of co-ordinates as a description of land boundaries and their limitations has been investigated given recent advances in GPS measurement technology and its proliferation in the surveying and mapping industry. While the use of coordinate information is in essence a representation of reality at a given point in time, it is shown that they can be used within a well-defined framework for summary purposes.

The conceptual and operational elements of a measurement-based spatial information system are developed in order to determine if it could aid in the organisation of land boundary information. The fundamental concepts of this information system are that measurements are the primary carriers of metric information. The investigation reveals that measurement-based concepts can serve as the foundation of a multi-purpose spatial information system. Increasing instrument precisions available to surveyors are providing quality measurements with decreasing uncertainties from standard daily operations. Much of this measurement information is in digital form and can provide useful additions of new information as and when they become available to the system. Control measurements are integrated into the system in the same manner as cadastral measurements. The addition of measurements increases the accuracy of the information system over time.

The concept of a local controlled area and surface movement indicators are briefly covered relating to geo-movements of cadastral evidence. Some issues surrounding the historical foundations of geodetic datums are studied as they provides a basis of knowledge of where future spatial information developments may occur given current understandings and technological ability. A review of International and Australian measurement systems is presented. In this context, issues surrounding GPS traceability are explored as a means of demonstrating conformance with suitably recognised quantities of length and time. Discussion is held on the legal acceptance of measurements and reviews rules of evidence questioning the term geographical position used in Australian courts.

An investigative study into rural property boundary surveys for subdivision purposes has been undertaken to provide comparative discussion on issues of changing methods and evolving technology approaches to the measurement challenges using GPS techniques.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
