Abstract | This paper reports findings of an empirical study into the accuracy and precision of 'measuring' (more correctly calculating or deriving) lines on a cadastral survey from RTK GNSS observations at each end of the line. Unlike earlier publications on this topic that relied on zero-baselines for data analysis, this research uses a range of physical baselines selected to represent typical conditions that may be encountered on a cadastral survey. The research also privileges observations at each end of the line that are taken in quick succession rather than the more generalizable notion of observations taken at any particular time. Results indicate that, provided appropriate corrections are applied, RTK GNSS can provide accurate distances and the accuracy is not expected to degenerate substantially as a function of the length of the line being measured (derived). Preliminary analysis indicates that if observations are taken in quick succession, the distance above which distances may adequately be derived by RTK, and below which distances ought to be measured with a conventional total station could be shortened, but a cautious approach to this is recommended with great emphasises on the need to build redundancy and independent checks into surveys. Further focussed research will be undertaken to test this hypothesis and results will be published in the near future. |
