Evaluating the Impact of the Fourmil Standard Meridian on Cadastral Survey Accuracy in Modern Surveying Techniques: A Case Study in PNG UoT, Lae Morobe, PNG

Abstract

The establishment of the Fourmil Standard Meridian in Papua New Guinea has had a significant impact on the accuracy of cadastral surveys in the region. This study examines the effects of this meridian on modern surveying techniques, with a focus on its influence on the quality and reliability of spatial cadastral data. Through a case study approach, the research investigates the challenges and opportunities presented by the Fourmil Standard Meridian, analysing its influence on boundary delineation, parcel identification, and spatial data integration. The findings provide insights into the importance of understanding the historical context and spatial infrastructure in improving the overall cadastral system and supporting land tenure security in developing countries. This study evaluates the impact of the Fourmil Standard Meridian on the accuracy of cadastral surveys in modern surveying techniques, with a specific focus on Papua New Guinea (PNG). The Fourmil Standard Meridian serves as a critical reference for angular measurements in surveying, influencing the precision of land boundary definitions. The research highlights the integration of advanced surveying technologies, such as Real-Time Kinematic (RTK) Global Positioning System (GPS) and Unmanned Aerial Vehicles (UAVs), which have significantly enhanced the accuracy and efficiency of cadastral surveys. In PNG, where land tenure issues are often complex and contentious, the application of these modern techniques is essential for effective land administration and conflict resolution. The study further discusses the Fit-for-Purpose Land Administration (FFPLA) approach, which emphasizes adaptable and cost-effective land management systems. By leveraging contemporary surveying methods within this framework, stakeholders can improve the maintenance and updating of cadastral data, thereby securing land rights and promoting sustainable development. The findings underscore the importance of the Fourmil Standard Meridian in conjunction with modern surveying technologies in addressing the challenges of land administration in PNG.
