Vol. 11 No. 1 (2025): Melanesian Journal of Geomatics and Property Studies (MJGPS) Volume 11 - 2025

This issue of the journal brings together five rigorously peer-reviewed papers that advance scholarship at the intersection of geomatics, land administration, spatial technologies, and landed property systems, with a strong empirical focus on Papua New Guinea (PNG). Collectively, the contributions illuminate both enduring institutional challenges and emerging technological opportunities shaping land governance and spatial data infrastructures in developing contexts. The first paper critically examines the operation of value-based land taxation in Lae City, highlighting institutional, fiscal, and cadastral weaknesses within PNG’s unimproved value rating system. It underscores the central importance of accurate valuation rolls, updated fiscal cadastres, and effective enforcement for sustainable local government revenue and urban management.
The second paper demonstrates the application of UAVs and remote sensing for rural planning in the Nomad District, situating geomatics innovation within challenges of accessibility, land-use planning, and natural resource management, and reinforcing its relevance for evidence-based rural development.
Revisiting foundational cadastral principles, the third paper evaluates the contemporary relevance of the Fourmil Standard Meridian, illustrating how legacy survey frameworks can be harmonised with modern technologies such as RTK GNSS and UAVs to enhance cadastral accuracy and tenure security.
The fourth paper extends the discussion into digital spatial governance by assessing blockchain architectures for large-scale geospatial data distribution, offering insights into scalability, security, and energy-efficiency considerations relevant to national spatial data infrastructure custodians.
The final paper examines the sustainability of economic benefits delivered to mining-affected communities in Western Province, revealing limitations in compensation-driven development models and emphasising the need for coordinated stakeholder engagement and complementary investment strategies.
Together, these papers reaffirm the multidisciplinary nature of geomatics and landed property scholarship, where technical, institutional, socio-economic, and technological dimensions are deeply interconnected. The Editorial Board commends the authors for their contributions and anticipates that this issue will inform policy, professional practice, and future research in PNG and comparable settings.
