Addressing Unclear Right of Way Issues through Infrastructure Management System in Nonthaburi Provincial Administrative Organization.

Abstract

Nonthaburi Provincial Administrative Organization (PAO) manages extensive infrastructure assets, including bridges, buildings, land parcels, footpaths, and roads. Historically, right-of-way management has been problematic due to unclear boundaries, which are crucial for maintenance planning, design improvements, and construction within these areas. Utility construction permits for infrastructure like drainage, water supply, and electricity often face right-of-way overlaps, and land surveying is costly and resource-intensive. This research explored using land parcel data from a Web Map Service (WMS) with QGIS to address unclear right-of-way issues by comparing it with actual surveys of 30 parcels. The objectives were to (1) assess data accuracy and (2) study the feasibility of using right-of-way width data to reduce field surveys. The findings indicated that right-of-way width analysis had an approximate 10% error rate but significantly reduced the need for fieldwork, resulting in savings in manpower, fuel, and overall expenses. While not legally binding, this data can guide the PAO's infrastructure management system for right-of-way consideration, planning, and management, as well as support utility integration and collaboration with external agencies for sustainable local infrastructure development in the future.
