Study on Built-Up Land Development in the Mebidangro Metropolitan Area

Abstract

A spatial planning essential as a regulatory reference in developing an area to ensure its growth remains regulated and monitored. Unplanned built-up land expansion that deviates from the spatial plan could increase urban growth, often called urban sprawl. This study aims to analyze the development of built-up land over three periods of the establishment the Mebidangro Spatial Plan, in alignment with the National Strategic Spatial Plan of Metropolitan Mebidangro. The previous researches focused on one of two things, namely image analysis or policy review, while this research combines both. Our study addresses the gap of prior studies that examined spatial development without linking it to the policy. The research divides the timeframes into three periods: before the plan's enactment period, the early enactment period, and the mid-enactment period. This study uses spatio-temporal data from Landsat imagery, processes it through Google Earth Engine, and verifies the image data in ArcGIS Pro. The results indicate a significant increase in built-up land from the early enactment to the mid-enactment period, forming a centroid pattern. In terms of spatial planning, the expansion of built-up areas which increased 41.55% remains consistent with the designated spatial structure of the NSA. Nevertheless, continuous monitoring and periodic review are necessary to anticipate potential urban sprawl.
