Abstract

This study was motivated by the large number of Cluster 4 (K4) land parcels that have been certified but remain unmapped or possess low-quality spatial data, thereby hindering the realization of complete cadastral maps within the Complete Systematic Land Registration (PTSL) program. The study also considers the importance of utilizing photogrammetric technology as an alternative approach to accelerate the improvement of land data quality. This research aimed to analyze the accuracy level of land parcels generated through photogrammetric mapping compared with terrestrial measurements and to evaluate the conformity of parcel boundaries within the framework of the Cadastral Triangular Model (CTM), which consists of physical boundaries, digital spatial boundaries, and documentary boundaries. Accuracy testing was conducted based on three parameters: position, shape, and area of land parcels. This research employed a mixed methods approach using an explanatory sequential strategy. The first stage consisted of comparative quantitative analysis to assess accuracy using three main parameters: Polygon Near Distance for positional accuracy, Polygon Area for area accuracy, and Polygon Circularity Ratio for shape accuracy. The second stage applied a descriptive qualitative approach through in-depth interviews with land officers to examine their experiences in terms of result accuracy, time efficiency, and ease of technical implementation in the field. The results showed that the positional accuracy of land parcels derived from photogrammetric methods compared with terrestrial measurements was relatively low, with an acceptance rate of only 30%. Meanwhile, shape accuracy indicated no significant difference and was considered suitable based on the circularity ratio. For area accuracy, 53% of the parcels were accepted, although statistical tests indicated significant differences. Analysis using the Cadastral Triangular Model (CTM) revealed inconsistencies in the positional aspect but stable results in terms of shape and area, with area conformity among physical, documentary, and digital spatial boundaries ranging from 78% to 96% without statistically significant differences. In addition, land officers demonstrated positive perceptions regarding the use of drone imagery maps, as they were considered sufficiently accurate in open areas, improved the efficiency of K4 data quality enhancement, and facilitated land parcel identification and digitization processes, although field validation remained necessary.
