Land Boundary Delineation to Supporting of Program Systematic Complete Land Registration (PTSL) Using Multicopter-RTF Data (Case study: Wotan Village, Panceng Sub District, Gresik district)

According to statutory regulation issued by Ministry of Land and Spatial Planning/Head of National Land Agency (BPN) number 35/2016, Comprehensive Systematic land registration is a sequential activity of which continuously and systematically carried out by the government ranging from collecting, processing, recording and presenting, as well as maintaining the physical and juridical data in the form of map and list of land-plots and flats, including the transfer of legal title for land plots and flats with their inherent rights. Delineation is one method to identify land plots by utilizing map image or high resolution photo and defining the boundaries by drawing lines to determine the valid and recognizable boundaries. A guideline to delineate the unregistered land plots may be determined from this two methods' accuracy result, using general boundary applied to aerial photo taken by multicopter RTF. Data taken from a height of 70 meter on an area obtained a number of 156 photos with 5 GCP resulting in an photo map with GSD 2.14 cm. The 11 samples parcels are selected in the sites of ± 7 ha. There are 11 samples of land parcels are tested. The area difference test for every parcel using a average standard deviation of 17,043 indicates that there are three land parcels which have significant area difference and 8 others do not have significant area difference. Based on the tolerance of National Land Agency, among 11 parcels studied, there are 8 parcels that fullfill the tolerances and three others do not fullfill tolerances. The percentage of area difference average between land registration map and orthophoto is 4,72%. The result shows that the differences in boundaries and areas that may be caused by a systematic error of method in describing the boundaries of the ground.
