Analysis of Geometric Accuracy of Pleiades Satellite Images for Base Map RDTR (Case Study: Mojosari Sub-District, Mojokerto District)

Abstract

Mojosari Sub-district based on Local Government Regulation of Mojokerto District Number 9 Year 2012, concern of Spatial Planning for Mojokerto District 2012-2032 was proposed as the central government and service area of Mojokerto District. With the submission, Mojosari Subdistrict must have a good regional spatial use planning in the form of an Base Map RDTR with high accuracy. Therefore, the aim of this research is to analyze of horizontal accuracy of the pleiades satellite image, so that it can be used for making base map RDTR with a scale of 1: 5000. To produce a high-accuracy base map, the Pleiades satellite image must be processed and corrected geometrically in order to obtain an accurate image accuracy. In this study, geometric correction uses the Rational Polynomial Coefficient (RPC) method. Secondary data needed in this research are 12 points of GCP and 16 points of ICP which are measured using GPS Geodetic method, and administrative boundaries of Mojosari District. The strength of Figure obtained by the GCP points desaign is 0.546. From the results of the rectification process, the RMS Error value is 0.1 meters. To test the results of the rectification, the accuracy test was carried out using ICP with a horizontal accuracy of 1.5175 x RMSE. The accuracy test obtained a result of 0.095 meters. From the results of the horizontal accuracy of the Pleiades 1B satellite imagery, it has met the requirements to be used as an RDTR base map with a scale of 1: 5000 and class 1.
