Transformasi Koordinat menggunakan Jaringan Syaraf Tiruan Propagasi Balik Resilient (Studi Kasus: Daerah Sumatera Bagian Selatan)

Abstract

Genuk Datum and World Geodetic System 1984 (WGS’84) are used as geodetic reference frames in Indonesia. To fully utilize the technology of WGS’84, it is necessary to transform twodimensional (2D) coordinate data from Genuk to WGS’84. The four-parameter similarity transformation method is frequently used for 2D coordinate transformation in geodesy. In this study, Resilient Backpropagation (Rprop) model is evaluated as an alternative 2D coordinate transformation method. Rprop is compared with four-parameter similarity transformation over a test area in terms of mean square error. The result indicates that the employment of Rprop transformed 2D coordinate (x, y) is more accurate than four-parameter similarity transformation and can be useful for 2D coordinate transformation between Genuk and WGS’84.
