APLIKASI METODE POLINOMIAL LEAST SQUARE BERBASIS MATLAB UNTUK MEMISAHKAN EFEK RESIDUAL ANOMALI REGIONAL PADA DATA GRAVITASI

Abstract

Data of Bouguer anomaly consist of superposition of local and regional components. Seperation has been done to obtain local and regional anomalies which not influence one to another so the interpretation could be taken more accurately. Polynomial Least Square under MATLAB was applied to separate local – regional anomalies. The result showed that second order polynomial is the best order which has been choosen to estimate the regional data anomaly of gravity data for study case in Bandar Lampung, and the interpretation has resulted good local anomaly.
