Geoid undulation prediction using ANNs (RBFNN and GRNN), multiple linear regression (MLR), and interpolation methods: A comparative study
Konakoglu, Berkant; Akar, Alper (Univ Nacional De Colombia, 2021)This study evaluated different methods for geoid undulation prediction and included two types of artificial neural networks (ANNs) -the radial basis function neural network (RBFNN) and the generalized regression neural ... -
GEOID UNDULATION PREDICTION USING GAUSSIAN PROCESSES REGRESSION: A CASE STUDY IN A LOCAL REGION IN TURKEY
Konakoglu, Berkant; Akar, Alper (Acad Sci Czech Republic Inst Rock Structure & Mechanics, 2021)In order to convert ellipsoidal heights obtained by the Global Navigation Satellite System (GNSS) to orthometric heights, it is necessary to know the distance between the ellipsoidal and geoid surface, called the geoid ... -
Investigation of the Effects of Tectonic Movements Occurring in Elazig and Surrounding Provinces on the Positions of TNPGN-Active Stations by Using Static Deformation Models
Konakoglu, Berkant; Akar, Alper (Geomatik Journal, 2021)Turkish National Permanent GNSS Network-Active ( TNPGN-Active) Project serves their users with a total of 158 permanent stations, including the Turkish Republic of Northern Cyprus and Turkey. The movements caused by ... -
Prediction of geoid undulation using approaches based on GMDH, M5 model tree, MARS, GPR, and IDP
Konakoglu, Berkant; Akar, Alper (Springer, 2022)This study provides a comprehensive comparison of four different machine learning models including the group method of data handling (GMDH), M5 model tree (M5MT), multivariate adaptive regression spline (MARS), and Gaussian ... -
Prediction of geoid undulations: Random forest versus classic interpolation techniques
Akar, Alper; Konakoglu, Berkant; Akar, Ozlem (Wiley, 2022)Local geoid determination studies are commonly carried out today to establish the relationship between the ellipsoidal height (h)$$ (h) $$ determined by satellite geodesy methods and the orthometric height (H)$$ (H) $$ ...
