Pełny opis

This book begins with an introduction to GPS height conversion method, including polynomial surface fitting, multi-surface fitting function, BP networks and remove, fit and restore method, etc. And deeply introduces optimization model formfitting considering of AIC. Then the book introduces sub-areas fitting approach, firstly, remove high precision of long wavelength contributions, and EGM96 is a gravity model of the earth, which has high precision of long wavelength contribution, topographic correction is to reflect the medium-wave characteristics of the geoid. Remove the long wavelength or topographic correction from GPS/leveling points, next construct a model from the leaving parts fitted by BP neural network to calculate other GPS points, and restore the long wavelength or topographic correction to the points. Finally, this book introduces conversion method of GPS heights considering weighted moving mean moving-surface fitting, Voronoi K order adjacency, management of ArcObjects, and gross error detection.
