The Design of L3D-HEIGHT Program for Orthometric Height Determination Using GPS And Terrestrial Geodetic Data

Abstract

The Global Positioning System (CPS) produces, in phase measurement mode, very accurate three-dimensional Cartesian coordinates differences between obsPTVation points. Therefore, for many applications, this three-dimensional capability has the potential of replacing costly and time-consuming spirit levelling in height determination, especially when a large or a remote unsurveyed area is involved. For this purpose, a computer program called L3D-HEIGHT was developed to act as a tool in processing for 3D coordinates and orthometric height determination using GPS and other terrestrial geodetic observable. This paper describe the basic structure and primary features of the program.
