RISTransformation of Cartesian to Geodetic Coordinates without Iterations
Publisher: American Society of Civil Engineers
Abstract: A noniterative transformation of earth-centered, earth-fixed (ECEF) Cartesian coordinates to geodetic coordinates of a point is presented. The transformation is based on ellipsoidal coordinates. The ECEF Cartesian coordinates ...
Local Geoid Improvement Using GPS and Leveling Data: Case Study
Publisher: American Society of Civil Engineers
Abstract: National leveling height networks have recently been set up in Taiwan, and global positioning system (GPS) observations were carried out at the benchmarks of the networks. The purpose of this paper is to develop an improved ...
Coordinate Transformation between Two Geodetic Datums of Taiwan by Least-Squares Collocation
Publisher: American Society of Civil Engineers
Abstract: Recently, the new Taiwan geodetic datum 1997 (TWD97) based on the Global Positioning System measurements has been established. Compared to the old geodetic datum, namely the Hu-Tzi-Shan datum, the TWD97 datum is more ...
