Determining the maritime baseline for marine cadastre
Robin Seet, Dr David Forrest and Dr Jim Hansom
The primary aim of this research is to develop a methodology to efficiently determine the baseline by acquiring an integrated terrestrial Digital Terrain Model (DTM) using DGPS and a marine DTM based on near-shore bathymetry and tidal data, in order to derive the location of the baseline at a particular time....

On the transformation of time system in relativity based on SOFA and .NET
Shenquan TANG , Jianan WEI and Erhu WEI
According to assembly of the transformation of time system in relativity provided by Standards Of Fundamental Astronomy (SOFA), the defi nition of time system in relativity and its transformation are investigated. The mixed programming technology between .NET language and FORTRAN language are used to analyze the transformation process of assembly and to realize interface of transformation of time system...
