  • This paper focuses on examining and evaluating results of the Korean Geodetic Datum 2002 (KGD2002) of the national horizontal network adjustment. To this end, 137 geodetic control points were independently observed by GPS technology. After processing all the observations, their results were compared with ones derived by the national network adjustment which was recently performed to determine new KGD 2002 coordinate sets over the national geodetic control points. The comparisons results showed that RMSE was ${\pm}2.7cm$ and ${pm}6.5cm$ in horizontal and vertical component in the case of GPS network, whereas RMSE was ${\pm}3.0cm$, in horizontal component in the case of EDM network.

  • This is the study to investigate the Algorithm of BRI 2002 which is high level estimation program of smoke movement and phenomenon for performance based of design named 'ROOT C', made by Japan. BRI2002 is composed of 3 parts, one is main program, and the others are 4 subroutines and blockdata. The aim of this study is to analyze the BRI 2002, the only one certified program for the P.B.D and compare the other common program for smoke movement simulation program.
