No.304 triangulation point which is placed the mountain at the 
back of Habpo high school was used as a base. N0.404 
triangulation point at Bium-pass in Gapo and no.405 
triangulation point at Yongmasan park were used as rovers and 
the black point of GPS survey. We set six points out in 
Kyungnam University for rovers and operated GPS survey.
