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.
