Geodetic survey method according to the change of terrain by reference point

摘要

The present invention relates to a geodetic survey method according to a change in topography for each reference point, and in more detail, as well as a change in topography due to urban development, as well as a measurement of defects due to the fact that the reference point cannot be confirmed due to a ground sink or ice and snow around the reference point. It relates to a geodetic survey method according to the terrain change for each reference point, which has been improved to enable accurate and stable geodetic survey of aircraft by removing the obstructive factors of geodetic survey.
