• a setting unit for setting regarding a stereo image including at least three or more points of measurement having position data thereof obtained, at least a part of the points of measurement as division points, and then setting a search area based on at least three division points, and then setting a search area based on at least three division points selected from a plurality of the set division points;
• an arithmetic operation unit for executing correlation processing for images of search areas corresponding to each other on the stereo image based on the search area set by the setting unit;
• and
• a measuring unit for measuring a coordinate of a point in a given position based on a result of the correlation executed by the arithmetic operation unit, and
• a display unit for displaying a stereo image,
• wherein the arithmetic operation unit prepares information regarding an area of measurement where a new point of measurement is required, according to the result of the correlation processing,
• the display unit executes predetermined displaying for an area where additional measurement is required in a graphic manner according to the information of the area of measurement prepared by the arithmetic operation unit, and position data is received when the position data of the new point of measurement in the area is measured by an external survey instrument based on the graphic displaying of the display unit.
