Classification: CPC G  A | IPC A  G

Claim 9:
10. A control method of a distance measuring apparatus, comprising:
acquiring, by a location acquiring sensor, a current location of the distance measuring apparatus;
reading out, by a control unit, map information of golf courses corresponding to the current location from a memory in which the map information of the golf courses is stored;
measuring, by a distance measuring sensor, a distance to a target;
measuring, by a slope sensor, a sloped tilt angle;
measuring, by an azimuth sensor, an azimuth to which the distance measuring apparatus is directed;
calculating, by the control unit, a horizontal distance to the target by using the distance to the target and the tilt angle;
calculating, by the control unit, a first distance from the current location to a first point of the golf course;
determining, by the control unit, whether the horizontal distance is within the first distance;
determining, by the control unit, whether the azimuth is included in a range between a first azimuth in a direction connecting a second point of the golf course from the current location and a second azimuth in a direction of connecting a third point of the golf course from the current location, wherein the second point of the golf course and the third point of the golf course are different from a point of the target; and
outputting, by the control unit, the horizontal distance when the horizontal distance is within a first distance and when the azimuth is included in the range between the first azimuth and the second azimuth.
