Then, the actually measured linear distance R obtained from this measurement data is output to the computer 6. Other configurations are the same as those in the first embodiment except that the memory card 7 does not store the position altitude data (X, Y, Z) of the measurement pile.

The operation of the distance measuring device having the above structure will be described. When the power of the distance measuring device is turned on, for example, as shown in FIG. 11, the first distance measuring routine is executed and the input request of the hall number is displayed on the display unit 1. . When the hole number currently played by the golfer is keyed in according to the input request (S21), the No. 1 storage area storing the data matching the hole number is searched. When the search is completed, data is read from the group of storage areas No. 1 to 10 including the corresponding storage area No. 1, and as shown in FIG. 9, the pin 10, the green 11, the bunker 13 ..., the pine tree, etc. Other target objects 14 of ... are displayed on the screen of the display 1 together with the plan view of the hall (S

Thereafter, the calculated linear distance Rij is subtracted from the measured linear distance R obtained by the distance sensor 16,
It is determined whether or not the absolute value of the subtraction value is smaller than the distance variable dR (S38). As a result, when it is determined that the value is small, S40 is executed as NO. On the other hand, when it is determined that the value is not a small value, the absolute value obtained by subtracting the calculated linear distance Rij from the measured linear distance R is substituted into the distance variable dR, and the first coordinate variable i · j is set as the second coordinate variable I. -After being substituted for J, S40 will be executed.

Next, in S40, 1 is added to the coordinate variable i (S40), and the added coordinate variable i is the final value (M + 1) obtained by adding 1 to the coordinate value M of the final point. It will be determined whether or not (S41). Then, if it is determined that they do not match,
As a result of NO, S34 is re-executed, and execution of S34 to S40 is repeated until the coordinate variable i matches the final value (M + 1).

When the coordinate variable i matches the final value (M + 1), 1 is added to the coordinate variable j (S4
2) Then, it is determined whether or not the added coordinate variable j matches the final value (N + 1) obtained by adding 1 to the coordinate value N of the final point (S43). If it is determined that they do not match, NO is substituted for “0” in the coordinate variable i (S44), and S34 is re-executed, so that the coordinate variable j becomes the final value (N + 1). The execution of S34 to S42 is repeated until they match.

Data and a storage unit that stores the position altitude data of the measurement target position, and a distance sensor that measures a linear distance from the measurement position to the measurement target position, and the measurement target position of the measurement target position obtained by the azimuth sensor. A configuration in which the positional relationship is obtained by obtaining the position altitude data of the point corresponding to the measurement position based on the azimuth, the position altitude data of the measurement target position, and the straight line distance obtained by the distance sensor. Therefore, the positional relationship can be obtained by a single operation of the distance measuring device, so that the operability is improved.

Further, as described above, in the distance measuring device according to the eighth aspect, the control means according to the third, fourth or fifth aspect further includes an arbitrary point in the plan view displayed on the display means. Is designated and displayed as the second measurement target position. The position altitude data of the point corresponding to the second measurement target position designated by the designation unit is obtained, and the second measurement target position is obtained. Also, the linear distance, the horizontal distance, and the altitude difference between the measurement positions are obtained and displayed on the display screen of the display means.
As a result, it is possible to obtain the linear distance, horizontal distance, and altitude difference from the measurement position at any position within the predetermined area, so that the situation and positional relationship around the measurement position and the measurement target position can be grasped more accurately. The effect is that it is possible.

As described above, the distance measuring device according to claim 9 is configured such that the control means according to claim 1 can switch the display screen of the display means between a plan view and a vertical sectional view. Therefore, even if the predetermined area including the measurement position and the measurement target position has a rugged topography such as a golf course or a mountaineering field, the positional relationship can be accurately grasped.
