The virtual position mapping unit 132 according to the present invention confirms the virtual position point 103 of the measurer based on the position information provided from the GPS receiver 110 and outputs it to the map graphic generation unit 131, The divided map graphics 102 are displayed on the display unit 100. [0052] FIG. In FIG. 4, it can be seen that the virtual positional point of the measurer is located in the lower left side 102c of the four divided map graphic images 102. FIG. Since the virtual position point 103 is based on the position information, it can be known that the virtual position point 103 is the current position point of the measurer.

Next, the target point calculator 133 according to the present invention calculates the distance of the target position point from the virtual position point based on the position correction information provided from the VRS server 120. [ At this time, since the target position point 104 is based on the position correction information, the distance can be easily calculated from the current position point 103 of the previously known measurer.

Next, the target position mapping unit 134 according to the present invention further maps the target position point 104 calculated by the target point calculation unit 133 to the center of the divided map graphic. In other words, the target position point 104 is displayed in the center in the four divided map graphic images 102 as shown in Fig.

In this manner, it is preferable that the virtual position point 103 and the target position point 104 are displayed together on the map graphic image 102 and that the distance value calculated between the two points by the target point calculation unit 133 is also displayed Do.

This allows the measurer to fully comprehend the distance between his current position point 103 and the target position point 104 and to know precisely and easily the target point 104 to be actually measured.

Next, the compass generating unit 135 according to the present invention generates the compass information 105 based on the virtual position point 103 and the target position point 104 described above, and informs the measurer of the directionality 105a The directionality 105a is written in the compass plate information 105 and then displayed on the map graphic 102 by mapping. At this time, the directionality 105a of the compass plate information 105 may be displayed in the form of an arrow as shown in FIG.

Therefore, the measurer can clearly confirm the target position point through the pole marks of the arrow and the compass.

Finally, the control unit 136 according to the present invention includes the map graphic generation unit 131, the virtual position mapping unit 132, the target point calculation unit 133, the target position mapping unit 134, 135, and further controls the communication data flow between the GPS receiver 110, the VRS server 120, and the mobile terminal 130. In addition, The control unit 135 may refer to a microprocess control mechanism.

As described above, when the mobile terminal 130 is implemented in a user-friendly GUI screen form, it helps the novice who does not understand the measurement mechanism to easily know the position of the target point.
