<p>The present invention relates to a land survey data measuring apparatus for confirming a point to point route change using GPS information. The present invention comprises an upper support; three legs having upper ends coupled to the upper support to be rotatable and installed to be widened and closed; a three dimensional rotation support unit supporting the measuring device mount to be three dimensionally rotatable with respect to the upper support; a gradient sensing unit installed in the measuring device mount to sense a gradient of the measuring device mount; a mounting device mount horizontality maintaining unit automatically maintaining the measuring device mount in a horizontal state according to a gradient sensed signal of the gradient sensing unit; a controller embedded within a control box installed on the bottom of the upper support; and a power supply unit supplying power to the gradient sensing unit, the measuring device mount horizontality maintaining unit and the controller. The present invention, if the legs are unfolded and stand on the ground, automatically maintains the top of the measuring device mount in a horizontal state by the measuring device mount horizontality maintaining unit such that, if the tripod is installed and then the measuring device is disposed on the measuring device mount, it maintains the measuring device in a horizontal state, thereby rapidly performing processes of installing the tripod and measuring the land survey data.</p> |
