BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surveying and drawing system capable of completing a topographic map at a surveying site using a computer.

[0002]

2. Description of the Related Art As is well known, a surveying method for preparing a topographic map includes an aerial surveying method and a ground surveying method, and the latter is roughly classified into a flat plate method and a numerical method. In a general procedure of this numerical method, first, a feature is observed as relative polar coordinates using a light wave angle range finder or the like, and the value is recorded in a field note or an electronic field note. After returning to the office, the recorded measurement results are converted into absolute rectangular coordinates using a computer or the like, plotted on paper at an appropriate scale, and point information, connection information, etc., corresponding to the feature. Is filled in with a pencil to complete the figure below, and tracing is performed based on this.

[0003] Such a numerical method has advantages such as higher accuracy than the flat plate method, no necessity of actually measuring the distance with a tape measure, and a wide observable range from one base point. There is a problem in that the situation of the site is input by the memory of the person at the time of completion, and it is likely to be inaccurate. Moreover, since the lack of the observation information is found after the topographic map is formed, the site work is required again.

[0004]
