Key words: Total Station Road measuring techniques 1 Total station in the wire measurement Total Station Coordinate the advantages of Total Station can be used directly with the measuring point coordinate method, rather than polar coordinates law required, so that heavy equipment operators from the calculation of the data out. Outside the industry are now virtually no records, only a simple mind and the next point with the point of the relationship between the finishing industry for the reference period, but also do not have staff with a record of the calculation. Finishing in a time when the industry as long as the data transmission from the total station to PC2E500 calculator, or directly to the data input to a puter, after coordinate adjustment, on the puter using Auto CADdrawing software such as points, cutoff point, and calculated the angle value of each curve, the distance between the point of intersection as well as the coordinates of each pile and so. Note and the application of statecontrolled threedimensional coordinates of points Coordinates method used before, as far as possible the country to find control points and control points of these threedimensional coordinates, and these control points through the joint test, not only can test their measurement accuracy, and erroryun Xu scope can be carried out through the adjus
