SURVEYING ASSISTANCE PROGRAM, SURVEYING ASSISTANCE DEVICE, SURVEYING ASSISTANCE METHOD, AND SURVEYING ASSISTANCE SYSTEM

The present invention provides a surveying assistance method with which observations of a center stake distance and an as-built part can be assisted. The surveying assistance method is a surveying assistance method, wherein a computer (50) reads design information including center point data of center points set on a centerline of a route and constituent point data of constituent points set on sections including the center points, the section being orthogonal to the centerline, acquires position information indicating a current position of a surveyed device (40) at a predetermined period, calculates a horizontal distance and a vertical distance between the current position and a reference point on a designated section based on the position information and the design information, displays the horizontal distance and the vertical distance on a display unit of the computer as survey information, and updates the display at intervals of the predetermined period, and the reference point is a point to be selected from the center points or the constituent points.
