In this embodiment, by using the website of the Geospatial Information Authority of Japan as the terrain information site 32, three-dimensional digital data such as terrain (undulations and shapes of the ground surface) is obtained.

[0031] (Construction support process) The construction support process will be described with reference to FIG. 3. Here, first, the control unit 21 of the management server 20 executes a specific process for the work content (step S11). Specifically, the administrator designates the construction plan information recorded in the construction plan storage unit 22 using the management device 10.
