摘要

[Problem] To provide a system for displaying the degree of safety of ground, said system being capable of providing a user with ground data for a current location and even a location distanced in any direction from the current location, in an easy-to-understand manner. [Solution] A system for displaying the degree of safety of ground is provided with a degree-of-safety server and a mobile terminal. The degree-of-safety server is provided with: a soil improvement database which stores, for each of a plurality of sets of location information, information about whether or not soil improvement work is necessary; and a server control unit which searches the soil improvement database on the basis of location information, calculates a soil work score, and calculates the degree of safety of ground on the basis of the soil work score. The mobile terminal is provided with an input/output unit, a location acquisition unit, a direction acquisition unit, an attitude acquisition unit, an image capture unit, and a control unit which: calculates, as acquired location information, location information about a surface of ground toward which the image capture unit is oriented to capture an image, on the basis of current location information acquired by the location acquisition unit, a direction acquired by the direction acquisition unit, and attitude information acquired by the attitude acquisition unit; acquires the degree of safety of the ground from the degree-of-safety server on the basis of said acquired location information; and outputs the degree of safety of the ground to the input/output unit.
