PROBLEM TO BE SOLVED: To make work remarkably efficient by acquiring simply and quickly coordinate information directly through no network in a site or a field, and by processing immediately information based on the coordinate information such as survey work and observation work. SOLUTION: This geometric information processing system is provided with a two-dimensional code 1 for coding and storing the coordinate information of a measuring point with the preliminarily specified coordinate information, and fixed to the measuring point, and a mobile terminal device 10 for executing prescribed information processing, based on the coordinate information stored in the two-dimensional code 1. The mobile terminal device 10 has reading-in means 11, 12 for reading the two-dimensional code 1 in to output the corresponding coordinate information, and computes and outputs geometric information including at least one information out of a distance, an azimuth, an angle and an area defined by the measuring points, based on the coordinate information of the plurality of measuring points read in by the reading-in means 11, 12.
