Information processing method, program, and information processing system

An information processing system, comprising:

• a plurality of observation apparatuses configured to execute simultaneous observation based on signals received from a global navigation satellite system satellite;
• an information acquisition unit configured to acquire position information associated with installation points of the observation apparatuses based on the signals received by the observation apparatuses, and position information associated with a known control point;
• and
• an automatic generation unit configured to generate, by a processor, a check network based on a first automatic generation algorithm by using the position information associated with the installation points of the observation apparatuses acquired and the position information associated with the known control point.
