PROBLEM TO BE SOLVED: To provide an acquiring method, an acquiring device, and an acquiring system for positioning data of higher accuracy by using a GPS. SOLUTION: This acquiring system for positioning data comprises a GPS receiver and a positioning data processor. On a display part 7 of the data processor, positioning points P2 corresponding to a plurality of groups of positioning data obtained at the same point and an average positioning point P1 corresponding to the average value of the positioning data are displayed on a positioning-point distribution chart Z. Positioning data to be excluded from calculating objects in calculating the average value of the positioning data are determined by designating an average object positioning point P2 imprinted on the distribution chart Z and taking it as an average exclusion positioning point P3. Thereafter, a new average value is calculated with positioning data corresponding to singular points excluded from calculating objects. A positioning person acquires this average value of the positioning data as positioning data on a positioning spot. COPYRIGHT: (C)2007,JPO&INPIT
