PROBLEM TO BE SOLVED: To enable economical position correction and compression of record data amount with a small workload, by dividing the display form (display color) of measured data of a plurality of points, in accordance with measured values, and replacing every part where the display form is continuous with a segment. SOLUTION: A data display part 3 divides (quantizes) the physical quantity measured on a vehicle into a plurality of levels, assigns a color or symbol to every division, color-codes the quantity, and display it with symbols, at the position expressed by position data on a displayed background map. A data operation part 4 forms a line connecting two points selected by an operator, and displays it on an image display 1. When all of the point data between the two points have the same color, the segment designates its color. When the point data color changes in the middle part, the segment is divided by the ratio of the points different in color, and colors corresponding to the point data are imparted. By repeating the above operation, a plurality of segments are formed and compared with the background map. When correction is necessary, the position of the segment is changed. |
