PURPOSE:To display the height of a facility and to discriminate the adjacent degree of facilities by adding a device to convert the information of the height to the gradation of colors and to display it. CONSTITUTION:Map data 1 are provided with data h16 of the height, power system facility data 2 are provided with data h27 of the height, and a display controller 4 is provided with data Dh8 of the height. A display controller 8 inputs the data h1 of the height of the map data and the data h2 of the height of the power system facility and decides the tone corresponding to the height. In this case, while using an upper limit value hmax of the data of the height, lower limit value hmin, color tones Cmax and Cmin corresponding to those values, when the h1 and h2 are larger than the hmax, the Cmax is decided as the color tone, when the h1 and h2 are smaller than the hmin, the Cmin is decided as the color tone and when the h1 and h2 are the middle value from the hmax to the hmin, calculation shown by the formula is executed. In this formula, the (h) is h1 or h2. Then, the color tone of a display terminal 5 close to the calculated value is defined as the color tone for display and displayed through the display controller 4. |
