PROBLEM TO BE SOLVED: To make clear a dispersion state of environmental pollutants without displaying an unmeasured area in a measured manner, in a creating method for an environmental pollution isoconcentration map. SOLUTION: This system is equipped with a detecting means for detecting the concentration of the environmental pollutants distributed within a specific area. A map of the specific area is displayed on a display means of a computer, the concentration of the pollutant at least one point in the specific area is measured by the detecting means. The concentration at a point apart from the measuring point by a prescribed distance is deemed to be not detected, and the concentration at the measuring point is divided in a prescribed range. Ranges showing the same concentration among the divided ranges are connected to display isoconcentration lines on the map on the display means. Thus, the unmeasured area is prevented from being displayed in a measured manner, thereby making clear the dispersion state of the environmental pollutants. COPYRIGHT: (C)2004,JPO
