<p>PROBLEM TO BE SOLVED: To display optimum property information among pieces of stepwise property information of meshes as display properties when a commercial zone is displayed. SOLUTION: Map data of an object area are divided into mesh data sectioned in a matrix shape and a reference point is set by making pieces of statical information correspond. Commercial zone information based upon the statistical information is calculated around the reference point by the meshes and displayed as 1st stage property information. Then 2nd commercial information based upon the statistical information is calculated around the reference point by the meshes and displayed as 2nd stage property information. On the basis of the 1st or 2nd stage property information by the meshes, the other is applied to a stage value to calculate a new stage value, thereby displaying the respective meshes in stages.</p> |
