DIAGRAM REDUCING COMPILING METHOD AND DEVICE AND DIAGRAM DEFORMING DEVICE AND METHOD

摘要

PROBLEM TO BE SOLVED: To automatically deform a house shape in an easy-to-see shape according to reduction in a map.;SOLUTION: A circumscribed rectangle setting device 14 of a removal determining device 12 sets a circumscribed rectangle in input house data 10. A comparator 16 compares the short side of the rectangle set by the rectangle setting device 14 with the reference length La, and outputs only the house data having the short side not less than the reference length La to a rear stage. A deforming device 18 simplifies the shape by repeating deformation until the shortest side of the house data from the removal determining device 12 becomes the reference length Lb or more. A reducing device 20 reduces the house data of simplifying the shape by the deforming device 18 to the size a little smaller than the size simply reduced to an objective contraction scale.;COPYRIGHT: (C)2003,JPO
