【発明の名称】地表面形状表示処理方法
Document Type and Number:
Japanese Patent JP2688027
Kind Code:
B2
Abstract:
PURPOSE:To improve the reality of a view drawing by working for rounding the height values of respective grating points expressing a ground surface with a prescribed interval, correcting fractions and finding out differences in levels and adopting the worked result as the view drawing. CONSTITUTION:The height values of respective grating points expressed by prescribed three-dimensional(3-D) data 1 for the grating points set up in a prescribed area are corrected 2 by prescribed rounding in each grating point at a prescribed interval in the specified area. The view drawing is formed 4 based upon the corrected 3-D data 3. In the formation of the view drawing by means of a computer, comparatively natural level differences can be formed on a ground surface by level difference work based upon comparativel simple processing 2 and the reality of the view drawing can be economically improved.
