Abstract

PURPOSE:To easily generate a drawing by putting four faces, which are described with a road generating means, a graphic generating means, a character writing means, and a locus drawing means, one over another to synthesize them into one character and graphic plane. CONSTITUTION:A road generating means 8 draws roads, rivers, railroads, subways, tunnels, footbridges, intersections of them, and terminals of them on one face. A graphic generating means 15 draws graphics on its private plane and paints out the closed section, which is surrounded with these graphics, with plural patterns. A character writing means 19 writes characters in prescribed coordinate positions on its private plane and writes map symbols. A locus drawing means 22 draws a locus on its private plane while tracking a material like a cursor which designates a position. These four planes are synthesized by a drawing synthesizer 6 and a synthesized part cut-off device 7 and are displayed on a display device 2.

[Example] Here, the present invention will be explained based on an example showing details of the present invention.

FIG. 1 is a diagram showing a schematic map creation device of the present invention. Reference numeral 1 in the figure is an input device for manually inputting characters, processing instructions, and display coordinate positions. Data input by the human input device 1 is classified into three types: commands and character input/display coordinates, and is sent to the command analysis device 3, character input device @4, and display coordinate analysis device 5, respectively. The command analysis device 3 analyzes the processing contents, and sends the contents to each device for predetermined processing.The characters input by the character input device 4 are sent to the character drawing and editing device 20, and the display coordinate analysis device The coordinate data analyzed by 5 is used for predetermined processing of each device.

In the road creation means 8, a road drawing device 10 draws various roads, a river drawing device 13 draws various roads, a railway drawing device 11 draws various railways, a pedestrian bridge drawing device 14 draws pedestrian bridges, and intersections are drawn on the dedicated plane. By both devices 9,
These intersections are drawn, and the end shape of these ends is drawn by the end drawing device 12.

Plane e is a plane exclusively used for the road creation means 8, plane d is a plane dedicated for the figure creation means 15, plane S is a plane dedicated for the character description means 19, and plane a is used for the road creation means 22. It is a dedicated plane.

Furthermore, the plane C is considered as the plane of the composite partial blocking device 7, and α in the figure is an area where planes d and e are made blank, and areas other than α on the same plane transmit the data of planes d and e. It is a part.

Therefore, the drawing/synthesizing device 6 synthesizes the five planes a, b, c, d, and c to create one plane A.

[Effect of the invention] The present invention has the following effects.

(1) You can draw a figure without being aware of the blank area in advance, specify the area where you want to draw a necessary comment, handwritten picture, etc., and make the figure in that area blank, which simplifies the work.

(2) The blank area can be returned to its original state by releasing the designated area, making it easy to edit.

(3) An area that has been blanked out will return to its original state by releasing the designated area, and an area that has been blanked out due to an erroneous operation can be easily restored to its original state.
