Abstract
The invention discloses a kind of map boundaries to jump the method painted automatically, and compared with prior art, the boundary symbol of each grade of the present invention makes and can be completed by standardized symbols and drawing expression symbol two ways.In order to show, symbol is painted in the left jump of boundary and symbol is painted in right jump, the making symbol expressed using drawing.Symbol is painted in left jump and right jump to paint symbol be along jumping the boundary line painted by starting point to the end direction, it is that symbol is painted in right jump on the right of direction, it is that symbol is painted in left jump, and takes the upper parallel lines of boundary line and lower parallel lines according to the offset distance of drafting manual on the direction left side.Efficiency is improved, is had the value of popularization and application.
Description
Technical field
The present invention relates to map boundary line method for drafting more particularly to a kind of map boundary to jump the method painted automatically.
Background technology
Drawing norm requirement according to the map, when drawing boundary, when being boundary with linear ground object (such as water system, traffic),
Boundary is along linear ground object between left and right every drafting.Tradition boundary compilation method is manually to edit at present.Traditional boundary compilation side
Method causes boundary jump to be painted uneven, jump is painted apart from nonstandard, inefficiency by manually editing.
Invention content
The purpose of the present invention is that provide a kind of map boundary to solve the above-mentioned problems jumps the method painted automatically.
The present invention is achieved through the following technical solutions above-mentioned purpose：
The present invention existing original boundary line, linear ground object geographic information database on the basis of, in conjunction with GIS technology reality
The automatic jump of existing boundary is painted, and is as follows：
(1) according to province, city, county, town formulate respectively it is left jump paint boundary symbol, it is right jump paint boundary symbol, do not jump paint boundary symbol
Number；
(2) GIS attribute query methods are based on, original boundary line is extracted according to province, city, county, town, union space merges
For 4 whole boundary lines；
(3) it will need, according to the geographic element that linear ground object is border, to be extracted according to GIS attribute query methods；
(4) province, city, county, town boundary line and linear geographical essential factors space are asked into friendship, is intersected as a result, intersecting result i.e.
The boundary painted to need left and right to jump；
(5) it is that not jump to paint the result space of province, city, county, town boundary line and intersection to be sought different obtained different result of asking
According to center line draw boundary；
(6) intersection result is carried out jumping the segmentation for painting section, jump is painted section and by several groups boundary symbol (claimed：Real part) and jump paint and stay
White section (claims：Imaginary part) composition；
For the ease of being described below, definition intersection result length is GeoLength, and real part is long
Degree is SolidLength, and imaginary part length is BlankLength, and it is as follows that section segmentation principle is painted in specific jump：
(7) intersecting result length divided by real part adds imaginary part length to obtain jumping and paint hop count；Successively according to space topological operation
Section boundary is drawn to each jump, corresponding geometry line segment is intercepted according to real part length；Then the odevity sequence of section is painted according to jump,
The left and right side of assignment, which is jumped, successively paints symbol；
(8) until all intersection processing are completed.
The beneficial effects of the present invention are：
The present invention is that a kind of map boundary jumps the method painted automatically, compared with prior art, the border of each grade of the present invention
Boundary's symbol making can be completed by standardized symbols and drawing expression symbol two ways.Symbol is painted in order to show the left jump of boundary
Number and it is right jump paint symbol, using drawing expression making symbol.Left jump paint symbol and right jump to paint symbol be along the boundary painted of jump
Line is that symbol is painted in right jump on the right of direction by starting point to the end direction, on the direction left side is that symbol is painted in left jump, and according to
The offset distance of drafting manual takes the upper parallel lines of boundary line and lower parallel lines.Efficiency is improved, is had the value of popularization and application.
Description of the drawings
Fig. 1 is that the present invention jumps the schematic diagram before painting as boundary using water；
Fig. 2 is that the present invention jumps the schematic diagram after painting as boundary using water.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2：The present invention is on the geographic information database basis of existing original boundary line, linear ground object
On, it realizes that the automatic jump of boundary is painted in conjunction with GIS technology, is as follows：
(1) according to province, city, county, town formulate respectively it is left jump paint boundary symbol, it is right jump paint boundary symbol, do not jump paint boundary symbol
Number；
(2) GIS attribute query methods are based on, original boundary line is extracted according to province, city, county, town, union space merges
For 4 whole boundary lines；
(3) it will need, according to the geographic element that linear ground object is border, to be extracted according to GIS attribute query methods；
(4) province, city, county, town boundary line and linear geographical essential factors space are asked into friendship, is intersected as a result, intersecting result i.e.
The boundary painted to need left and right to jump；
(5) it is that not jump to paint the result space of province, city, county, town boundary line and intersection to be sought different obtained different result of asking
According to center line draw boundary；
(6) intersection result is carried out jumping the segmentation for painting section, jump is painted section and by several groups boundary symbol (claimed：Real part) and jump paint and stay
White section (claims：Imaginary part) composition；
For the ease of being described below, definition intersection result length is GeoLength, and real part is long
Degree is SolidLength, and imaginary part length is BlankLength, and it is as follows that section segmentation principle is painted in specific jump：
(7) intersecting result length divided by real part adds imaginary part length to obtain jumping and paint hop count；Successively according to space topological operation
Section boundary is drawn to each jump, corresponding geometry line segment is intercepted according to real part length；Then the odevity sequence of section is painted according to jump,
The left and right side of assignment, which is jumped, successively paints symbol；
(8) until all intersection processing are completed.
The boundary symbol of each grade, which makes, to be completed by standardized symbols and drawing expression symbol two ways.For
It can show that symbol is painted in the left jump of boundary and symbol is painted in right jump, using the making symbol of drawing expression.Symbol is painted in left jump and right jump is painted
Symbol is along jumping the boundary line painted by starting point to the end direction, is that symbol is painted in right jump on the right of direction, on the direction left side
It is that symbol is painted in left jump, and takes the upper parallel lines of boundary line and lower parallel lines according to the offset distance of drafting manual.
The basic principles and main features and advantages of the present invention of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
