Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
In this programme, map symbol according to its expressed different terrestrial object information types, is divided into point symbol, line symbol, three types of Classification Managements (the suffix name with different is distinguished) of carrying out symbolic library of face symbol.The user can create and define a new symbol in the symbol making instrument, also can edit the pattern and the association attributes of existing symbol.Simultaneously, the map color is carried out unified management with the form of color libraries, adopt the color management mode of " CMYK " four looks, and the editting function to special look is provided, can satisfy the specific demand that some maps are published the user like this.
Method embodiment
As shown in Figure 1, geography information symbol processing method embodiment of the present invention comprises:
Step 108 is preserved said geography information symbol, and in electronic chart, is loaded.
The geography information symbol processing method of present embodiment upgrades administrative mechanism through adopting unified symbolic library, has formed the comparatively perfect symbol making flow process of a cover, and editor and operating function to dissimilar symbols such as vector, grid, Truetype are provided.
Create after the geography information symbolic library, in the upper layer application system, can use notation through following mode:
1, loads the point, line, surface symbolic library under the assigned catalogue through interface
2, enumerate all symbols below the point, line, surface symbolic library through interface
3, select the interface through the interface interchange symbol, show all symbols in the current sign storehouse, and allow the user to select some symbols, and obtain the classification coding and the ID of selected symbol through mouse.
4, can directly quote these symbols through interface, obtain more specifying informations of symbol, comprise according to the classification coding and the ID of symbol:
The symbol main classes is not encoded, symbol ID, symbol acquiescence height, symbol acquiescence width, symbol level interval, symbol vertical interval, the symbol anglec of rotation, face sideline width, symbol color numbering, designation, fill color, face sideline Vehicle;
5, can point of invocation symbol plotting interface, directly import point coordinate into, graphical pointv symbol on the map platform
