Embodiment
Shown in figure 1, disclose an embodiment for the grille picture electronic chart of Geographic Information System, comprising: map image picture 10, electronic dimension scale assembly 11, grille picture formation component 12, vector database 13, map unit formation component 14.
Map image picture 10 is the map of taking photo by plane of a picture format.
Electronic dimension scale assembly 11 is set one group of engineer's scale differing in size.Different engineer's scales shows a region on map with different the level of details.As will be described below, the grille picture of the different corresponding different sizes of engineer's scale and the vector data of expression geography information.Table 1 has disclosed an engineer's scale
The example of classification, has disclosed under different engineer's scales to show which information.
Table 1
Grille picture formation component 12 is coupled to electronic dimension scale assembly 11, according to the maximum ratio chi of electronic dimension scale module sets, map image picture is cut into a series of basic grille picture adjacent to each other, by several adjacent basic grille picture splicings, form the grille picture of corresponding little one-level engineer's scale, by the grille picture splicing of large several correspondences one-level engineer's scale, form the grille picture of little one-level engineer's scale successively; Final formation corresponding to each a series of grille pictures in one group of engineer's scale.According to the present invention, first can be according to maximum engineer's scale, map image picture is cut into basic grille picture one by one by the i.e. requirement of the most detailed display mode, and more conventional mode is that map image picture is cut into the basic grille picture of rectangle adjacent to each other.Shown in figure 2, the unit 20 of each rectangle wherein represents a basic grille picture.For the engineer's scale of little one-level (in table 1,1:1000 is exactly the little one-level engineer's scale of 1:500), its shown scope is the combination of several large one-level engineer's scales, therefore, several adjacent corresponding grille pictures of large one-level engineer's scale are stitched together, have just obtained the grille picture of little one-level engineer's scale.For example, in embodiment shown in Fig. 2, grille picture 20,21,22,23 is all the grille picture corresponding to 1:500 engineer's scale, and 20 and 21 grille pictures that are combined to form or 22 and 23 grille pictures that are combined to form can be just the grille pictures corresponding to 1:1000 engineer's scale.It should be noted that, the array mode of grille picture is restriction not, can as required several grille pictures adjacent to each other be combined to form to the grille picture of little one-level engineer's scale.For example, the grille picture being made up of together four grille pictures 20,21,22,23 can be the grille picture corresponding to 1:2000 engineer's scale.By above-mentioned mode, final formation corresponding to each a series of grille pictures in one group of engineer's scale, for each engineer's scale, is stitched together a series of grille pictures corresponding with it, just can obtain complete map.
Vector database 13 is coupled to electronic dimension scale assembly 11, preserves one group of vector data, the corresponding engineer's scale of each group vector data, and vector data is electronic geographic-information.Mention above, the electronic chart with geography information comprises map picture and two parts of geography information, grille picture formation component 12 has generated map picture for each engineer's scale, and vector database 13 is for each engineer's scale is preserved corresponding vector data, i.e. geography information.The level of detail of the map that different engineer's scale shows differs, and therefore in vector database 13, the vector data of different scale is different type, such as, " displaying contents " in can reference table 1 designs the content of vector data.
Map unit formation component 14 is coupled to grille picture formation component 12 and vector database 13, map unit formation component 14 obtains a series of grille pictures of a corresponding engineer's scale, from vector database, extract the vector data corresponding to corresponding proportion chi, by this vector data and the stack of a series of grille picture, form a series of maps unit that should engineer's scale, this a series of maps unit is spliced into complete map according to grating map, forms electronic chart that should engineer's scale.Map unit formation component 14 is used to form a series of map unit of corresponding each engineer's scale.Such as, for the 1:500 engineer's scale in table 1, map unit formation component 14 can call grille picture 20,21,22,23 successively, and from vector database 13, obtain the vector data of corresponding engineer's scale 1:500, be geography information, then the vector data relevant to grille picture 20 be loaded on grille picture 20, the vector data relevant with grille picture 21 is loaded on grille picture 21, the vector data relevant with grille picture 22 is loaded on grille picture 22, the vector data relevant with grille picture 23 is loaded on grille picture 23.And for other engineer's scale of little one-level 1:1000, map unit formation component 14 can call 20 and 21 grille pictures that are combined to form, and obtain the vector data relevant to the grille picture of this combination, the common map unit generating corresponding to engineer's scale 1:1000.The like, map unit formation component 14 can generate a series of map unit for each engineer's scale, for each engineer's scale, relevant map unit spliced can be formed to complete map together.And the corresponding vector data of different engineer's scales is different.
The grille picture electronic chart so forming, in for user, can be according to user's selection and current engineer's scale, call corresponding picture element unit cell, compare with traditional mode, do not need to call overall data, also do not need to carry out calculating then and there, the speed of therefore calling can improve a lot.
In addition, in carrying out data upgrading, also can carry out take map unit as unit, and not need to change overall data, compare with traditional mode convenient a lot.
Shown in figure 3, the present invention has also disclosed a kind of grille picture map generalization method electronically for Geographic Information System, comprises following step:
30. maps of taking photo by plane that are retrieved as a picture format are as map image picture;
31. set one group of engineer's scale differing in size;
32. according to the maximum ratio chi of setting, and map image picture is cut into a series of basic grille picture adjacent to each other; Grille picture is generally rectangle;
33. by several adjacent basic grille picture splicings, form the grille picture of corresponding little one-level engineer's scale; By the grille picture splicing of large several correspondences one-level engineer's scale, form the grille picture of little one-level engineer's scale successively; Final formation corresponding to each a series of grille pictures in one group of engineer's scale;
34. preserve one group of vector data, the corresponding engineer's scale of each group vector data, and vector data is electronic geographic-information;
35. obtain a series of grille pictures of a corresponding engineer's scale, from vector database, extract the vector data corresponding to corresponding proportion chi, by this vector data and the stack of a series of grille picture, form a series of maps unit that should engineer's scale, this a series of maps unit is spliced into complete map according to grating map, forms electronic chart that should engineer's scale.
Concrete details can, with reference to the description to grille picture electronic chart above, no longer repeat herein.
Map is divided into map unit one by one by the present invention, and each map unit comprises take photo by plane accordingly map and geography information, for each engineer's scale, all has corresponding a series of map unit.In the time calling, can directly call according to selected engineer's scale the map unit having completed, after splicing, just obtain including the electronic chart of geography information, simultaneously, in the time that data need local upgrading, only need corresponding map unit to modify.
