Property.
It is to be understood that during icon shows in GIS map, can also enter after being loaded with GIS map
The various information processings of row, these information processings are for the process of GIS map it is also possible to be directed to the place of icon itself
Reason, is illustrated below in conjunction with wherein several specific examples.
The schematic flow sheet of the icon processing method carrying out during map scaling in a specific example is shown in Fig. 2.
As shown in Fig. 2 in the processing procedure carrying out map scaling, the method in this specific example includes step：
Step S201：Receive map scaling instruction, described map scaling instruction includes map scaling, enters step
S202；
Step S202：The current latitude and longitude information of each icon of display and the current window picture of each icon before record scaling
Plain coordinate, enters step S203；
Step S203：Window pixel coordinate model according to the current latitude and longitude information of described GIS map, described GIS map
Enclose, described map scaling, determine map scaling after described GIS map scaling rear hatch pixel coordinate scope, enter
Step S204；
Step S204：Obtain the scale attributes mark of each described icon, if the scale attributes of icon are designated with map contracting
Putting, then enter step S205, if the scale attributes of icon are designated not scaling with map, entering step S207；
Step S205：According to current window pixel coordinate, the described map scaling of described icon, to based on described figure
The length of described icon that target current window coordinate pixel determines and/or height zoom in and out, and obtain the scaling of described icon
Length and/or height, enter step S206 afterwards；
Step S205：Length and/or height, the scaling rear hatch picture of described GIS map after scaling according to described icon
Plain coordinate range, the current latitude and longitude information of described icon, obtain the map scaling rear hatch of the described icon after map scaling
Pixel coordinate, enters step S208；
Step S207：Keep the length of described icon of window pixel coordinate determination and/or the height based on described icon

S208；
Step S208：Map according to each described icon scales rear hatch pixel coordinate, and each described icon is contracted in map
Shown in described GIS map after putting.
Due to when zooming in and out, being not related to the change of the geographical location information to icon to map, therefore, it can no
The latitude and longitude information (i.e. the current latitude and longitude information of holding icon is constant) of icon need to be changed, only the window pixel of icon need to be sat
Mark is changed.When zooming in and out to map, although the latitude and longitude information of GIS map itself is unchanged, yet with ground
During figure scaling, latitude and longitude information changes in the pixel coordinate of current display screen, namely latitude and longitude information is sat with window
Mapping relations between mark pixel there occurs change, thus leading to the window pixel coordinate of each icon to change.
Therefore, the longitude and latitude letter of the latitude and longitude information to GIS map, icon can during map scaling, be not related to
The change of breath, only need to determine the mapping between the latitude and longitude information of GIS map and window coordinates pixel coverage after map scaling
Relation, you can determine the map scaling rear hatch pixel coordinate of each icon after map scaling.In a specific example, it is based on
Mapping relations between its original latitude and longitude information and window coordinates pixel, with one of pixel corresponding longitude and latitude letter
Point on the basis of breath, in conjunction with map scaling, you can determine what each latitude and longitude information of the GIS map after map scaling was mapped
New window pixel coordinate, and obtain the mapping relations between latitude and longitude information and window pixel coordinate after moving accordingly, enter
And can determine that the preliminary window pixel coordinate of each icon, then in conjunction with length after the scaling of this icon and/or height, you can really
The map scaling rear hatch pixel coordinate of fixed final each icon.It will be appreciated by those skilled in the art that can adopt any possible
Mode executes said process, and here is not reinflated to be repeated.
It is understood that the process for GIS map can also be included to the process in map moving process.
Therefore, in a specific example, the method in the embodiment of the present invention can also include：
Receive map move, described map move includes map moving direction and map displacement；
The latitude and longitude information of each icon of display and the window pixel coordinate of each icon before record is mobile；
According to load after described GIS map latitude and longitude information, load after described GIS map window pixel coordinate
Scope, described map moving direction, described map displacement, determine the described GIS map after the loading after map movement
Through latitude information and mobile rear hatch pixel coordinate scope after movement；
After movement according to the described GIS map after loading through latitude information and mobile rear hatch pixel coordinate scope,
The current window coordinate pixel of the current latitude and longitude information of each icon and each described icon, determines the map of each described icon
Mobile rear hatch pixel coordinate；
Map according to each described icon moves rear hatch pixel coordinate, by each icon described GIS map after movement
On shown.
Due to during moving to map, although the latitude and longitude information of map itself is unchanged, yet with shifting
During dynamic, latitude and longitude information can change in the pixel coordinate of current display screen, namely latitude and longitude information and window coordinates
Mapping relations between pixel there occurs change, thus leading to the window pixel coordinate of each icon to change.
Therefore, the longitude and latitude letter of the latitude and longitude information to GIS map, icon can in map moving process, be not related to
The change of breath, only need to determine the mapping relations between the latitude and longitude information of GIS map and window coordinates pixel after moving, you can
Determine that the map of each icon after map movement moves rear hatch pixel coordinate.In a specific example, original based on it
Mapping relations between latitude and longitude information and window coordinates pixel, the window coordinates pixel of each latitude and longitude information mapping is added institute
State map displacement, you can obtain the mapping relations between latitude and longitude information and window pixel coordinate after moving, and then i.e.
Can determine that the map of each icon moves rear hatch pixel coordinate.It will be appreciated by those skilled in the art that any possible side can be adopted
Formula executes said process, and here is not reinflated to be repeated.
Except the process to GIS map, can also be processed using icon as operation object, for example the contracting to icon
Put, to movement of icon etc..
Taking the processing procedure that icon is moved as a example, the method in the embodiment of the present invention can also include：
Receive icon move, described icon move includes icon mark, icon pixel displacement；
Identify the current latitude and longitude information, described of corresponding icon according to described icon pixel displacement, described icon
The latitude and longitude information of described GIS map after the current window pixel coordinate of the icon corresponding icon of mark, loading and loading
The window pixel coordinate range of described GIS map afterwards, believes through latitude after the movement determining the described icon corresponding icon of mark
Breath, described icon identify the mobile rear hatch pixel coordinate of corresponding icon；
Identify the mobile rear hatch pixel coordinate of corresponding icon according to described icon, by the described image mark after movement
Described GIS map after loading for the corresponding icon is shown, and updates the longitude and latitude that described image identifies corresponding icon
Information.
Because the window pixel coordinate range of the latitude and longitude information of GIS map, GIS map is fixed, may thereby determine that out
Mapping relations between each window pixel coordinate and latitude and longitude information on display screen, identify working as of corresponding icon in conjunction with icon
Front latitude and longitude information is it may be determined that go out the current window pixel coordinate of this icon.By above-mentioned icon move by icon
After moving icon pixel displacement, the new current window pixel coordinate of this icon after being moved is (i.e. above-mentioned
The mobile rear hatch pixel coordinate of icon).It is then based on relation between each window pixel coordinate and latitude and longitude information, icon
Mobile rear hatch pixel coordinate is it may be determined that the new latitude and longitude information going out pixel (is believed through latitude after the movement of above-mentioned icon
Breath), realize the movement to icon.The determination mode of specific mapping relations between window pixel coordinate and latitude and longitude information,
Can be to be carried out using any mode that is existing at present and being likely to occur later, here no longer repeats in detail.
Taking the processing procedure that icon is zoomed in and out as a example, the method in the embodiment of the present invention can also include：
Receive icon scaling instruction, described icon scaling instruction includes icon mark, icon scaling；
Obtain the current window pixel coordinate identifying corresponding icon with described icon, true according to described icon scaling
Reduced put after described icon identify the scaling rear hatch pixel coordinate of corresponding icon；
Identify the scaling rear hatch pixel coordinate of corresponding icon according to described icon, by the described icon mark after scaling
Corresponding icon is shown in described current GIS map.
Due to when zooming in and out, being not related to the change of the geographical location information to icon to icon, therefore, it can no
The latitude and longitude information (i.e. the latitude and longitude information of holding icon is constant) of icon need to be changed, only the window pixel coordinate of icon need to be entered
Row changes.When zooming in and out to icon, the change of window pixel coordinate is related to the window pixel coordinate of this icon
Coordinate range, i.e. the length of this icon and/or height.Specifically can be according to described icon scaling determines after scaling
Icon identifies the scaling rear hatch pixel coordinate of corresponding icon it is generally the case that due to the latitude and longitude information of GIS map, GIS
The window pixel coordinate range of map is fixed, may thereby determine that out each window pixel coordinate and latitude and longitude information on display screen
Between mapping relations.Identify the latitude and longitude information of corresponding icon in conjunction with icon it may be determined that going out the current window of this icon
The datum mark of pixel coordinate, a point of the current window pixel coordinate scope of this datum mark typically this icon, this point
Directly overlap with a pixel of the latitude and longitude information mapping being determined based on above-mentioned mapping relations with icon, this point can be
Some boundary point of icon or by icon current window pixel coordinate determine coordinate range in any one
Point.Then, you can determine that icon identifies the scaling rear hatch of corresponding icon with reference to said reference point, described icon scaling
Pixel coordinate, specific scalable manner can be identical with existing at present any scalable manner, and here is not reinflated to be repeated.Can
To be understood by, in the above-mentioned processing procedure to map scaling, the scaling process for icon can be with the phase in this example
With.
Based on the explanation of each specific example as above, it is clear that, in the scheme of the present embodiment, for icon
For, when this icon is preserved or applied, what this icon carried is latitude and longitude information, and icon is not directly and GIS
Map associates, the different maps for separate sources it is also possible to latitude and longitude information based on icon by this icon in different GIS
Shown on map and processed, realized display and the processing procedure of the multi-source map of icon.
It can be seen that, GIS map in embodiment of the present invention scheme, mainly in order to provide background tile, provide coordinate mapping, carry
For display control operation, and mouse, keyboard are provided, draw Action Events.During icon is shown, and it is not related to
Heart Background (i.e. GIS map), icon is to provide longitude and latitude per se with latitude and longitude information, an important function of GIS map
Mapping relations between information and window pixel coordinate.Thus, when being shown to icon and processing, with specific GIS ground
Figure is unrelated, only need to know how relation GIS map provides such mapping relations, and based on this mapping relations by the longitude and latitude of icon
Degree information MAP is corresponding window pixel coordinate, you can with reference to the window pixel coordinate of the latitude and longitude information of icon, icon, real
Existing display on map for the icon.
Accordingly, embodiment of the present invention scheme, can spreading out the map GIS, drawing ground when carrying out concrete application and realizing
The function modeling such as figure, coordinate mapping, display control, Action Events become interface class, that is, take out an intermediate layer to variant class
The map operation power function of type map is packaged.For example, it is assumed that there being two kinds of GIS map, they have the work(spread out the map
Can, but power function one cry Open, one be Load, then, in embodiment of the present invention scheme, can be unified encapsulation
Become a LoadMap (it is understood that will can do other different names after encapsulation), specific packaged type can be adopted
Carried out with any possible mode, the embodiment of the present invention is not specifically limited.Embodiment of the present invention scheme is being realized being directed to icon
The use of multi-source map when, can only need to know LoadMap, be Open or Load without care.Thus, by adopting
With the thought of object-oriented polymorphicization, different figure sources can be entered with the realization of line interface, then distinguish figure source by file suffixes
Type.
In a concrete application example, can be so that the GIS having realized encapsulation dynamic base to be placed on fixation in the form of plug-in unit
Catalogue carry out dynamic load, registration GIS typonym, instantiation function, the association information such as suffix during loading, thus real accordingly
Existing dynamic creation and dynamic destruction.
Taking a concrete application example as a example, embodiment of the present invention scheme (such as embodiment of the present invention when execution starts
When the corresponding software program of scheme starts, understand all dynamic base under this fixing catalogue of dynamic load, such as program place mesh
All of dynamic base in entitled XGIS file under record, and execute its RegisterGIS derivation function.Then some type
GIS map can provide entitled RegisterGIS to derive function, and this derivation function comes into CGISRegister class object example (to be had
One RegisterGISMap function).RegisterGIS derive function call CGISRegister RegisterGISMap to
An item data is added in dynamic registration list, comprises GIS typonym, instantiation function, association suffix.
When selecting a map file, obtain the file suffixes name of map file, find log-on message from register list,
Instantiated by instantiation function, recall opening function and spread out the map file.When spreading out the map file, can pass through
The GIS interface class of the above-mentioned encapsulation referring to is opened and is loaded the corresponding GIS map of ground map logo with described map to be opened.
When closing map window, can be destroyed with the empty destructor function of invocation map example.
It will be appreciated by persons skilled in the art that the difference based on the programming language being adopted, can also adopt
Other program words mention the method that function call mode is realized in above-described embodiment, and here no longer exhaustion repeats.
