return geo；}
Secondly, BUFF result and region in basic map that the spatial data of different types of data is corresponding are determined
The topology pass of the face data in figure layer (including provincial boundaries figure layer, circle of city figure layer, circle of county figure layer etc.) face, region, place
System's (including overlapping relation, from relation, inclusion relation).Wherein, during basic map is electronic chart
A part, the data in this basic map will not be updated, generally include administrative region, forest, water system,
Road and POI (Point of Interest, point of interest) etc..Face, region refers to necessary being in basic map
Region, locus, be typically made up of national boundaries, provincial boundaries, circle of city, Jie Deng boundary line, county, and basis ground
Figure belongs to fixed indices figure layer.
Again, determine that the BUFF that a certain spatial data is corresponding is contained in administrative division map layer location in basic map
During face, territory, then the basic business data that this spatial data is corresponding possess the attribute in this face, region, such as, a certain
Certain of certain province subordinate that the BUFF that spatial data is corresponding is contained in the figure layer of spatial fundamental region
City, then the authority of the basic business data that this spatial data is corresponding belongs to this city of this province subordinate；Determine certain
The BUFF that one spatial data is corresponding intersect with face, region, administrative division map layer place in basic map or from time, then
The basic business data that this spatial data is corresponding do not possess the attribute in this face, region.
Wherein, this spatial data can be obtained according to the authority ownership of the geographical location information of spatial data corresponding
Basic business data corresponding to the multiple attributes information of basic business data, such as certain spatial data belong to certain and save
Being an attribute information, the basic business data that this spatial data is corresponding particularly belong to certain certain saved city, again
It it is an attribute information.According to BUFF result and the comparison knot in face, region, administrative division map layer place in basic map
Really, the Regional Property information that available each basic business data are had.
Further, can determine that basic business data are at electronics according to the Regional Property information of basic business data
Visible level on map, i.e. basic business data are accessed for level authority information, in order to determine at electronics
Which level of map show these basic business data to present to user, particularly as follows:
For each basic business data, according to the Regional Property information of these basic business data, from electronically
The configuration file of figure obtains the visible level (electronics of this region belonging to basic business data in electronic chart
Visual level in the slice level of map), make visible level acquiescence and this basis of these basic business data
The visible level of the region belonging to business datum keeps consistent.The false code implemented is as follows:
Function setMapLayerLevelFilter(){
map.enableLayerLevelLocaltion(number level)；It is visible that // startup carries out level to figure layer
Range filter method, acquiescence starts consistent with basic map holding }；
Further, can determine that basic business data are at electronics according to the Regional Property information of basic business data
Map in map accesses region authority, particularly as follows:
For each basic business data, according to the Regional Property information of these basic business data, from electronically
The authority allocation list of figure obtains region allocation list information；And believe according to the Regional Property of these basic business data
These basic business data are hidden and show setting, i.e. if the visual range of current map does not wraps by breath
When including these basic business data, it is not loaded with this basic business data, on electronic chart, does not show this basis
Business datum, if the visual range of current map includes these basic business data, loads this basic business number
According to, and on electronic chart, show this basic business data.The false code implemented is as follows:
Function setMapLayerFilter(){
map.enableLayerLocaltion()；Figure layer is carried out based on location filtering method by // startup }
Concrete, the method for the above-mentioned Regional Property information determining each basic business data, according to basic business
The Regional Property information of data determine the basic business data visible level on electronic chart method and
Regional Property information according to basic business data determines that basic business data map in electronic chart is visited
Ask that the method for region authority is prior art, the most do not do too much explanation.
Concrete, outside the region belonging to certain basis business datum in the range of receive this basis industry of access
Business data request time, then refuse this access request, i.e. not in the region belonging to these basic business data
This basic business data are accessed in the range of outside.Such as certain basis business datum belongs to A and saves, then at B
Save and do not possess the authority accessing these basic business data.
