Can also for example, monitoring user mouse action, when user by mouse carry out slide in current map when,
According to the range that user's mouse slides, map location data to be drawn are determined.It is using current map as base with the map drawn
Level is set, the data drawn again being extended on current map.
It can also be for example, the mouse action of user be monitored, when user is zoomed in or out in current map by mouse
When operation, according to the instruction that user's mouse zooms in or out, map location data to be drawn are determined.With draw map be with
Current map is benchmark position, the data drawn again being extended on current map.
It in S204, is determined according to the map location data and draws container data, the drafting container data includes arrow
Measure tile and multiple figure layers.It wherein, will be in advance in html file when JavaScript API relevant using map
The label of one div of middle creation, then all mappings work can all carry out in this label, this label is temporarily known as
Map cases.Wherein, api function, operating system other than the execution of coordinate application, Memory Allocation, system resource management,
It is also simultaneously a very big service centre, calls the various services (each service is a function) of this service centre,
Application program can be helped to achieve the purpose that unlatching form, generating writing pattern, using peripheral equipment, due to pair of these function services
It likes application program (Application), so referred to as Application Programming Interface, abbreviation API
Function.
In one embodiment, drawing container data includes vector tile and multiple figure layers, and map vector tile is a kind of
Novel mode.Map datum can be transmitted in map vector tile with the formats piecemeal such as json, in browser end benefit
Map is being shown with front end frame.The volume of transmitted data of vector tile is few, and server stress is small, and rendering is facilitated to become each
The map of kind various kinds.
In one embodiment, the figure layer that vector tile is named by one group is constituted.Each figure layer include geometric element and
Metadata information.The figure layer format of design can guarantee that figure layer data can be arranged in order in memory, thus in figure layer group
It adds a new figure layer and does not just have to change existing data in end.
The figure layer of vector tile has the feature that every block of vector tile should contain at least one figure layer, each figure layer
Element should be contained at least one.
Figure layer must be comprising a version field as major version number, and figure layer must include a name field.Figure layer
In each element may include one or more key-value as its metadata.Key the and value quilt of all elements
Index is two lists: keys and values respectively, shared by all elements in figure layer.
Each element of figure layer keys field is character string.Each element of figure layer values field is a plurality of types of
The coding of value.Values field contains the value of all elements in figure layer, and each value can by it
Call number reference in values list, the call number of first value is 0.
Figure layer must include an extent field, indicate the width and height of tile, in round figures.In vector tile
The range that can define beyond extent of geometric coordinate.Geometric element beyond extent range is frequently used to as buffering
Area, to render the element overlapped in muti-piece adjacent tiles.
In S206, the multiple figure layer is traversed according to the permissions data and extracts symbolic coding.Wherein, in vector tile
Geometric data be defined as screen coordinate system.The upper left corner (display default is such) of tile is the origin of coordinate system.X axis is right
It is positive, is positive under Y-axis.Coordinate in geometric figure is necessary for integer.
Geometric figure is stored in the figure layer of vector tile, and geometric figure is encoded as the one of the field of element
A 32 without character type integer sequence.Decoder parses these integer sequences as a series of orderly behaviour for generating geometric figure
Make.
In one embodiment, the multiple figure layer extraction symbolic coding is traversed according to the permissions data to comprise determining that
The corresponding multiple vector element libraries of the multiple figure layer；Multiple vector element libraries extraction vectors are traversed according to the permissions data to want
Element；And the symbolic coding is determined in symbol configuration according to the vector element.It specifically can be for example, being directed to different use
Different operating rights is arranged in family, and the symbolic coding that different users can obtain is distinguished.
In one embodiment, traversing multiple vector element libraries to extract vector element according to the permissions data includes: time
The multiple vector element library is gone through to obtain multiple candidate vectors elements；According to the permissions data to the multiple candidate vectors
Element carries out rejecting processing, generates vector element.
In one embodiment, can such as party A-subscriber permission with higher, party A-subscriber in the map for checking B location (exhibition
Show that B location map needs to load multiple vector tiles) 100 symbolic codings can be obtained.100 symbolic codings can represent different
Figure and Image can may be, for example, elevation information for example, show the various details in the map after later rendering,
The information such as regional weather information, traffic information and venue.
In one embodiment, for example party B-subscriber there can be lower permission, party B-subscriber can obtain in the map for checking B location
Take 80 symbolic codings.80 symbolic codings can represent different Figure and Images, can be for example, display should after later rendering
Various details in map may be, for example, the information such as elevation information, venue.
In one embodiment, can also be drawn a portrait according to different users is the different permission of user setting, can for example for
Label is the female user of " makeups ", shows the dress ornament class mall information near its searching position emphatically, and is " beauty for label
The user of food ", shows emphatically the food and drink relevant information etc. near its searching position, can be according to the grade of user or feature etc.
The different permission of various feature-sets, to carry out personalized displaying in map scene, setting the application about permission is not
As limit.
In S208, the symbolic coding render and show on the vector tile to generate the arrow
Quantity map.The symbolic coding is carried out to render and carry out on the vector tile in the browser constructed based on html5
Display is to generate the map vector.Standard of the html5 as next generation html assigns the better meaning of webpage and structure.Base
Possess shorter starting time and faster networking speeds in the application of html5, offline Web can be supported to apply.
In one embodiment, the symbolic coding a variety of browsers are based on to render；And by the institute after rendering
It states symbolic coding and generates map vector；A variety of browsers include: IE browser and/or Safari browser and/or
Chrome browser.
In one embodiment, the symbolic coding is subjected to rendering and is shown on the vector tile to generate
The map vector includes: to render the symbolic coding to generate multiple pels；And pass through unified Image Rendering
The multiple pel is plotted in the vector tile to generate the map vector by interface.
In one embodiment, the symbolic coding is rendered to generate multiple pels includes: to compile the symbol
Code rendered according to its corresponding map vector；And multiple figures are generated by the symbolic coding after rendering
Member.
Fig. 3 is a kind of schematic diagram of the map vector generation method shown according to another exemplary embodiment.Fig. 3 is shown
A kind of display state of map vector, the map vector generation method of the disclosure carry out the vector data based on browser visual
Change and show, realizes its prototype system.National maps are drawn out, and mark main cities.In map vector, can increase with
The interaction of label is drawn, label can be moved with map.
According to the map vector generation method of the disclosure, is determined according to the map location data and draw container data, root
The multiple figure layer, which is traversed, according to the permissions data extracts symbolic coding；And then the symbolic coding render and described
