Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
As shown in Figure 1, the present invention provides a kind of universal display method of indoor map, comprising the following steps:
Step 1, the point diagram layer data, line chart layer data, face figure layer number of pbf format are generated respectively according to original house data
It is stored in the form of key-value pair according to the attribute of, the point diagram layer data, line chart layer data, face figure layer data, and is single with floor
Member is organized, and all floor datas of a multi-story structure are as a house data unit, a corresponding data
File, as shown in Figure 2.
Figure layer is the set of a kind of map element with like attribute,
The describing mode of map element attribute, i.e. attribute-name=attribute value describe an attribute, such as code=in pairs
100001, the attribute of an entitled code, attribute value 100001.
Pbf:protocol buffer is a kind of structural data storage format being simple and efficient, and supports extension, across flat
Platform.This format is well suited for encoding for vector data, guarantees the versatility of data application.
Point diagram layer data, line chart layer data, face figure layer data and its attribute data is stored in server-side.
Step 2, opening relationships database establishes the house data list according to house data unit ID and tile number
The incidence relation of member and 16 grades of tiles.
Tile level and scale bar level be it is corresponding, the vector tile of the bigger division of tile level is more, and data are more smart
Carefully.16 grades of tile levels are equivalent to the 100m of map scale, and a vector tile range is exactly whole 1/2^16, for room
For this scene of interior map, the occupied area of a general building is not too large, most of all in 16 grades of tile models
In enclosing, even if tile quantity will not be excessive across multiple tiles, therefore some is described with 16 grades of vector tile range
The position of building is proper.
Here the method for opening relationships is using relational database, and the reason of opening relationships is easy for query vector tile packet
The data contained, and viewport range can also be relatively easy to and be converted to vector tile range, can simply judge so at present
Viewport range needs data to be shown.

Step 3, as shown in figure 3, carrying out configuration in client configures Show Styles using json formatted file, forward sight will be worked as
Mouth range is converted to 16 grades of tile ranges, and according to the incidence relation of figure layer data and 16 grades of tiles, inquiring current viewport range is needed
Data to be shown draw indoor map according to the Show Styles.
The basic format of Show Styles configuration file is as follows:
Main body is made of the array of figure layer " layers " in json.Each figure layer has an essential attribute " source-
Layer " is appointed as the title of data layer to be configured；Another attribute " type ", describes for distinguishing the figure layer
Point/line/face pattern；One optional attribute " filter " defines condition grammer, such as " filter ": [" code ", "==",
100002] indicate that the data element that code attribute value is 100002 in this data layer is drawn using this pattern.
The sequence of layers array specifies the sequence of data element drafting, to influence data element gland sequence.One
As gland sequence be all a gland line, line gland face adjusts the sequence of configuration style figure layer both adjustable gland sequences.
