The mapping relations of the second map datum parameter in table refer to table 1.
The mapping table of the map datum parameter of table 1 first and the second map datum parameter
The second map datum in the above-mentioned allocation list on the first map datum parameter and static readonly map system end
The table of the mapping relations of parameter only illustrates a part, should be specifically defined by actual conditions.
Alternatively, before static readonly map file is generated, in addition to：
The map datum in map styles file is carried out according to the loading rule at default static readonly map system end
Processing；Wherein, the static readonly map system end loading rule includes the scope and list of static readonly map datum property value
Position.
Specifically, because the map datum value in map styles file is according to mapping system end rule
(mapboxgl specifications) storage, and mapping system end is regular with static readonly map system end loading rule (mapnik
Specification) disunity, accordingly, it would be desirable to according to the conversion of static readonly map system end loading rule and mapping system end rule
Relation handles the map datum value of map styles file successively, for example, a width of 0.2 pound of map styles file center line.Map styles
The form of file is generally extensible markup language form (XML format), and the present invention does not do any limitation to this.
Alternatively, when performing step S120, the processing request that the basis is received, based on map styles file
In map datum, and the first map datum parameter in the allocation list of default mapping system end with static readonlyly

File.
Specifically, map datum value is typically stored in map styles file with data mode, its data type typically with
First map datum parameter is consistent.The data type of the map datum value in map styles file is determined successively, and Ergodic Maps are closed
It is table (reference table 1), the first map datum parameter for being matched with data type is determined in mapping table, according to above-mentioned the
The corresponding second map datum parameter of one map datum parameter, is read out to corresponding map datum value, generates static readonly
Map file.
For example, by the filter (filter) of layer style (layer) object in map styles file, minimum display level
And the value of maximum display level (maxzoom) reads rule (Rule) object in static readonly map file (minzoom)
Filter (filter), minimum scale chi denominator (MinScaleDenominator) and maximum ratio chi denominator
(MaxScaleDenominator) in.
In one embodiment, due to there is no source of map data and the response mechanism of map layer in mapnik specifications,
When generating static readonly map file, pass through map datum value in parameter (Parameters) storage of array map styles file
(source) with the corresponding relation of map datum figure layer (source-layer), e.g., Parameters:[
{parameter:{source:{hyda:’http://******’,resa:’http://******’}}}
]
Based on the particularity of some data values in map styles file, when generating static readonly map file, carry out
Specially treated.Such as, the corresponding type (type) of layer style (Layers) in map styles file is equal to background
(background) relevant data value is read in the background in static readonly map file.By map styles file
Each type (type) value is not equal to background (background) relevant data value in middle layer style (Layers)
Read in the symbol (Symbolizer) in static readonly map file.
Preferably, value of the determination under the second map datum parameter, including：
It is determined that with whether there is mark attribute in the parameter attribute of the first map datum parameter of map data matching；

For example, mark is the explanation to shape content in map, explanation, mark has quite important make in drawing course
With, and mark and may conflict.In order to solve to mark collision problem, more preferable mapping effect is obtained, is avoided and calculated using mark
Method (such as Placement-type algorithms) successively reads the attribute of map datum value for the map datum value of mark attribute quiet
Corresponding position such as candidate's labeling position in the read-only map file of state.
In addition, there may be shield reference symbol number (ShieldSymbolizer) data in map styles file, this kind of data are
In map making with reference to the textual character (TextSymbolizer) and legend in the second map datum parameter
(MarkerSymbolizer) a kind of special symbol (Symbolizer), but according to mapboxgl the first map datum
Parameter can not be distinguished.Therefore, for the needs that chart, metadata (metadata) object in map styles file
One shield mark (shiled) array of middle addition, the style identifications of its figure layer including shield reference symbol number that is stored with pass through pattern
Mark determine by digital independent in shield arrays into the ShieldSymbolizer in static readonly map file still
TextSymbolizer and MarkerSymbolizer.
