GeoStyler-Style-Parser implementation for Mapbox
Important Notes
Since mapbox works with spritesheets, geostyler-mapbox-parser is only capable of handling sprites/icons if the application that is using the parser implements following API:
GET /sprites/?name&baseurl
name
- name of the sprite in the spritesheet corresponding jsonbaseurl
- baseurl for retrieving spritesheet and sprite json
The endpoint MUST return a reference to a single image.
Mapbox styles require the properties sources
(root property)
and source
(layers property).
In order to keep a clear separation between style and data, geostyler-mapbox-parser puts the source-related attributes into the metadata block of
a geostyler-style under mapbox:ref
. There, the original sources object, as well as the mappings between layers and sources will be stored
(properties sources
, sourceMapping
and layerSourceMapping
). Applications can then use these mappings for re-creating the same layer structure
using their map library of choice (e.g. OpenLayers, etc.).
How to use
ES6:
import MapboxParser from "geostyler-mapbox-parser";
const pointSimplePoint = {
name: "My Style",
rules: [
{
name: "My Rule",
symbolizers: [
{
kind: "Mark",
wellKnownName: "circle",
color: "#FF0000",
radius: 6
}
]
}
]
};
const parser = new MapboxParser();
const { output: mbStyle } = await parser.writeStyle(pointSimplePoint);
console.log(mbStyle);
Browser:
const pointSimplePoint = {
name: "My Style",
rules: [
{
name: "My Rule",
symbolizers: [
{
kind: "Mark",
wellKnownName: "Circle",
color: "#FF0000",
radius: 6
}
]
}
]
};
var parser = new GeoStylerMapboxParser.MapboxStyleParser();
parser
.writeStyle(pointSimplePoint)
.then(function(res) {
var mbStyle = res.output;
console.log(mbStyle);
});
