geojson - Adding custom markers to the mapbox gl -

-

i add custom marker map. using mapbox gl script.

the documentation found related topic 1 https://www.mapbox.com/mapbox-gl-js/example/geojson-markers/.

i tried customize given example , managed add marker , modify little changing size, since don't understand parameters, don't know how add own marker. there documentation more detailed?

here code:

 <script>     mapboxgl.accesstoken = 'pk.eyj1ijoiywl3yxrrbyisimeioijjaxbncni5ejgwmde0dmjucta5adrrb2wzin0.b2zm8wb9m_qis1tneswslg';     var map = new mapboxgl.map({         container: 'map', // container id         style: 'mapbox://styles/aiwatko/cipo0wkip002ddfm1tp395va4', //stylesheet location         center: [7.449932,46.948856], // starting position         zoom: 14.3, // starting zoom         interactive: true     });             map.on('load', function () {     map.addsource("markers", {         "type": "geojson",         "data": {             "type": "featurecollection",             "features": [{                 "type": "feature",                 "geometry": {                     "type": "point",                     "coordinates": [7.4368330, 46.9516040]                 },                 "properties": {                     "title": "duotones",                     "marker-symbol": "marker",                  }             }]         }     });      map.addlayer({         "id": "markers",         "type": "symbol",         "source": "markers",         "layout": {             "icon-image": "{marker-symbol}-15",             "icon-size": 3         }     }); }); </script>

there 2 ways customize markers in mapbox.

raster markers in mapbox

see link on mapbox.com custom marker icons. example shows how use .png marker.

svg markers in mapbox

you pretty close modifying icons, take time familiarize parameters.

the icon-image may harder 1 understand. takes property "marker-symbol": "marker" geojson, , "icon-image": "{marker-symbol}-15", create final result of marker-15.

this brings further question: where/how markers defined?!?

the markers come mapbox , called maki icons. can change "marker-symbol" aquarium or cafe see results.

from mapbox gl style reference

  • icon-size — scale factor icon. 1 original size, 3 triples size.
  • icon-image — string {tokens} replaced, referencing data property pull from.
