Can be more difficult to change a marker image after it is associated with a marker object.

Can be more complex to implement than default marker methods that add markers on top of a map.

Symbol layers can be used in combined marker methods.

In mobile development, reduces the need to synchronize multiple views.

Markers are exposed to Mapbox APIs, enabling user interactions.

Easier to style markers consistently across platforms.

Detailed styling options are available for markers inside symbol layers.

Highly performant recommended for maps with over 100 markers.

In mobile development, this is sometimes called the sources and layers method. In web development, this approach is called the canvas method because it draws markers on the HTML canvas element. The first approach is to add markers inside a map, where they exist in a symbol layer.

Adding markers on top of a map, which offers styling advantages.Ĭontinue reading to understand the two approaches, so you can reflect on the needs of your application and choose a marker method that best fits your project needs.

Adding markers inside a map, which offers performance advantages.

There are two main approaches for this task: Now that you've learned about marker images and source data, you are ready to combine the two to add a marker to your map. This data includes nine point features representing the locations of parks in Chicago, Illinois.

If you want some sample point data, you can download the GeoJSON data from our Add points to a web map tutorial, or link to the public Mapbox-hosted vector tileset by using its ID: examples.civir98a801cq2oo6w6mk1aor-9msik. Continue to the add markers section to choose a method for adding your markers. The specific method you choose to add markers to your map will determine the workflow required to add your data source. You can add data from a vector tileset to a map at runtime by providing a link to the tileset, which can be hosted on Mapbox, referenced within in a Mapbox style, or hosted externally. You can add GeoJSON data to a map at runtime by hard-coding the data inline or linking to an API endpoint that serves data as GeoJSON. You can add data to a map style before runtime by using the Mapbox Studio style editor to add a vector tileset as a source for a layer in a map style. To add multiple markers, or to add markers to interactive web or mobile maps, you generally must provide point data in GeoJSON format or in a vector tileset. Learn more in the Static Images API marker method section, below. If you are adding a single marker to a static, non-interactive map image, you can provide your point data as a single pair of coordinates in your API request. These tools can help you get latitude and longitude coordinates.

You can also use free tools like geojson.io or QGIS to draw points on a map, then export your data as GeoJSON.

You can create a dataset with the Mapbox Studio dataset editor. You can learn more about default marker methods in marker methods, below. In the table below, you can see the default marker images for Mapbox GL JS and the Static Images API and the default marker methods used to create them. Each also allows you to add and use a custom image instead of the default marker image. symbol layer: in Mapbox, a layer that renders icons or text on a mapĮach Mapbox SDK and API provides a default marker image that is used by its default Marker method.source: in Mapbox, any data referenced by a map style layer.point: a geospatial feature defined by one pair of coordinates.Marker: in Mapbox GL JS, the default Marker method and the object it creates.marker: an image on a map, representing a location.icon: in Mapbox, the visual part of a marker.DOM: an object representing the structure and content of a web document.custom image: in Mapbox, an image imported by a user.canvas: in web development, an HTML element used to draw graphics.annotation: in mobile development, a shape or icon added to a map.The capitalized word Marker is reserved for default marker methods of that name, and the corresponding objects they create.įor more detailed definitions, click the terms below or visit the Glossary. In Mapbox, a marker is a visual representation of a specific coordinate or point feature on a map. It can be helpful to understand key terms related to markers.
