Create a draggable Marker

Drag the marker to a new location on a map and populate its coordinates in a display.

Create a draggable point

Drag the point to a new location on a map and populate its coordinates in a display.

Use a fallback image

Use a coalesce expression to display another image when a requested image is not available.

Add a pattern to a polygon

Use fill-pattern to draw a polygon from a repeating image pattern.

Filter symbols by text input

Filter symbols by icon name by typing in a text input.

Filter symbols by toggling a list

Filter a set of symbols based on a property value in the data.

Filter within a Layer

Filter a layer based on user input using setFilter().

Fit a map to a bounding box

Fit the map to a specific area, regardless of the pixel size of the map.

Slowly fly to a location

Use flyTo with flyOptions to slowly zoom to a location.

Fly to a location

Use flyTo to smoothly interpolate between locations.

View a fullscreen map

Toggle between current view and fullscreen mode. Does not work on iPhones because a pseudo-fullscreen is used, and the code is embedded in an iframe, which prevents the map from scaling.

Navigate the map with game-like controls

Use the keyboard's arrow keys to move around the map with game-like controls.

Geocode with Nominatim

Geocode with Nominatim and the maplibre-gl-geocoder plugin.

Add a new layer below labels

Use the second argument of addLayer to add a layer below labels.

Add a GeoJSON line

Add a GeoJSON line to a map using addSource, then style it using addLayer’s paint properties.

Draw GeoJSON points

Draw points from a GeoJSON collection to a map.

Add a GeoJSON polygon

Style a polygon with the fill layer type.

Create a heatmap layer

Visualize earthquake frequency by location using a heatmap layer.

Disable interactivity to create a static map.

Jump to a series of locations

Use the jumpTo function to showcase multiple locations.

Change a map's language

Use setLayoutProperty to switch languages dynamically.

Display line that crosses 180th meridian

Draw a line across the 180th meridian using a GeoJSON source.

Create a gradient line using an expression

Use the line-gradient paint property and an expression to visualize distance from the starting point of a line.

View local GeoJSON

View local GeoJSON without server upload.

Use locally generated ideographs

Set localIdeographFontFamily to override the font used for displaying CJK (Chinese, Japanese and Korean) characters, ignoring the map style. This setting must be a CSS font rule specifying fallbacks of on-device fonts. Set localIdeographFontFamily to false to use server-provided fonts, which is much slower.
