Marker

The Marker component places a custom image at a geographic coordinate on the map. Must be rendered as a child of <Map>.

Import​

import { Marker } from 'react-native-here-explore';
import type { MarkerProps } from 'react-native-here-explore';

Usage​

Basic marker​

<Map
mapScheme="NORMAL_DAY"
zoomValue={14}
geoCoordinates={{ latitude: 48.8566, longitude: 2.3522 }}
>
<Marker
geoCoordinates={{ latitude: 48.8566, longitude: 2.3522 }}
image={require('./assets/pin.png')}
/>
</Map>

Remote image​

<Marker
geoCoordinates={{ latitude: 48.8566, longitude: 2.3522 }}
image={{ uri: 'https://example.com/marker.png' }}
/>

Scaled marker​

<Marker
geoCoordinates={{ latitude: 48.8566, longitude: 2.3522 }}
image={require('./assets/pin.png')}
scale={1.5}
/>

Custom size and anchor​

<Marker
geoCoordinates={{ latitude: 48.8566, longitude: 2.3522 }}
image={require('./assets/pin.png')}
size={{ width: 40, height: 56 }}
anchor={{ horizontal: 0.5, vertical: 1.0 }}
/>

Props​

PropTypeRequiredDefaultDescription
geoCoordinatesGeoCoordinatesYes—Position of the marker on the map
imageImageURISourceYes—Marker image. Accepts require() for local assets or { uri: '...' } for remote URLs
scalenumberNo—Scale multiplier. > 1 enlarges, < 1 shrinks
size{ width: number; height: number }No—Explicitly override the rendered image dimensions in pixels
anchor{ horizontal?: number; vertical?: number }No—Anchor point relative to the image (0–1). { horizontal: 0.5, vertical: 0.5 } = center

Anchor Point​

The anchor determines which part of the image aligns with the geoCoordinates on the map.

AnchorMeaning
{ horizontal: 0, vertical: 0 }Top-left corner
{ horizontal: 0.5, vertical: 0.5 }Center of image (default behavior)
{ horizontal: 0.5, vertical: 1.0 }Bottom-center (typical for pin icons)
{ horizontal: 1, vertical: 1 }Bottom-right corner

For a typical pin icon that points to the ground, use { horizontal: 0.5, vertical: 1.0 }.

See the HERE documentation on anchored markers for more detail.


Notes​

  • If the image cannot be resolved (e.g. the asset doesn't exist), the marker renders nothing.
  • scale and size are independent — size overrides the image dimensions directly, while scale multiplies them.
