在矢量地图上,您可以设置标记以什么样的海拔高度显示。这样做有助于在 3D 地图内容中正确显示标记。如要为标记设置海拔高度,请指定 LatLngAltitude 作为 MarkerView.position 选项的值:
TypeScript
constpin=newPinElement({background:'#4b2e83',borderColor:'#b7a57a',glyphColor:'#b7a57a',scale:2.0,});constmarkerView=newAdvancedMarkerElement({map,content:pin.element,// Set altitude to 20 meters above the ground.position:{lat:47.65170843460547,lng:-122.30754,altitude:20}asgoogle.maps.LatLngAltitudeLiteral,});

map.addListener('zoom_changed',()=>{constzoom=map.getZoom();if(zoom){// Only show each marker above a certain zoom level.marker01.map=zoom > 14?map:null;marker02.map=zoom > 15?map:null;marker03.map=zoom > 16?map:null;marker04.map=zoom > 17?map:null;}});

Collision behavior is only supported on vector maps.\n\nTo set collision behavior, set `AdvancedMarkerElement.collisionBehavior` to one of\nthe following:\n\n- `REQUIRED`: (default) Always display the marker regardless of collision.\n- `OPTIONAL_AND_HIDES_LOWER_PRIORITY` Display the marker only if it does not overlap with other markers. If two markers of this type would overlap, the one with the higher `zIndex` is shown. If they have the same `zIndex`, the one with the lower vertical screen position is shown.\n- `REQUIRED_AND_HIDES_OPTIONAL` Always display the marker regardless of collision, and hide any `OPTIONAL_AND_HIDES_LOWER_PRIORITY` markers or labels that would overlap with the marker.\n\n| **Note:** On raster maps, only marker-to-marker collisions are detected. Marker collisions with basemap labels are supported only on vector maps.\n\nThe following example shows setting collision behavior for a marker:\n\n\nTypeScript \n\n```typescript\nconst advancedMarker = new AdvancedMarkerElement({\n position: new google.maps.LatLng({ lat, lng }),\n map,\n collisionBehavior: collisionBehavior,\n});https://github.com/googlemaps-samples/js-api-samples/blob/5f4e6decfaf59cd69918bbf4e6338de03a63a5ba/dist/samples/advanced-markers-collision/docs/index.ts#L64-L68\n```\n| **Note:** Read the [guide](/maps/documentation/javascript/using-typescript) on using TypeScript and Google Maps.\n\nJavaScript \n\n```javascript\nconst advancedMarker = new AdvancedMarkerElement({\n position: new google.maps.LatLng({ lat, lng }),\n map,\n collisionBehavior: collisionBehavior,\n});https://github.com/googlemaps-samples/js-api-samples/blob/5f4e6decfaf59cd69918bbf4e6338de03a63a5ba/dist/samples/advanced-markers-collision/docs/index.js#L49-L53\n```\n\n\u003cbr /\u003e\n\nSet marker altitude\n\n\nOn vector maps, you can set the altitude at which a marker appears. This is\nuseful for making markers appear correctly in relation to 3D map content.
