Modes Plan 3D

Les modes de carte 3D suivants sont disponibles dans l'API Maps JavaScript :

  • ROADMAP affiche la carte routière par défaut avec les libellés de la carte de base.
  • SATELLITE affiche une carte photoréaliste basée sur des images aériennes.
  • HYBRID affiche la vue satellite avec les libellés de la carte de base.

Voici un exemple de carte 3D en mode ROADMAP :

TypeScript

async function init() {
  const { Map3DElement } = await google.maps.importLibrary('maps3d');

  const map = new Map3DElement({
    center: {
      lat: 37.79334535092104,
      lng: -122.400742086205,
      altitude: 0,
    },
    range: 2400,
    tilt: 65,
    heading: 0,
    mode: 'ROADMAP',
    internalUsageAttributionIds: ['gmp_git_jsapisamples_v1_3d-rendering'],
  });

  document.body.append(map);

  // Create the controls container
  const controls = document.createElement('div');
  controls.id = 'controls';
  controls.classList.add('map-mode-control');

  // Create the select element
  const selector = document.createElement('select');
  selector.id = 'map-mode';

  const modes = ['ROADMAP', 'SATELLITE', 'HYBRID'];
  modes.forEach((modeName) => {
    const option = document.createElement('option');
    option.value = modeName;
    option.textContent = modeName;
    if (modeName === 'ROADMAP') {
      option.selected = true;
    }
    selector.appendChild(option);
  });

  selector.addEventListener('change', (event) => {
    map.mode = (event.target as HTMLSelectElement).value;
  });

  controls.appendChild(selector);
  document.body.appendChild(controls);
}

init();

Principaux avantages

  • Globe : vous pouvez désormais offrir une expérience cartographique complète pour différents cas d'utilisation en exploitant des images de carte abstraites et photoréalistes.
  • Personnalisation : vous pouvez désormais basculer entre les modes à l'aide d'un bouton ou d'une fonction personnalisés sans recharger le composant global.
