This example creates a map showing satellite imagery tilted at 45 degrees, along
with a button that will rotate the map periodically.
TypeScript
let map: google.maps.Map;
function initMap(): void {
map = new google.maps.Map(document.getElementById("map") as HTMLElement, {
center: { lat: 40.76, lng: -73.983 },
zoom: 15,
mapTypeId: "satellite",
heading: 90,
tilt: 45,
});
// add listener to button
document.getElementById("rotate")!.addEventListener("click", autoRotate);
}
function rotate90(): void {
const heading = map.getHeading() || 0;
map.setHeading(heading + 90);
}
function autoRotate(): void {
// Determine if we're showing aerial imagery.
if (map.getTilt() !== 0) {
window.setInterval(rotate90, 3000);
}
}
declare global {
interface Window {
initMap: () => void;
}
}
window.initMap = initMap;
JavaScript
let map;
function initMap() {
map = new google.maps.Map(document.getElementById("map"), {
center: { lat: 40.76, lng: -73.983 },
zoom: 15,
mapTypeId: "satellite",
heading: 90,
tilt: 45,
});
// add listener to button
document.getElementById("rotate").addEventListener("click", autoRotate);
}
function rotate90() {
const heading = map.getHeading() || 0;
map.setHeading(heading + 90);
}
function autoRotate() {
// Determine if we're showing aerial imagery.
if (map.getTilt() !== 0) {
window.setInterval(rotate90, 3000);
}
}
window.initMap = initMap;
