HTML Google Maps
HTML Google Map is used to display maps on your webpage. You can simply add a map on your basic HTML page.
Syntax:


<!DOCTYPE html>

<html>

<body>

<h1>First Google Map Example</h1>

<div id="map">My map will go here...</div>

</body>

</html>


Set the Map Size
You can set the map size by using the following syntax:


<div id="map" style="width:400px;height:400px;background:grey"></div>


How to create a function to set the map properties?
You can set the map properties by creating a function. Here, the function is myMap(). This example shows the Google map centered in London, England.
We have to use the functionalities of Google Maps API provided by a JavaScript library located at Google. Use the following script to refer to the Google Maps API with a callback to the myMap function.


<script src="https://maps.googleapis.com/maps/api/js?callback=myMap"></script> 


Example:


<!DOCTYPE html>

<html>

<body>

<h1>My First Google Map</h1>

<div id="map" style="width:400px;height:400px;background:grey"></div>

<script>

function myMap() {

var mapOptions = {

    center: new google.maps.LatLng(51.5, -0.12),

    zoom: 10,

    mapTypeId: google.maps.MapTypeId.HYBRID

}

var map = new google.maps.Map(document.getElementById("map"), mapOptions);

}

</script>

<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyBu-916DdpKAjTmJNIgngS6HL_kDIKU0aU&callback=myMap"></script>

</body>

</html>



Example Explanation
mapOptions: It is a variable which defines the properties for the map.
center: It specifies where to center the map (using latitude and longitude coordinates).
zoom: It specifies the zoom level for the map (try to experiment with the zoom level).
mapTypeId: It specifies the map type to display. The following map types are supported: ROADMAP, SATELLITE, HYBRID, and TERRAIN.
var map=new google.maps.Map(document.getElementById("map"), mapOptions): It creates a new map inside the  element with id="map", using the parameters that are passed (mapOptions). 

HTML Multiple Maps
You can use different map types in a single example.
Example:


<!DOCTYPE html>

<html>

<body>

<div id="googleMap1" style="width:400px;height:300px;"></div>

<br>

<div id="googleMap2" style="width:400px;height:300px;"></div>

<br>

<div id="googleMap3" style="width:400px;height:300px;"></div>

<br>

<div id="googleMap4" style="width:400px;height:300px;"></div>

<script>

function myMap() {

  var mapOptions1 = {

    center: new google.maps.LatLng(51.508742,-0.120850),

    zoom:9,

    mapTypeId: google.maps.MapTypeId.ROADMAP

  };

  var mapOptions2 = {

    center: new google.maps.LatLng(51.508742,-0.120850),

    zoom:9,

    mapTypeId: google.maps.MapTypeId.SATELLITE

  };

  var mapOptions3 = {

    center: new google.maps.LatLng(51.508742,-0.120850),

    zoom:9,

    mapTypeId: google.maps.MapTypeId.HYBRID

  };

  var mapOptions4 = {

    center: new google.maps.LatLng(51.508742,-0.120850),

    zoom:9,

    mapTypeId: google.maps.MapTypeId.TERRAIN

  };

  var map1 = new google.maps.Map(document.getElementById("googleMap1"),mapOptions1);

  var map2 = new google.maps.Map(document.getElementById("googleMap2"),mapOptions2);

  var map3 = new google.maps.Map(document.getElementById("googleMap3"),mapOptions3);

  var map4 = new google.maps.Map(document.getElementById("googleMap4"),mapOptions4);

}
