Google Maps is a web mapping service that is free by Google. This service provides various types of geographical information. With the help of google map, searching places and direction can be done. Also, we can get the traffic information of a specific area or view street-level images of cities.
Google Maps has a JavaScript API. This API is used to customize the map which displays the information.
Example:
<!DOCTYPE html> <html> <head> <title>
Google Maps | Introduction
</title>
<!-- Add Google map API source -->
<script src=
</script>
<script>
function GFG() {
var CustomOp = {
center: new google.maps.LatLng(
28.502212, 77.405603),
zoom: 17,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
// Map object
var map = new google.maps.Map(
document.getElementById("DivID"),
CustomOp
);
}
</script>
</head> <!-- Function that execute when page load --> <body onload="GFG()">
<center>
<h1 style="color:green">

<h3>Google Maps</h3>
<!-- Basic Container -->
<div id="DivID" style="width:400px; height:300px;">
</div>
</center>
</body> </html> |
Output:
Exaplaination:
- In the above example, we will use Google API to load google map.
<script src = "https://maps.googleapis.com/maps/api/js"></script>
Following are the steps required to get an API key:
-
Go to the below-mentioned link
https://console.developers.google.com/flows/enableapi?apiid=maps_backend,geocoding_backend,directions_backend,distance_matrix_backend,elevation_backend,places_backend&reusekey=true - Create a new project or select from your existing projects.
- Click Continue to enable the API.
- On the Credentials page, get an API key (and set the API key restrictions).
- Replace the value of the key parameter in the URL with your own API key
-
Go to the below-mentioned link
- To customize the maps:
var CustomOp = { center:new google.maps.LatLng(28.502212, 77.405603), zoom:17, mapTypeId:google.maps.MapTypeId.ROADMAP };In this case, CustomOp is an object that contains 3 options, centre, zoom, and maptypeid.
- centre: This property is used to set the specific point in maps.
- zoom: This property is used to specify the zoom level on a specific point.
- maptypeid: This property is used to specify the type of map. (ROADMAP, SATELLITE, HYBRID, TERRAIN)
-
To create a map object we will use the following code:
var map = new google.maps.Map(document.getElementById("DivID"), CustomOp);
