This article will introduce how to draw a circle on the Nokia Maps.


Nokia Maps API supported web browser (basically any modern web browser)

Important about Maps credentials

With Nokia Maps API you can start without having any credentials given, but you might face a performance gap. In order to get the full potential out of the offering, you must get the credentials that authenticate your application against the Services. Please read through the Location API.

For more information on how to obtain the credentials, please start with the Nokia Maps API Developers Guide section "Acquiring API credentials"


The API definition:

new nokia.maps.map.Circle (center, radius, props)

In the example below, we will create new circles with an increasing radius and add them all one by one to the map display in a loop.

Example code

<script type="text/javascript"
src="http://api.maps.nokia.com/2.0.0/jsl.js" charset="utf-8">
<div id="map" style="width:100%; height:80%;"></div>
<script type="text/javascript">
var map= new nokia.maps.map.Display(document.getElementById("map"), // new instance of
components: [ new nokia.maps.map.component.Behavior(),
new nokia.maps.map.component.ZoomBar(),
new nokia.maps.map.component.Overview(),
new nokia.maps.map.component.TypeSelector(),
new nokia.maps.map.component.ScaleBar()],
'zoomLevel': 4,
'center':[19.119, 72.8957]
function draw_Circle(loop){
map.objects.add(new nokia.maps.map.Circle(
// Place the circle center here
[19.15, 73.91],
// Radius of 8000 meters
color: "#829f",
fillColor: "#2387",
width: 100
