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

Important note about maps credentials

Nokia provides several services options within the Maps API offering. The service is free to use, but you must obtain and use authentication and authorization credentials to use the services. Please read the Terms and Conditions and check the Pricing Plans page to decide which business model best fits your needs. Authentication requires unique Maps API credentials, namely an AppId and a token. You can get these credentials free for free following the instructions here


The API definition:

    new (path, props) 
nokia.maps.geo.Strip | nokia.maps.geo.Coordinate[]} path The path as coordinate strip.} props The initial values of the specified properties.

To draw the Polygon we will create a new geo.Strip with GeoCoordinates and then a new Polygon will be instantiated using it. The Properties are defined the same way for drawing a Circle, Polyline or a Polygon.

Example code

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script type="text/javascript"
src="" charset="utf-8">
<div id="mapContainer" style="z-index: -1; left:0px; top:0px; width: 100%; height: 80%; position: absolute;"></div>
<script type="text/javascript">
// Don't forget to set your API credentials
// Replace with your appId and token which you can obtain when you
// register on
nokia.Settings.set( "appId", "YOUR APP ID GOES HERE");
nokia.Settings.set( "authenticationToken", "YOUR AUTHENTICATION TOKEN GOES HERE");
myGeoStrip = new nokia.maps.geo.Strip([52,13,100,48,2,100,48,16,100,52,13,100], "values lat lng alt");
var map = new"mapContainer"), // new instance of Ovi Maps
components: [ new,
'zoomLevel': 4,
'center':[53.1, 13.1]
map.set("baseMapType", map.SATELLITE);
//new (path, props)
{nokia.maps.geo.Strip | nokia.maps.geo.Coordinate[]} path The path as coordinate strip.
{} props The initial values of the specified properties.
