Prerequisites

HERE 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

Implementation

The API definition:

    new nokia.maps.map.Polygon (path, props) 
 
nokia.maps.geo.Strip | nokia.maps.geo.Coordinate[]} path The path as coordinate strip.
nokia.maps.map.Polygon.Properties} 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

NokiaMapsPolygon.png

function addPolygonToMap(map){
var geoStrip = new nokia.maps.geo.Strip
([52,13,100,48,2,100,48,16,100,52,13,100], "values lat lng alt");
map.objects.add(
new nokia.maps.map.Polygon(geoStrip, {
precision: 36,
simplify: 16,
fillColor: "FFFFCC",
color: "#829f",
width: 8
})
);
}
