Introduction
In this article we will see how to draw a polygon on Nokia Maps.
Prerequisites
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"
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 Coordinates 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
<html>
<head>
<script type="text/javascript"
src="http://api.maps.nokia.com/2.0.0/jsl.js" charset="utf-8">
</script>
<link rel="stylesheet" href="style.css" />
</head>
<body>
<div id="map" style="width:100%; height:80%;"></div>
</body>
<script type="text/javascript">
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 nokia.maps.map.Display(document.getElementById("map"), // new instance of Ovi Maps
{
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':[53.1, 13.1]
});
map.set("baseMapType", map.SATELLITE);
//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.
*/
map.objects.add(
new nokia.maps.map.Polygon(myGeoStrip,
{
precision: 36,
simplify: 16,
fillColor: "FFFFCC",
color: "#829f",
width: 8
}));
