Prerequisites

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 Location API Business Models and Usage Restrictions 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 from the Nokia Developer API Registration page.

Implementation

API Definition of Rectangle:

    new nokia.maps.map.Rectangle (bounds, props)

Definition for the BoundingBox, used to form the rectangle:

new nokia.maps.geo.BoundingBox (topLeft, [bottomRight, [skipValidation]])

Example code

This is a full example with HTML and JavaScript.
