Everyone should be familiar with the video technique of traveling across a map used in movies like Indiana Jones and documentaries similar to the example shown here.
This can be a great way to start a documentary clip for a museum exhibit or other digital signage project such as a promotional video in a travel agency and it is very easy to create. While a couple of software packages such as Road Trip Effects (Mac/PC) from Sol Robots provide dedicated tools the latest version of iMovie (Mac) includes a very simple and intuitive function that was used to create the example above.
To access it in iMovie simply select the Maps and Background browser in the iMovie main page as indicated in the picture here. Select a map style and drag it to the project window. A dialog box may open otherwise double click on the video in the Project window, this will allow you to set the duration and other settings.
