Sure Steve,
The DVD is just the format for delivery of such a large file (the map is an image file stored on the DVD). You then put the DVD into your
home computer and copy the file off the DVD to your computer.
The use of digital mapping is very commonplace and widespread - For more information, may I recommend that you view the articles we have provided on this topic in our Navigation section (as linked).
You can find your own way to the articles by using the blue site menu at the top, click on Topics, go to Navigation and browse through the various articles there.
Enjoy!
