When would I need to use the LandView 6 National DVD product?
The National DVD product was created for those users who require access to data and maps for the entire country over a local area network (LAN) or a local hard drive. If you don’t mind frequently exiting the LandView program to switch between the East and West DVDs or are comfortable with networking just the states on either the East or West DVD, you don’t need the National DVD version.
