Top End and Gulf map now contains all-new digital cartography with GPS surveyed roads and tracks. Many major road and track junctions on the map have GPS coordinates, and there's a handy index of towns and localities with GPS coordinates. Another new feature is the inset maps which show more detail, including many 4WD tracks and walking trails. The Darwin Region inset covers popular destinations such as Kakadu and Litchfield national parks. Insets are also provided for Gregory National Park, Keep River National Park, Nhulunbuy and Boodjamulla (Lawn Hill) National Park.
