This database produces major rivers (and some lakes) which may be used to add to an existing map. Unfortunately, there is no fine control over which rivers are plotted, so all rivers which lie within the boundaries of the current plot on display will be added. Some of these may be outside the boundaries of the map shown.
This world database comes from a cleaned-up version of the CIA World Data Bank II data and contains approximately 2 million points representing the world coastlines and national boundaries. This makes it suitable for extracting countries, continents, etc. while still retaining lots of detail.
