Thuban is an interactive geographic data viewer. It has been developed because|
there was no simple interactive viewer for geographic information available as
Free Software. Thuban is written in Python and C++ and uses the wxWindows
library allowing it to run on many different platforms, including GNU/Linux and
Geographic data viewers are a necessary tool as they allow one to get a visual
impression of the positional relationship of the information that may not be
apparent from simple inspection of the data values themselves. Thuban allows
the user to create a session that displays geographic data and then explore
that data through navigation and manipulation of how it is drawn. The results
can then be saved or printed.
Thuban arranges a session in a hierarchy. A session contains a map which
consists of layers. Each layer represents one kind of data set. For instance,
there may be a layer for roads and another layer for buildings. These layers
can either be vector shapes or images.
