Why is Thuban being developed?

[2001:] The FreeGIS Project provides an overview of Free Software GIS projects. Many valuable and highly sophisticated tools exist, but there is still a need for a user-friendly, interactive viewer for geographic information.

Thuban makes use of several Free GIS Software components and is itself the basis of advanced GIS applications, e.g GREAT-ER desktop

The project name Thuban originates from the alpha-star in the constellation Draco, the Dragon. It was the pole star when the Egyptians built the pyramids.

<em>The Thuban Main Window falls into five major parts: </em>

* Map

<em>Layer Properties</em>
Aside the layer title the properties dialog mainly focusses on the legend: The layers objects can be grouped by single values or ranges. Visibility and symbols can be edited per group.

<em>Automatic Classification</em>

Thuban supports explorative data analysis with automatic classifications of data. Supported are:

* unique values,
* uniform distribution and
* quantiles.

The number of groups is flexible, a ramp of symbols is generated for the resulting classification.

<em>Projections</em>

Thuban is distributed with a sample collection of projections and the set of coordinate systems as used by the EPSG (European Petroleum Survey Group).

For full flexibility projections can be assigned to the map and to each separate layer.

<em>Table Management</em>
