The User-friendly Desktop Internet GIS for OpenGIS Spatial Data Infrastructures
project (uDig) will create an open-source desktop GIS application, to make
viewing, editing, and printing data from CGDI and local data sources simple for
ordinary computer users.

Open-source components are a critical part of the CGDI vision, because they
allow organizations to deploy infrastructure widely, in a distributed fashion,
without incurring multiple licensing fees. Open-source components are also the
most tractable for fast support of new OpenGIS interoperability standards.

There are already many different pieces of open-source software that implement
OpenGIS server standards: Mapserver implements WMS, GeoServer implements
WMS and [WFS-T], Postgis implements [SFSQL], DeeGree implements WMS and
WFS, and so on. However, there is not a single piece of desktop software capable
of binding information from all these servers together into a unified desktop view.
uDig is the open-source application which will bring CGDI data sources to the
desktop, and integrate them with local data sources for standard business
processes — data viewing, data editing, and data printing.
