uDig – User-friendly Desktop Internet GIS

User-Friendly Desktop Internet GIS (uDig) is an open source spatial data viewer/editor, with special emphasis on the OpenGIS standards for internet GIS, the Web Map Server and Web Feature Server standards.

uDig aims to be:

  • User friendly – providing a familiar graphical environment for GIS users.
  • Desktop located – thick client.
  • Internet oriented – WMS, WFS, WCS, GeoRSS, KML, tiles geospatial web services.
  • GIS ready – providing the framework on which complex analytical capabilities can be built, and gradually subsuming those capabilities into the main application.

It is a Java based open source desktop application framework, built with Eclipse Rich Client (RCP) technology.

Features include:

  • An out-of-the-box application, with the ability to view, edit and print files, database (Oracle, SDE, PostGIS) and Web Feature Servers (WFS).
  • An industry-standard extension framework (RCP) for adding new functionality to the application.
  • A rich toolkit of Java functionality, ready for developers to build on.
  • Uses GRASS for complex vector operations.
  • PostGIS.
  • WMS.
  • Desktop Client with Drag and Drop integration for File explorer and Web Browser.
  • Integrate with your existing infrastructure: ArcSDE, Oracle, DB2 and more.
  • Work with local files: Shapefile, jpeg, png, tiff and more.
  • Work with advanced spatial raster formats: ECW, MrSID, JPEG 2000.
  • Support for compliant Web Map Servers (GeoServer, MapServer tested).
  • Integrated Web experience with an embedded browser that recognises OGC web services and smoothly adds links to the onscreen map.
  • Style Layer Descriptor control of rendering allowing you to publish your Map using the same settings in uDig as with popular Web Map Servers.
  • Deep integration of standards allowing the application to swap between the appropriate service as required for display, interaction and editing.
  • Printing and PDF Generation.
  • Native support for many other data sources.
  • Cross-platform support – runs on Linux, Mac OS X, and Windows.
