About GeoExt
GeoExt is a JavaScript library that provides a groundwork for creating rich web mapping applications. It combines the web mapping library OpenLayers with Extjs, "a cross-browser JavaScript library for building rich internet applications." GeoExt provides a suite of customizable widgets and data handling support that makes it easy to build applications for viewing, editing, and styling geospatial data.
- Built with Ext JS, cross-browser rich Internet application framework
- Integrated OpenLayers mapping client
- Full dynamic user interactivity and animation without the need for Flash or Silverlight
- Well designed and extensible component model
- Wide variety of generic widgets (grids, charts, trees, layouts, combo boxes, toolbars)
- Flexible, standards-based mapping widgets like legends, pop-ups, and scale choosers
- Printing controls from PDF serving platform, such as page layouts, resolution, and legends
- Customizable layer selection
GeoExt Applications
GeoExt makes it easy to build web mapping applications like the ones below:
- Styler: An interactive styling application for geospatial data.
- GeoExplorer: A tool for browsing geospatial data on the web

Recent Contributions
OpenGeo is one of the founding partners in the development of GeoExt. We have many committers on staff and fund GeoExt core and application development.
Working closely with other members of the community, our developers have had a hand in every component of GeoExt, including:
- The map panel, layer tree, legend and Popup widgets.
- The store classes that facilitate easy handling of data within GeoExt applications.
Core Development Roadmap
GeoExt should provide components that make it easy to export the current map to a variety of formats. Foremost among these is embedding the current view to a webpage or blog. Past that it would be great to export in a variety of formats, like Google Earth, PDF, or as another GeoExt application with alternate controls.
Versioned Editing Toolbar and Components
There have been several applications making use of the WFS-V 'versioning' protocol of GeoServer, to do operations like History, Diff and Rollback in addition to the standard editing. These should have default components in GeoExt so people can easily add rich versioning capabilities to their applications
Many applications will need to allow users to logon to a remote server, be it for remote administration, editing of data, or controlled view access. GeoExt should have a default manager for logging on, with different options for the backend login mechanism and desired front-end gui dialog.
