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
Web users especially require a flexible library of images for their map styles. We fill this need with an improved Image Manager for our Styler application.
Map Styling Tools (SLD editing)
A premier feature of GeoExt will be a powerful style editor, built on the SLD standard, that can be integrated in to any application to let users change how the map looks. This will build on the work of Styler, improving and integrating those components to allow standalone SLD editing in addition to server-side style administration. It should support a variety of user friendly tools to create complex styling rules with ease.
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.
