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
Unique Values and Thematic Maps
Styling interfaces for thematic mapping require the classification of data, and the assignment of styles to each classification. This item would create a user interface for managing the style groups in a thematic map, and displaying the unique values in categorical data layers.
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.
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.
