Roadmap Items
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
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.
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.
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.
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.
Editing Toolbar and Components
While there is rich editing available in OpenLayers there are no good default toolbars to make use of these in GeoExt. A good editing toolbar should be modular, to incorporate the type of editing that people want to make available to their users. It should also establish good defaults for pop-up and grid based attribute editing, and work well with the different OpenLayers persistence mechanisms.
Creating new geometry from COGO directions is a common use case for web editing tools in county and municipal jurisdictions. This work item will create a GUI for users to enter COGO directions and return traverse data model suitable for converting to a feature or serializing to a database.
