GeoExt BasicsΒΆ

GeoExt is a young, rapidly-developing library for building rich, web-based GIS applications. The library is built upon Ext JS and OpenLayers. The former provides UI components for building web applications along with solid underlying data components, the latter is the de-facto standard for dynamic web mapping.

GeoExt provides mapping related UI components. It also unifies access to information from OGC services, OpenLayers objects and arbitrary remote data sources. This allows for easy presentation of geospatial information in a wide choice of widgets, ranging from combo boxes or grids to maps and trees. It has a friendly API, reduces the number of lines of code required, and results in engaging and responsive mapping applications.
