GeoExt

GeoExt is an open-source JavaScript library that helps developers create web applications for mapping and geographic information systems (GIS). It combines the powerful mapping capabilities of OpenLayers with the user interface features of Ext JS. This allows developers to build interactive maps and applications that can display, analyze, and manage geographic data easily. GeoExt is designed to make it simpler to work with maps on the web, enabling users to visualize location-based information in a user-friendly way, making it suitable for various applications, from environmental monitoring to urban planning.
