While working with Insurance Australia Group, I wrote a web-mapping framework based on the excellent Bootleaf application by Bryan McBride.
The goal was to enable users to create web mapping applications quickly and with a minimum of manual intervention. The application supports a variety of widely-used GIS standards such as ArcGIS Server (feature, tiled and dynamic layers), WMS, WFS and GeoJSON. Additional functionality includes querying, identify, basemaps, and other widgets as required by a diverse group of insurance end-users.
Bootleaf is used in many active applications within IAG and has helped to enable rapid map creation in the event of disasters, and a reduction in the time required for staff to maintain web maps.
