We've been working on porting the SLC Open GeoPortal application over to the GeoExplorer platform. GeoExplorer is a component of the OpenGeo Suite, developed by OpenGeo. GeoExplorer provides a much more scalable platform which is also easier to maintain and update, however we wanted to retain some of the advanced functionality from the existing OpenLayers/ExtJS site- specifically tax parcel search capabilities, municipal quick zooms, and an organized tree structure for the layer list. I'm documenting my modifications and posting them on my blog for anyone who may be interested in hacking their own GeoExplorer!

The application utilizes a GeoServer back-end to serve up large GIS datasets to a user-friendly OpenLayers web client. This website will give residents tremendous access to public GIS data and services which were previously unavailable due to the lack of a decent distribution platform.
