GeoContent Plus is distributed with one module:
the module is not strictly necessary for the basic GeoContent Plus functionalities (Overview maps).
The geocoding module queries Google geocoding web service to obtain a latitude/logitude tuple from a string address.
The module shows a form where the user can enter an address or a zip code and optionally select one or mode GeoContent Layers, after the form submission if the web service found a location for the given address, the user is redirected to a page contaning a GeoContent Plus map, zoomed and centered to the found location.
An error message is shown if the location could not be found.
The component is fully configurable from the control panel.
A nice trick is to add the location address on the URL like this:: http://www.website.com/page-containing-geocoding-module?gc_address=milano+via+anelli+12
