We've already made some progress on building a CIC google map. We will be able to show a geographical representation of CICs throughout the country, and can integrate different search criteria so that the map is useful for a number of different search criteria.
This link takes you to an early version,showing England excluding London. With a good search facility and improved graphics this could be a fantastic tool with a number of uses.
So far we plan to be able to search
by area, by sector, whether cls or clg,
If your looking for investment and/or other types of support
Whether you are in a qualifying geographical area for various different forms of govt support eg whether or not an investment in your CIC could qualify for CITR tax relief
Please let us know your thoughts and ideas regarding what data sets you might want included
