smallworld and google: the best of both worlds
DESCRIPTION
Presentation at the Smallworld User Conference in Baltimore, September 2010. Discusses work we have done to integrate Smallworld with Google Maps and create a very easy to use application which can access complex utility network data in a simple way. Also discusses advantages of running in the cloud and usability.TRANSCRIPT

The biggest single loss was in November when Alistair Darling, the Chancellor, revealed two CDs with personal details of 25 million child benefit claimants and their parents had gone missing in the post.Three weeks ago Ruth Kelly, the Transport Secretary, admitted that the details of three million learner drivers had gone missing when a hard drive was lost in Iowa.
Last February it emerged 80 passports are lost in the post every month.
Last month, CDs with personal information on thousands of benefit claimants were found at the home of a former contractor to the Department of Work and Pensions.
