Convert input string values

Hi Gareth,

Would be great to try. Thanks in advance. In the meantime, I am doing an inventory on what alternative options there are for visualising polygons in a "Google Fusion like" alternative. I am working for a an organization with numerous reforestation projects that submit polygons to us. Now, all needs to be processed by hand... This is not manageable in the long term and a waste of time. I estimate that more people would welcome a flexible central platform where aggregate data can be processed, (eddited) and visualized and other desktop information could be integrated. I saw the requirements inventory of Yaw about an alternative for Google Fusion. I know there is finance available, the question is how to put development into action.
