Why did Shoothill create FloodAlerts?

• Uniquely, FloodAlerts receives a raw data feed from the Environment Agency and converts the data into Bing Maps polygons as a Bing Maps tile layer (on the fly)

• Alert data is updated every 15 minutes (24 X 7)

• Flood Tiles are displayed (in situ) on Bing Maps as different coloured ‘shape’ file tiles representing the severity of each Flood warning

• Any ‘pins’ (i.e. properties under surveillance for flood) placed within the flood alerts warning areas can be highlighted to inform the end user that they are under potential risk (email, Phone app and soon...text)

• End users can register a 1 or 2 properties for free (except SMS)

• IPhone, Win 8, (Ipad / Android soon)

• Designed to be easily Iframe’d into any portal / partner site

• Everything runs from the cloud (on MS Azure)
