Hi,
I am sure I am well behind the curve, but just seen that the Environment Agency (who I ironically work for) have now got real time river levels in the web. There are a few companies that make the data available e.g. Www.shoothil.com. I have embedded a couple of widgets into my site.
I have also noticed that the Environment Agency now provide API to allow people access to the real time data. I was just wondering if there was anyone out there much cleaverer than me that would be able to write a script that could reduce real time graphs of a selected river level location? Web site location is:
