Usually, I keep my "bigger" projects out of my personal blog but maybe it's time to change that. Since 2007, I'm running "The Finnish Weather Center", a website which provides free weather maps and a little bit of background info for storm chasers and others who are interested in (severe) weather. Already a year ago, I had some ideas and started to redesign the website which to date is running on Joomla. It quickly turned out that the ideas I had required much more than a simple redesign of the website and due to the amount of work and my lack of time, I shelved the project then.
While the old UI would show you discrete maps for each parameter on different pages, the new UI is based on the Open Source map display web app Leaflet. Basically, the whole screen is a huge map and you chose what you want to see (aka overlay) on that map. I personally like this approach much more and the analysis workflow seems much more fluent to me this way.
