My thoughts:
-This is amazing, your ability to present large data sets is unmatched.
-The turtle speed is still far too fast for the minimum speed. When looking at radar loops I like at least half a second between so I have time to scan the area
-This may be because I'm used to Environment Canada's radar images, but is there a way to view it unsmoothed?
I'm a marine forecaster, and your site has become an invaluable tool for me. I can't sing your praises loud enough (and sing them I do, I throw the url at anyone who will listen!), a sincere thank you.
