Wonder if it is a 'work-in-progress' considering Austrailia now shows up as a tab on the main Radar page?
The velocity data and multiple tilts is a big plus, especially out west where the lowest-elevation scan is terribly beam-blocked. But what's with the 64nm range limitation? The imagery on the EC website has a much larger range (but only the lowest-elevation scan is available).
iMap weather also has integrated the Canadian Radars into their weather display. Hopefully this is a sign that Environment Canada has either loosened its rules on data redistribution, or reduced their fees to the point that more vendors can afford it.
