For you tech heads out there...this is how the Canadians are monitoring and mapping lake ice with radar satellites.

They can tell the state and condition.

Since the Canadian own a couple commercial radar satellites (and the USA doesn't have any), they can easily provide this service like weather reports. NOAA could and should be doing this as a service considering the number of people who drown each year for going out on unsafe ice.
