I don't know about this. I'm from Manitoba, and it shows large swathes of land that have been apparently decimated (or conversely, massively planted). However, driving through many of those areas on a regular basis as I do, I have not seen the same changes reflected on the ground, so to speak. I'm curious as to how this system handles things like cloud cover in the satellite imagery, shadows (i.e.: time of day), seasonality, etc. Something seems amiss, at least in the areas I can personally vouch for.
