I don’t know how much I trust it though, I know the skies in King Lake region aren’t as dark as Heathcote due to the proximity to Melbourne but getting the same radiance value. Apparently just behind the YanYean reserve is as dark as the country regions  |
Interesting - Yes I see how it has them as similar radiance. I sometimes look at the "older" maps, usually the ATLAS 2015 (although it says "NEW" - You can select it on the menu "Base Layers & Overlays" on the screen Top right). I prefer the presentation of brightness units shown on this map as it is in mcd/m2 and also shows the equivalent SQM reading. On this map it shows the circumstances the way you've described them, as Heathcote about twice as dark (typical brightness<0.2 mcd/m2) VS behind Yan Yean
Reservoir (brightness of 0.3 to 0.4 mcd/m2).
VIIRS 2017 - Home 41, Bayside nearby 2.1, Yarra Junction (Easter Visit 2016) 0.2 or better
