For larger-area basemaps, satellite imagery providers make more sense: and Australia and has a very simple user interface available through any web browser. For high-resolution aerial imagery, NearMap orthographics provide great coverage in the U.S. Rather than license imagery from Google that they’re, in turn, licensing from imagery providers, it usually makes more sense to go directly to the source.

Different types of clouds reflect in different amounts based on their physical properties like amount and size of raindrops / ice crystals and its density. Visible imagery is very useful for distinguishing clouds, land, and sea/ocean. The amount of reflection depends on the type of reflective surface. The incoming solar radiation in this channel is reflected by Clouds and Ground. Hence this channel is known as the Visible channel. The channel (0.65µm) lies in the visible region (0.4µm - 0.7µm) of the electromagnetic spectrum which can be seen with naked eye.
