One of the tasks Google Earth Pro is really useful is getting a quick idea of the viewshed from a specific location. This is particularly useful for planning solar installations or other infrastructure projects such as LoRaWAN gateway deployments.

Whilst the tool is quite powerful, it has a very limited viewshed (roughly 5km) and this is not really useful when looking at gateway deployments that in flat regions of Australia easily can reach 25km+. Also it is not at all obvious how to modify the radius of the viewshed since that has not been a feature in the GUI and it is not documented at all.
