I have run several flights through the PowerFlarm range tool, and my coverage seems adequate, but I am wondering if anyone has a method of determining 3D coverage? The tool shows a decent depiction of horizontal coverage, but I wouldn't mind having an idea of the coverage above and (especially) below.

Also, in a previous thread, one poster (mark...@lennoxengineering) mentioned he had developed a tool to splice together several flights. Is this available for others' use?
