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?

If you are comfortable with old DOS commands, you can use the
following to concatenate multiple IGC files and submit the result to
the Range Analyzer.

- Put the IGC files of interest in a temp directory
- Open a 'cmd' shell in the directory of your IGC files.
- Enter the command: type *.igc all.igc
- Upload all.igc to the range analyzer

There is an upper limit to the size of the file the Range Analyzer can
handle, so the number of files concatenated is not unlimited.
