How to quickly verify .igc gps log files

Here is a very quick and easy way to check .igc files before you upload them up to Leonardo or XCContest.

This is an free online tool that allows quick viewing of a .igc tracklog file. There is no registration or other information required, just upload the file and click View.

The detailed flight analysis is quite neat. It has a useful feature that shows thermals and transitions with average climb rates, something Leonardo does not do.

Thermals are marked in green, transition or glides in red. The flight analysis even shows which way you turned in the thermals. From the table below it's clear I have a preference for turning left...

This is nice to provide a little big more analysis about the day and see how strong the thermals were. You can see in the screenshot from the Average Vs (m/s) column that this was a very slow day.
