Hi, What do we want to accomplish? We want to know where to look for thermals. I don't think that connecting gliders on-line will get us there.
I think a more promising approach would be to evaluate MANY flight logs (IGC files). I heard this idea before but I am not aware of any (publicly available) results. The idea, as far as I understand, is to evaluate flight logs to see where climb rates were measured, and correlate this with the wind conditions, the time of the day, temperature, and maybe a couple more parameters. The assumption is that thermals build up always in the same spot under certain conditions. I guess we all agree to that. Ideally we would like to get access to all IGC files that were uploaded to OLC over the years. If we can't get that, we can always decide to setup our own Web based facility where pilots can upload IGC files and also download the result of the statistical analysis of all flight logs for a certain region. That result would be a loaded to your PDX (much like a map file) from which XCSoar displays color coded probabilities of thermals given the current wind speed and direction, and the current time of the day.
