Hi,

I'm envisioning something like a Google Maps overlay that has color-
coded points or blobs based on the average vario reading or climb-rate
in a given area. Obviously you would need a certain number of
overlapping or nearby data-points to generate a decent average.

Akaflieg Frankfurt have done something similar. See:

http://www.akaflieg-frankfurt.de/ind...t/LIFT-Projekt

for a paper describing the project (sorry, german only) and

http://www.akaflieg-frankfurt.de/ind...t/Thermikkarte

for the actual implementation.

Ciao, MM
