Advanced Wind Field Analysis
Making more of what we already have
The boat tracks contain more information about the wind than we currently extract. There is spatial information based on where the boats are. If two boats are near to each other at a given time and sail on different tacks, this increases the local confidence of the wind estimation at that point. If boats close to each other at the same time but different location lead to a different estimation, this can let us estimate a position-dependent wind field.
Also, we need to improve the accuracy of the current estimator. See also bug 240.
If we get measurements from more than one wind sensor, we usually also receive the sensor's position. We currently don't use this information in answerin queries for wind data at a time point and a position. We should come to a pragmatic interpolation algorithm that at least roughly understands the air flow across the race course area. To a degree this is also touched by bug 1201.
