(...) Oops, there was a mistake in my first equation above that I've corrected here, in order to give a negative number. (...) That's why I have " > 180", not "> or equal to 180" ;) Since the question was framed in relation to 0, that's what my (...) (21 years ago, 5-Aug-05, to lugnet.org.ca.rtltoronto)

(...) I noticed that, also. I think it says "changes must be less than 180". However, I'm not sure it matters which direction you went. For example, if you get readings of 10 deg and 20 deg, but in the time between the direction was never 15 (...) (21 years ago, 5-Aug-05, to lugnet.org.ca.rtltoronto)

(...) One of the things I did pickup from "my" answer is you need to have a sample frequency small enough that you are not going to get wind direction changes of 180 degrees or more. And I say or more, because it's important to the average which (...) (21 years ago, 5-Aug-05, to lugnet.org.ca.rtltoronto)

(...) And if you stop and think about it for a second or two, you'll realize your special case really does deserve special consideration. The average is no wind at all, so the direction would be undefined. (21 years ago, 5-Aug-05, to lugnet.org.ca.rtltoronto)

(...) Don't you get the same problem at 180, now? 170 + 190 = 170 +(-170) = 0 I think there are several readings that can give you more than one result. For example, if you take two readings of 90 and 270, what should the answer be? 0? 180? never (...) (21 years ago, 5-Aug-05, to lugnet.org.ca.rtltoronto)

(...) If I remember right, the way we resolved this for real-world surveying problems and the like was to convert the degrees 180 < x < 360 into negative values relative to 0/north. 350 is -10, 270 is -90, etc. If x1 > 180 then x2 = 360 - x1 This (...)
