As for how you're supposed to get the directions, By Pete LePage. You can convert Euler angles to a quaternion and back to non-equivalent Euler angles. How do I do a formula to state the true difference not numeric? For example, N (north) is 0 degrees, NbE (north by east) is 11.25 degrees, NNE (north-northeast) is 22.5 degrees, etc. The spatial reference provided must have an ellipsoid and datum matching those used by the source of the latitude/longitude string. hi , am make weather jquery from wunderground api , and my jquery his working good . The micro:bit measures the compass heading from 0 to 359 degrees with its magnetometer chip. This online calculator is created after the user's request, and it is just a convenient shortcut between Course angle and the distance between the two . Compass point between two locations. Use Math.PI and the degree to radian formula to convert the angle from degrees to radians. How to Calculate Average Direction? This is not to be confused with the elevation . PS. Valid compass entries are numeric degree designations from 0 degrees to 360 degrees (0 and 360 are the same direction, North.) Your challenge is to take a degree measure, and convert it into a direction on the 32-point compass. You *want* true north, you already HAVE magnetic north. A magnetometer is useful for "facing 123 degrees from north". There is ONLY a degree designation. C should now be a (2 x 2)-matrix. Set up your worksheet to pass the latitudes and longitudes of the start and end points as standard entries, then enter a formula to pass them to function distVincenty (). To convert radians to degrees, you multiply by 180 π. The declination of an object is its angle in degrees, minutes, and seconds of arc above or below the celestial equator. Convert wind direction degrees to text. \$\begingroup\$ "you can't just convert direction into a rotation matrix" somewhat contradicts the two other answers that show how you can indeed do that, with a little care in selecting an appropriate up vector. Probably easiest to add a new function to your script, something like convertDegreesToWindDirection (degrees) to take in the amount in degrees and then return the string of the wind direction. wind_dir % mutate (wd_cardinal = cut ( wd, breaks = c (0, directions$degree_max, 360), labels = c (directions$cardinal, 'n') )) wind_dir #> # a tibble: 6 x 5 #> date sn ws wd wd_cardinal #> #> 1 2007-01-01 84084 21.3 34.8 ne #> 2 2007-01-02 84084 19.9 37.8 ne #> 3 2007-01-03 84084 19.3 38.2 ne #> 4 2007-01-04 84084 21.7 15.1 nne #> 5 … The output message will contain the degree as a number.
