Ortungswinkel - locating angle - hans.mayer - 2015-10-02
dear all,
what is "ortungswinkel" ( locating angle ) ?
today i noticed a stroke at 02.10.2015 16:12:34.826867174 UTC
location of the lightning was Lat/Lon: -4.405123 / 18.224421
my possition is: 16 17' 1" East 48 8' 57" North --> JN88dd45at
www.lightningmaps.org tells me that Ortungswinkel is: 189 degress
accidentally i noticed i get a different value if i calculate the angle.
on my linux box i have a command line tool called "qth" which tells me 178 degrees.
if i use google earth the result is 177.55 deg which is as rounded value the same as qth's result.
but both are quite different from the result of lightningmaps.org
on other hand i can't believe that ightningmaps.org does bad mathematics.
so my question: what is this value for called in german "ortungswinkel" ?
kind regards
hans

Locating angle is not the direction between your station and the strike, but the angle between the stations around the strike.
On the bottom of the page is the description:
Quote:Locating angle: Max. angle of participated station around lightning position (in parenthesis: stations that weren't used for calculation). A value of 270° would be ideal, but a good locating is also possible on much smaller values.

hi Steph,
many thanks pointing me in the right direction.
yes, it was clear for me that this value must be something different than the direction to the stroke.
