Post by a***@gmail.comGreetings, does anyone have a calculation that calculates the new
latitude and longitude based on a starting point, bearing and
distance?
I would greatly appreciate any help people might have.
Many Thanks,
Aaron
Art,
Thanks so much for the link. I've been fiddling around with the
formulas and can't seem to get it to work. I get a plausible Lon2, but
the Lat2 is a negative decimal. Might you have any suggestions as to
what I'm doing wrong? Thanks again for the very helpful link.

lat2: =ASIN(SIN(lat1)*COS(d/ER) + COS(lat1)*SIN(d/ER)*COS(brng))
lon2: =lon1 + ATAN2(COS(d/ER)-SIN(lat1)*SIN(lat2), SIN(brng)*SIN(d/ER)
*COS(lat1))
Lat1
43.067833
Lon1
-89.525639
Bearing
90
Distance(KM)
10
Earth Radius (KM)
6374
LAT2 = -0.914704544 = ASIN(SIN(43.067833)*COS(10/6374) + COS(43.067833)
*SIN(10/6374)*COS(90))
LON2 = -89.52818005 = -89.525639 + atan2(sin(90)*sin(10/6374)*cos
(43.067833), cos(10/6374)-sin(43.067833)*sin(lat2))
