*Post by a***@gmail.com*Greetings, 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.

Aaron

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))
