Hey guys!

I have an Point A and i want to find an Point Bs real world coordinates.

Given for that is:

  • The Lat and Longitude of A
  • The angle that A is facing (faces B)
  • The distance in meters between A and B

I have found this resource (https://www.wyzant.com/resources/answers/601887/calculate-point-given-x-y-angle-and-distance) but i am looking for the real world coordinates, not the coordinates in an coordinate system.

Please @neon crown when responding

@neon crown is this on a sphere?

As i said, real world coordinates

#

yeah it's gonna be a whole lot more complicated then I assume you think it will be

neon crown
#

You think that because?

#

the link you supplied is on a 2d plane

#

and it gets a lot more complicated with spherical coordinates

#

so r phi and theta

#

Yea ofcourse

#

you could do it with slicing, and it won't always be accurate because the earth is an oblate spheroid

#

distance is the arc length, you can use that to calculate the degrees of difference from point A, projecting a circle with that arc length away from A around A. From here you use the bearing, sine and cosine to calculate the difference in latitude and longitude with the given arc length

looks good to me
