flight-earth

A set of solutions to geodesy problems in various programming languages; in Haskell, F#, Unison, Koka, Lean, and Rust.

The Direct or Forward Problem

  • {x} The departure point on the ellipsoid.
  • {α₁} The azimuth from the departure point.
  • {s} The distance to the arrival point.

Given the above inputs, find:

  • {y} The arrival point.
  • {α₂} The azimuth at the arrival point.

The Inverse or Reverse Problem1

  • {x} The departure point.
  • {y} The arrival point.

Given the above inputs, find:

  • {s} The distance between departure and arrival points.
  • {α₁} The azimuth at the departure point.
  • {α₂} The azimuth at the arrival point.

Footnotes

  1. Sometimes called the indirect problem.
