Jord - Geographical Position Calculations

travis build status Hackage license

Jord [Swedish] is Earth [English]

What is this?

Jord is a Haskell library that implements various geographical position calculations using the algorithms described in Gade, K. (2010). A Non-singular Horizontal Position Representation.

How do I build it?

If you have Stack, then:

$ stack build --test

How do I use it?

See documentation on Hackage

import Data.Geo.Jord

-- destination position from 531914N0014347W having travelled 500Nm on a heading of 96.0217°
destination (readGeoPos "531914N0014347W") (decimalDegrees 96.0217) (nauticalMiles 500)

-- distance between 54°N,154°E and its antipodal position
let p = latLongDecimal 54 154
distance p (antipode p)

Jord comes with a REPL (built with haskeline):

$ jord-exe
jord> finalBearing (destination (antipode 54°N,154°E) 54° 1000m) 54°N,154°E
jord> angle: 126°0'0.0"
