[back to package description]Jord - Geographical Position Calculations
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?
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"
