along.great: Along A great Arc

Description

Calculate points along a great arc

Usage

along.great(phi1, lam0, c, Az)

Arguments

phi1

start lat, radians

lam0

start lon, radians

c

distance, radians

Az

Azimuthal direction, radiansm

Value

• List:
• phi
  latitudes, radians
• lam
  longitudes, radians

Details

All input and output is radians

Examples

lat1 <- 48.856578
lon1 <- 2.351828	

A = along.great(lat1*pi/180, lon1*pi/180, 50*pi/180, -63*pi/180)

lat=A$phi*pi/180
lon = A$lam*pi/180
