In andresgmejiar/lbmech: A Package to Study the Mechanics of Landscape and Behavior

Great Circle Circumference

Description

Get the circumference of the earth given a known point and initial bearing from that point

Usage

GreatCircleCircum(lon, lat, b, n = 72, a = 6378137, f = 1/298.257223563)

Arguments

lon	Numeric. A known longitude along a Great Circle.
lat	Numeric. A known latitude along a Great circle
b	Numeric. The initial bearing defining the Great Circle
n	How many points along the great circle should be modeled? More points results in higher precision. Default is n = 72
a	Equatorial radius. Default is for WGS84
f	Ellipsoidal flattening. Default is for WGS84

Examples

circum <- GreatCircleCircum(-98.844, 19.693, , b = 175.8)
