sphericalDistance: Calculate distance between two points along great circle...

In drodriguezperez/whereiam: whereiam: Geolocation package and spherical trigonometry calculations

Description

The function calculates distances between the two points along great circle using the Spherical Law of Cosines formulae. This is the shortest distance over the earth's surface ignoring the geographic shape like hills and vales.

Usage

  sphericalDistance(...)

  ## Default S3 method:
 sphericalDistance(latitude1,
    longitude1, latitude2, longitude2, units = "km", ...)

  ## S3 method for class 'Coordinate'
 sphericalDistance(coordinate1,
    coordinate2, units = "km", ...)

Arguments

latitude1	the first latitude coordinate
longitude1	the first longitude coordinate
latitude2	the second latitude coordinate
longitude2	the second longitude coordinate
units	a string with the distance units (default kilometers)
coordinate1	the first coordinate class variable
coordinate2	the second coordinate class variable
...	other arguments

Examples

cord1    <- Coordinate(43, -8)
cord2    <- Coordinate(42, -7)
distance <- sphericalDistance(cord1, cord2)
