This is an ancillary function to mat.dissim that calculates distance in meters on a sphere between two points of longitude/latitude
1 | great.circle.distance.f(cLonLat, oLonLat)
|
cLonLat |
Vector: with two values, one of longitude and the other latitude. |
oLonLat |
Vector: with two values, one of longitude and the other latitude. |
The calculation is based on a sphere of 6374 km diamater. The user can change this for other spheres or earth models.
A single value of distance in meters.
