Hi all,
I would like to know a way of calculating the distance between 2
points when
I already have the longitude and latitude of the points.
For example :
Point 1 : 52° 9'54.00"N 4°25'8.40"E
Point 2 : 52°27'46.80"N 4°33'18.00"E
Distance between point 1 and point in km ....
Is there any functions already available for this ?
Searching on: distance points longitude latitude
gdist {Imap} Geodesic distance (great circle distance) between points
Ellipsoidal.Distance {GEOmap} Ellipsoidal Distance
deg.dist {fossil} Haversine Distance Formula
distaz {RSEIS} Distance and Azimuth from two points
distaz {GEOmap} Distance and Azimuth from two points (# one probably
borrowed from the other)
AlongGreat {RFOC} Get Points Along Great Circle
distAB {clim.pact} Distance between two points on Earth
Any help will be much appreciated!
Suggest you learn to search.
