Dear list members I have found three functions for calculating the distance between geographical points, 'geo.dist' in the 'oce' package, 'rdist.earth' in the 'fields' package, and 'spDistsN1' in the 'sp' package. They all give slightly difference answers, so my question is: which of them is best, i.e., gives the most accurate answer?
When it comes to performance, the 'rbenchmark' package shows that (at least on calculating a single distance), 'spDistsN1' is the fastest, 'geo.dist' takes twice as long, and 'rdist.earth' takes about five times as long (as 'spDistsN1'). -- Karl Ove Hufthammer _______________________________________________ R-sig-Geo mailing list R-sig-Geo@stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-sig-geo
