Fast, Dependency-Free Geodesic Distance Calculations
Dependency-free, ultra fast calculation of geodesic distances.
Includes the reference nanometre-accuracy geodesic distances of Karney
(2013) <10.1007>, as used by the 'sf' package, as well
as Haversine and Vincenty distances. Default distance measure is the "Mapbox
cheap ruler" which is generally more accurate than Haversine or Vincenty for
distances out to a few hundred kilometres, and is considerably faster. The
main function accepts one or two inputs in almost any generic rectangular
form, and returns either matrices of pairwise distances, or vectors of
- bug fix in sequential calculation with cheap distances; thanks to @mem48
- Add georange function to calculate extreme ranges only; thanks to @marcosci
- Add 'paired' option to 'geodist()' function to calcualte pair-wise
distances between 'x' and 'y' matrices
- Improve handling of column names
