nvctr package implements the n-vector approach to geographical position calculations using an ellipsoidal model of Earth as described in (Gade 2010).
You can install the development version of
nvctr from GitHub with:
or the CRAN version (when this package will land to CRAN):
nvctr can be used to solve geographical position calculation like (example numbers refer to the ones in the vignette):
- Calculate the surface distance between two geographical positions (Example 5).
- Find the destination point given start point, azimuth/bearing and distance (Example 8).
- Find the mean position (center/midpoint) of several geographical positions (Example 6).
- Find the intersection between two paths (Example 9).
- Find the cross track distance between a path and a position (Example 10).
