%description
K-nearest neighbor search for projected and non-projected 'sf' spatial
layers. Nearest neighbor search uses (1) C code from 'GeographicLib' for
lon-lat point layers, (2) function knn() from package 'nabor' for
projected point layers, or (3) function st_distance() from package 'sf'
for line or polygon layers. The package also includes several other
utility functions for spatial analysis.
