R bindings to the liblwgeom library
This package provides functions that use
liblwgeom, including st_geohash,
st_minimum_bounding_circle, st_split, st_subdivide,
st_transform_proj (transform through proj, omitting
GDAL) and st_as_sfc.TWKB (creates sfc from tiny
wkb),
as well as the geodetic (spherical/ellipsoidal) geometry
functions st_geod_area,
st_geod_length,
st_geod_distance,
st_geod_covers,
st_geod_azimuth,
and st_geod_segmentize. The previously offered st_make_valid
is now a generic in package sf.
lwgeom depends on sf, which
has to be installed first. This package uses the liblwgeom library,
and compiles a shipped (and modified) version of liblwgeom. It links
to the GEOS and PROJ libraries.
To install from source, it should be enough to have installed
sf from source; the resources for this package (PROJ, GEOS)
are being reused.
Previous to version 0.1-6, lwgeom would also try to link the system
library liblwgeom; from 0.1-6 on only the shipped version is used.
