⚠️There's a newer version (1.0-20) of this package.Take me there.

sf (version 0.6-0)

Simple Features for R

Description

Support for simple features, a standardized way to encode spatial vector data. Binds to GDAL for reading and writing data, to GEOS for geometrical operations, and to Proj.4 for projection conversions and datum transformations.
