# Simple Features for R

Canonical: https://gisforweb.com/tools/sf/

R package implementing the OGC Simple Features standard for spatial data in R.

sf is the R implementation of the OGC Simple Features specification. It stores geometries in data frames, adds coordinate reference system handling through PROJ, and exposes spatial predicates, joins and operations backed by GEOS. It is the usual foundation for vector analysis in R, sitting on GDAL for format I/O.
