Simple Features for R

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' for projection conversions and datum transformations.

Functions in sf

Name Description
gdal functions to interact with gdal not meant to be called directly by users (but e.g. by stars::st_stars)
is_driver_available Check if driver is available
is_driver_can Check if a driver can perform an action
sf_project directly transform a set of coordinates
Ops S3 Ops Group Generic Functions for simple feature geometries
aggregate.sf aggregate an sf object
geos_unary Geometric unary operations on simple feature geometry sets
geos_measures Compute geometric measurements
geos_query Dimension, simplicity, validity or is_empty queries on simple feature geometries
internal Internal functions
st_bbox Return bounding of a simple feature or simple feature set
st_cast Cast geometry to another type: either simplify, or cast explicitly
