A package that provides simple features access for R. Package sf:
- represents natively in R all 17 simple feature types for all dimensions (XY, XYZ, XYM, XYZM)
- uses S3 classes: simple features are
data.frame
objects (ortibbles
) that have a geometry list-column - interfaces to GEOS to support the DE9-IM
- interfaces to GDAL with driver dependent dataset or layer creation options, Date and DateTime (
POSIXct
) columns, and coordinate reference system transformations through PROJ.4 - provides fast I/O with GDAL and GEOS using well-known-binary written in C++/Rcpp
- directly reads from and writes to spatial databases such as PostGIS using DBI
- package vignettes: first, second, third, forth, fifth, sixth
- blog posts: first, second, third, fourth
- the original R Consortium ISC proposal, the R Consortium blog post
- presentations: rstudio::conf 2018, UseR! 2016
- wiki page describing sp-sf migration
Install either from CRAN with:
install.packages("sf")
this will install binary packages on Windows and MacOS, unless you configured R such that it tries to install source packages; in that case, see below.
Install development versions from github with
library(devtools)
install_github("r-spatial/sf")
Installing sf from source works under windows when Rtools is installed. This downloads the system requirements from rwinlib.
One way to install the dependencies is using sudo
; the other is using homebrew. For the latter,
see e.g. here. Homebrew commands might be:
brew unlink gdal
brew tap osgeo/osgeo4mac && brew tap --repair
brew install proj
brew install geos
brew install udunits
brew install gdal2 --with-armadillo --with-complete --with-libkml --with-unsupported
brew link --force gdal2
after that, you should be able to install sf
as a source package.
For MacOS Sierra, see these instruction, using kyngchaos frameworks.
For Unix-alikes, GDAL (>= 2.0.0), GEOS (>= 3.3.0) and Proj.4 (>= 4.8.0) are required.
To install the dependencies on Ubuntu, either add ubuntugis-unstable to the package repositories:
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update
sudo apt-get install libudunits2-dev libgdal-dev libgeos-dev libproj-dev
or install dependencies from source; see e.g. an older travis config file for hints.
The following command installs all required dependencies:
sudo dnf install gdal-devel proj-devel proj-epsg proj-nad geos-devel udunits2-devel
Get gdal, proj and geos from the main repos and udunits from the AUR:
pacman -S gdal proj geos
pacaur/yaourt/whatever -S udunits
To install on Debian, the rocker geospatial Dockerfiles may be helpful. Ubuntu Dockerfiles are found here.
Functions and methods that require liblwgeom
, including st_make_valid
and all spherical or ellipsoidal metrics (area, distances), have since sf 0.5-5 been moved to their own package, lwgeom, which is also on CRAN.
