Bindings for the 'Geospatial' Data Abstraction Library

Provides bindings to the 'Geospatial' Data Abstraction Library ('GDAL') (>= 1.11.4) and access to projection/transformation operations from the 'PROJ.4' library. The 'GDAL' and 'PROJ.4' libraries are external to the package, and, when installing the package from source, must be correctly installed first. From 'rgdal' 1.4.1, provision is made for 'PROJ6' accommodation, with 'PROJ6' functionality to follow; from 1.4.1 'rgdal' will build and function when 'PROJ' >= 6. Both 'GDAL' raster and 'OGR' vector map data can be imported into R, and 'GDAL' raster data and 'OGR' vector data exported. Use is made of classes defined in the 'sp' package. Windows and Mac Intel OS X binaries (including 'GDAL', 'PROJ.4' and 'Expat') are provided on 'CRAN'.

SystemRequirements for building from source: GDAL >= 1.11.4, library from https://trac.osgeo.org/gdal/wiki/DownloadSource and PROJ.4 (proj >= 4.8.0) from https://download.osgeo.org/proj/; GDAL OSX frameworks built by William Kyngesburye at http://www.kyngchaos.com/ may be used for source installs on OSX. For installation with older external dependencies, override configure checks with --configure-args="enable-deprecated=yes". Consider source installations using archived versions of rgdal contemporary with installed external dependencies, for example rgdal_0.8-7 for PROJ4 4.8.0 (March 2012).
