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’ library. Use is made of classes defined in the ‘sp’ package. Raster and vector map data can be imported into R, and raster and vector ‘sp’ objects exported. The ‘GDAL’ and ‘PROJ’ libraries are external to the package, and, when installing the package from source, must be correctly installed first; it is important that ‘GDAL’ < 3 be matched with ‘PROJ’ < 6. From ‘rgdal’ 1.5-8, installed with to ‘GDAL’ >=3, ‘PROJ’ >=6 and ‘sp’ >= 1.4, coordinate reference systems use ‘WKT2_2019’ strings, not ‘PROJ’ strings. ‘Windows’ and ‘macOS’ binaries including ‘GDAL’, ‘PROJ’ and their dependencies are provided on ‘CRAN’.
