GDALcall

rawTransform

GDALTransientDataset (option = 'SetGeoTransform', 'SetProject') or GDALRasterBand (the other options)

object

character. One of 'SetGeoTransform', 'SetProject', 'SetNoDataValue', 'SetStatistics', 'SetRasterColorTable' or 'SetCategoryNames')

option

additional arguments. The values to be set

character. PROJ.4 coordinate reference system (CRS) description

projfrom

projto

default FALSE, if TRUE, the caller determines that projfrom and projto are wkt and that new_proj_and_gdal() returns TRUE to avoid multiple warnings when the function is called repetitively

These functions allow more direct access to some of the rgdal C API. These are advanced methods intended for package developers only.

spatial

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'.
