GDALDriver objects encapsulate GDAL file format
GDALDriver inherits from
getGDALDriverNames() gdalDrivers() getDriverName(driver) getDriverLongName(driver) getGDALVersionInfo(str = "--version") getGDALCheckVersion() getGDALwithGEOS() rgdal_extSoftVersion() getCPLConfigOption(ConfigOption) setCPLConfigOption(ConfigOption, value) get_cached_orig_PROJ_LIB() get_cached_orig_GDAL_DATA() get_cached_set_PROJ_LIB() get_cached_set_GDAL_DATA()
An object inheriting from class 'GDALDriver'
A string, may be one of
CPL configure option documented in https://trac.osgeo.org/gdal/wiki/ConfigOptions and elsewhere in GDAL source code
a string value to set a CPL option; NULL is used to unset the CPL option
returns all driver names currently installed in GDAL, with their declared create and copy status (some drivers can create datasets, others can only copy from a prototype with a different driver.
returns the GDAL driver name associated with the driver object.
returns a longer driver name.
returns the version of the GDAL runtime shared object.
checks the version of the GDAL headers used when building the package (GDAL_VERSION_MAJOR, GDAL_VERSION_MINOR) - if the two versions differ, problems may arise (the C++ API/ABI may have changed), and rgdal should be re-installed
because drivers may behave differently if GDAL itself was built with GEOS support, the function uses a heuristic to check whether GDAL has access to the GEOS Union function or not
The values of environment variables PROJ_LIB and GDAL_DATA as read when this package was loaded
"", the values set when loading this package to point to metadata files included in CRAN binary packages
Objects can be created by calls of the form
new("GDALDriver", name, handle), where name: a string giving the name of a GDAL driver, handle: used internally; not for public consumption (default = NULL).
Object of class
"externalptr", from class "GDALMajorObject", used internally; not for public consumption
signature(.Object = "GDALDriver"): drivername: a string giving the name of a GDAL driver, handle: used internally; not for public consumption (default = NULL)
Loading the rgdal package changes the
GDAL_DATA environmental variable to the GDAL support files bundled with the package.
