Set the GDAL
warning level or get a data.frame
with the available GDAL drivers (file formats), or, if warn=NA
and drivers=FALSE
, you get the version numbers of one or all of the GDAL, PROJ and GEOS libraries.
GDAL
is the software library that terra builds on to read and write spatial data and for some raster data processing. PROJ
is used for transformation of coordinates ("projection") and GEOS
is used for geometric operations with vector data.

If NA
and drivers=FALSE
, the version of the library specified by lib
is returned. Otherwise, the value should be an integer between 1 and 4 representing the level of GDAL warnings and errors that are passed to R. 1 = warnings and errors; 2 = errors only (recoverable errors as a warning); 3 = irrecoverable errors only; 4 = ignore all errors and warnings. The default setting is 3
