These functions allow more direct access to some of the rgdal C API. These are advanced methods intended for package developers only.
GDALcall(object, option, ...)
rawTransform(projfrom, projto, n, x, y, z=NULL, wkt=FALSE)
GDALcall does not return anything. rawTransform returns a matrix of transformed coordinates.
GDALTransientDataset (option = 'SetGeoTransform', 'SetProject') or GDALRasterBand (the other options)
character. One of 'SetGeoTransform', 'SetProject', 'SetNoDataValue', 'SetStatistics', 'SetRasterColorTable' or 'SetCategoryNames')
additional arguments. The values to be set
character. PROJ.4 coordinate reference system (CRS) description
character. PROJ.4 CRS description
number of coordinates
x coordinates
y coordinates
z coordinates
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
