sign

configure for automatic Planetary Computer signing by GDAL

driver

character vector of appropriate GDAL driver name

Value

character vector

Examples

vsicurl("https://netcdf-r-us.org/f.nc")
#> [1] "/vsicurl/https://netcdf-r-us.org/f.nc"

driver("somefile.h5", "HDF5")
#> [1] "HDF5:somefile.h5"

unvsicurl("/vsicurl/https://netcdf-r-us.org/f.nc")
#> [1] "https://netcdf-r-us.org/f.nc"

unprefix("NETCDF:/u/user/somefile.nc")
#> [1] "/u/user/somefile.nc"

## MPC signing
mpc <- "https://sentinel2l2a01.blob.core.windows.net/sentinel2-l2/.../T43DFE_B04_10m.tif"
vsicurl(mpc , sign = TRUE)
#> [1] "/vsicurl?pc_url_signing=yes&url=https://sentinel2l2a01.blob.core.windows.net/sentinel2-l2/.../T43DFE_B04_10m.tif"
