Set up Earthdata Login (EDL) credentials using a .netrc file

Source: R/edl_netrc.R
edl_netrc.Rd

This function creates a .netrc file with Earthdata Login (EDL) credentials (username and password) and sets the necessary environment variables for GDAL to use the .netrc file.

Usage

edl_netrc(
  username = default("user"),
  password = default("password"),
  netrc_path = edl_netrc_path(),
  cookie_path = edl_cookie_path(),
  cloud_config = TRUE
)

Arguments

username

EarthData Login User

password

EarthData Login Password

netrc_path

Path to the .netrc file to be created. Defaults to the appropriate R package configuration location given by tools::R_user_dir().

cookie_path

Path to the file where cookies will be stored. Defaults to the appropriate R package configuration location given by tools::R_user_dir().

cloud_config

set gdal_cloud_config() env vars as well? logical, default TRUE.

Value

TRUE invisibly if successful

Details

The function sets the environment variables GDAL_HTTP_NETRC and GDAL_HTTP_NETRC_FILE to enable GDAL to use the .netrc file for EDL authentication. GDAL_HTTP_COOKIEFILE and GDAL_HTTP_COOKIEJAR are also set to allow the authentication to store and read access cookies.

Additionally, it manages the creation of a symbolic link to the .netrc file if GDAL version is less than 3.7.0 (and thus does not support GDAL_HTTP_NETRC_FILE location).

Examples

if (FALSE) { # interactive()

edl_netrc()
url <- lpdacc_example_url()
terra::rast(url, vsi=TRUE)
}
