Download the seamless Reach File (RF1) Database — download

This function downloads and decompresses staged RF1 data. See: https://water.usgs.gov/GIS/metadata/usgswrd/XML/erf1_2.xml for metadata.

The archive is roughly 46 MB and the server is slow, so this function has no example. Pass any writable directory as outdir; the gzipped e00 is downloaded there, decompressed in place, and the path to the e00 returned:


download_rf1(file.path(tempdir(), "rf1"))

download_rf1(
  outdir,
  url = "https://water.usgs.gov/GIS/dsdl/erf1_2.e00.gz",
  progress = TRUE
)

Arguments

outdir: The folder path where data should be downloaded and extracted
url: the location of the online resource
progress: boolean display download progress?

Value

character path to the local e00 file
