Stage NHDPlus National Data (deprecated) — stage_national

Breaks down the national geo database into a collection of quick to access R binary files.

stage_national_data(
  include = c("attribute", "flowline", "catchment"),
  output_path = NULL,
  nhdplus_data = NULL,
  simplified = TRUE
)

Arguments

include: character vector containing one or more of: "attributes", "flowline", "catchment".
output_path: character path to save the output to defaults to the directory of the nhdplus_data.
nhdplus_data: character path to the .gpkg or .gdb containing the national seamless dataset. Not required if nhdplus_path has been set.
simplified: boolean if TRUE (the default) the CatchmentSP layer will be included.

Value

list containing paths to the .rds files.

Details

"attributes" will save `NHDFlowline_Network` attributes as a separate data.frame without the geometry. The others will save the `NHDFlowline_Network` and `Catchment` or `CatchmentSP` (per the `simplified` parameter) as sf data.frames with superfluous Z information dropped.

The returned list of paths is also added to the nhdplusTools_env as "national_data".
