Saves a subset of the National Seamless database or other
nhdplusTools compatible data based on a specified collection of COMIDs.
This function uses get_nhdplus for the "download" data
source but returns data consistent with local data subsets in a subset
file.
subset_nhdplus(
comids = NULL,
output_file = NULL,
nhdplus_data = NULL,
bbox = NULL,
simplified = TRUE,
overwrite = FALSE,
return_data = TRUE,
status = TRUE,
flowline_only = NULL,
streamorder = NULL,
out_prj = 4269
)Arguments
- comids
integer vector of COMIDs to include.
- output_file
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 database, a subset of NHDPlusHR, or "download" to use a web service to download NHDPlusV2.1 data. Not required if
nhdplus_pathhas been set or the default has been adopted. See details for more.- bbox
object of class "bbox" as returned by sf::st_bbox in Latitude/Longitude. If no CRS is present, will be assumed to be in WGS84 Latitude Longitude.
- simplified
boolean if TRUE (the default) the CatchmentSP layer will be included. Not relevant to the "download" option or NHDPlusHR data.
- overwrite
boolean should the output file be overwritten
- return_data
boolean if FALSE path to output file is returned silently otherwise data is returned in a list.
- status
boolean should the function print status messages
- flowline_only
boolean WARNING: experimental if TRUE only the flowline network and attributes will be returned
- streamorder
integer only streams of order greater than or equal will be downloaded. Not implemented for local data.
- out_prj
character override the default output CRS of NAD83 lat/lon (EPSG:4269)
Value
character path to the saved subset geopackage
Details
This function relies on the National Seamless Geodatabase or Geopackage. It can be downloaded here.
The "download" option of this function should be considered preliminary and subject to revision. It does not include as many layers and may not be available permanently.
