Find USGS NWIS Stream Gages

Source: R/findNWIS.R

findNWIS returns a SpatialPointsDataFrame of all USGS NWIS gages for an Area of Interest. This dataset is accessed through the NWIS web portal and contains the following attributes:

  • 'OBJECTID' : character Unique ID in dataset

  • 'feature_id' : character NHD COMID for reach

  • 'site_no': character NWIS ID number

  • 'site_name' : character Name of site

  • 'da_sqkm' : character Area drainign to gage in square kilometers

  • 'lat_reachCent' : numeric Latitude of the reach center, decimil degrees

  • 'lon_reachCent' : numeric Longitude of the reach center, decimil degrees


findNWIS(AOI = NULL, ids = FALSE, comids = FALSE)

Arguments

AOI

A Spatial* or simple features geometry, can be piped from getAOI
ids

If TRUE, a vector of NIWS gage IDs are added to retuned list (default = FALSE)
comids

f TRUE, a vector of NHD COMIDs IDs are added to retuned list (default = FALSE)

Value

a list() of minimum length 2: AOI and nwis

Examples

# NOT RUN {
co = getAOI(state = "CO") %>% findNWIS()
# }
