In mikejohnson51/HydroData: HydroData

Description

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

Usage

findNWIS(AOI = NULL, siteType = "ST", paramCode = "00060",
  startDate = NULL, endDate = NULL, active = TRUE, full = 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
