link_to_waterbodies: Link geopoints to Waterbodies

In hydrolinks: Hydrologic Network Linking Data and Tools

Description

Link geopoints to waterbodies in a geospatial dataset. Use the point-in-polygon technique with user-selectable polygon buffer size.

Usage

link_to_waterbodies(lats, lons, ids, dataset = c("nhdh", "hydrolakes",
  "nhdplusv2"), buffer = 0)

Arguments

lats	Vector of point latitudes
lons	Vector of point longitudes
ids	Vector of point identifiers (string or numeric)
dataset	Character name of dataset to link against. Can be either "nhdh", "hydrolakes", or "nhdplusv2"
buffer	Numeric width of polygon buffer in m

Value

Water body permanent IDs

Examples

latlon = c(43.108728, -89.418293)
## Not run: 
#returns linked waterbody site information for that lat/lon
link_to_waterbodies(latlon[1], latlon[2], 'id1', dataset = 'nhdh')


## End(Not run)
