get_geoconnex_reference {nhdplusTools}

get geoconnex reference feature layers

Description

Queries the geoconnex reference feature server for features of interest.

Usage

get_geoconnex_reference(
  AOI,
  type = NULL,
  t_srs = NULL,
  buffer = 0.5,
  status = TRUE
)

Arguments

AOI

bbox, sf polygon or point, or a URL that will return an sf object when passed to read_sf

type

character the feature type chosen from discover_geoconnex_reference

t_srs

character (PROJ string or EPSG code) or numeric (EPSG code). A user specified - target -Spatial Reference System (SRS/CRS) for returned objects. Will default to the CRS of the input AOI if provided, and to 4326 for ID requests.

buffer

numeric. The amount (in meters) to buffer a POINT AOI by for an extended search. Default = 0.5

status

boolean print status or not

Value

sf data.frame containing requested reference features

Examples

dplyr::distinct(discover_geoconnex_reference()[c("id", "title")])

AOI <- sf::st_as_sfc(sf::st_bbox(c(xmin = -89.56684, ymin = 42.99816,
                                   xmax = -89.24681, ymax = 43.17192),
                                 crs = "+proj=longlat +datum=WGS84 +no_defs"))

get_geoconnex_reference(AOI, type = "hu04")

get_geoconnex_reference("https://geoconnex.us/ref/mainstems/315626", type = "hu04", )

AOI <- sf::st_sfc(sf::st_point(c(-89.56684, 42.99816)),
                  crs = "+proj=longlat +datum=WGS84 +no_defs")
