Get intersections

Source: R/get_intersection.R
get_intersection.Rd

Get intersections by name and id with option to apply buffer and return streets or edgement of pavement instead of the intersection.

Usage

get_intersection(
  street_names = NULL,
  id = NULL,
  dist = 25,
  type = c("area", "edge_of_pavement", "streets"),
  trim = TRUE
)

Arguments

street_names

street names matching one or more of the names from the named_intersections data.

id

id values corresponding to one or more id values from the named_intersections data.

dist

buffer distance in meters. Optional.

type

Type of data to return. "area" returns the intersection center if dist is 0 or a circle centered on the intersection center with any positive dist value. "edge_of_pavement" or "streets" return what either the cached edge of pavement data or street center line data.

trim

If type is "edge_of_pavement" or "streets" and trim is TRUE return data trimmed to the buffered intersection, otherwise return data within bounding box, Default: TRUE

Value

Intersection center point, buffered area around intersection center, streets, or edge of pavement data.
