Get selected area streets

Description

Get streets within an area or areas.

Usage

get_area_streets(
  area = NULL,
  street_type = NULL,
  sha_class = NULL,
  bbox = NULL,
  dist = NULL,
  diag_ratio = NULL,
  asp = NULL,
  trim = FALSE,
  msa = FALSE,
  union = TRUE
)

Arguments

`area`	sf object with area of streets to return.
`street_type`	selected street subtypes to include. By default, the returned data includes all subtypes except alleys ("STRALY"). Options include c("STRALY", "STRPRD", "STRR", "STREX", "STRFIC", "STRNDR", "STRURD", "STCLN", "STRTN")
`sha_class`	selected SHA classifications to include. "all" selects all streets with an assigned SHA classification (around one-quarter of all street segments). Additional options include c("COLL", "LOC", "MART", "PART", "FWY", "INT")
`bbox`	`bbox` object defining area used to filter data. If an area is provided, the bounding box is ignored.
`dist`	buffer distance in meters. Optional.
`diag_ratio`	ratio to set map extent based diagonal distance of area's bounding box. Ignored when `dist` is provided.
`asp`	Aspect ratio of width to height as a numeric value (e.g. 0.33) or character (e.g. "1:3").
`trim`	Logical. Default `FALSE`. Trim streets to area using `sf::st_intersection()`.
`msa`	Logical. Default `FALSE`. Get streets from cached `baltimore_msa_streets.gpkg` file using `cachedata` parameter of `get_area_data` function.
`union`	Logical. Default `TRUE`. Union geometry based on `fullname` of streets.
