Get area 311 service requests from Open Baltimore

Description

Get 311 service requests for a specific area. Service requests from 2017 to 2020 area available but only a single year can be requested at a time. Duplicate requests are removed from the returned data. Requests can be filtered by request type, responsible city agency, or both. You can return multiple types or agencies, by using a custom where query parameter or by calling each type/agency separately.

Usage

get_area_requests(
  area = NULL,
  year = 2022,
  date_range = NULL,
  request_type = NULL,
  agency = NULL,
  where = NULL,
  dist = NULL,
  diag_ratio = NULL,
  unit = "m",
  asp = NULL,
  trim = FALSE,
  geometry = TRUE,
  crs = pkgconfig::get_config("mapbaltimore.crs", 2804),
  duplicates = FALSE,
  ...
)

Arguments

area	sf, sfc, or bbox object. If multiple areas are provided, they are unioned into a single sf object using sf::st_union().
year	Year for service requests. Default 2021. 2017 to 2022 supported.
date_range	Date range as character vector in format of c("YYYY-MM-DD", "YYYY-MM-DD"). Minimum and maximum values are used if length is greater than 1.
request_type	Service request type.
agency	City agency responsible for request. Options include "Transportation", "BGE", "Solid Waste", "Housing", "Water Wastewater", "Health", "Call Center", "Finance", "Liquor Board", "Recreation & Parks", "Fire Department", "Parking Authority", and "General Services"
where	string for where condition. This parameter is ignored if a request_type or agency are provided.
dist	buffer distance in units. Optional.
diag_ratio	ratio of diagonal distance of area's bounding box used as buffer distance. e.g. if the diagonal distance is 3000 meters and the "diag_ratio = 0.1" a 300 meter will be used. Ignored when dist is provided.
unit	Units for buffer. Supported options include "meter", "foot", "kilometer", and "mile", "nautical mile" Common abbreviations (e.g. "km" instead of "kilometer") are also supported. Distance in units is converted to units matching GDAL units for x; defaults to "meter"

trim	If TRUE, x is trimmed to y with st_trim().
geometry	Default TRUE. If FALSE, return requests with missing latitude/longitude (for years prior to 2021 only).
crs	Cordinate reference system to return, Default: 4326 for sf_to_df() and NULL for df_to_sf().
duplicates	If TRUE, return 311 service requests marked as "Duplicate". If FALSE, filter duplicate requests out of results.
...	Arguments passed on to esri2sf::esri2sf outFields vector of fields you want to include. default is NULL for all fields. replaceDomainInfo If TRUE, add domain information to the return data frame. Default FALSE.

)

# Get dirty alley service requests for multiple years using purrr::map_dfr()
purrr::list_rbind(

    c(2021, 2020),
    ~ get_area_requests(
      area = area,
      year = .x,
      request_type = "SW-Dirty Alley"
