Title: | Search for POIs using ArcGIS 'Places Service' |
---|---|
Description: | The ArcGIS 'Places service' is a ready-to-use location service that can search for businesses and geographic locations around the world. It allows you to find, locate, and discover detailed information about each place. Query for places near a point, within a bounding box, filter based on categories, or provide search text. 'arcgisplaces' integrates with 'sf' for out of the box compatibility with other spatial libraries. Learn more in the 'Places service' API reference <https://developers.arcgis.com/rest/places/>. |

A category describes a type of place, such as "movie theater" or "zoo". The places service has over 1,000 categories (or types) of place. The categories fall into ten general groups: Arts and Entertainment, Business and Professional Services, Community and Government, Dining and Drinking, Events, Health and Medicine, Landmarks and Outdoors, Retail, Sports and Recreation, and Travel and Transportation.
categories( search_text = NULL, icon = NULL, language = NULL, token = arc_token() )
categories( search_text = NULL, icon = NULL, language = NULL, token = arc_token() )
search_text |
Default |
icon |

language |
Optional case-sensitive parameter to specify the preferred language to. |
token |
an object of class |
The categories are organized into a hierarchical system where a general category contains many more detailed variations on the parent category. For example: "Travel and Transportation" (Level 1), "Transport Hub" (Level 2), "Airport" (Level 3) and "Airport Terminal" (Level 4). The hierarchy has up to 5 levels of categories.
A data.frame
with columns:
category_id
: the unique identifier for the category
full_label
: a list of character vectors containing all labels for the category
icon_url
: a character vector containing the icon URL if present
parents
: a list of character vectors containing the parent category_id
values
## Not run: categories("Coffee Shop") ## End(Not run)
## Not run: categories("Coffee Shop") ## End(Not run)
The /categories/{categoryId}
request returns all the groups to which the category belongs. You must supply a category ID to use this request. Note: Query parameters are case-sensitive.
category_details( category_id, icon = NULL, language = NULL, token = arc_token(), .progress = TRUE )
category_details( category_id, icon = NULL, language = NULL, token = arc_token(), .progress = TRUE )

The language codes use the CLDR (Common Locale Data Repository) format string that uses a two letter language code (e.g. "fr" for French) optionally followed by a two letter country code (e.g. "fr-CA" for French in Canada).
If an unsupported language code is used, then the service will attempt to fall-back to the closest available language. This is done by stripping regional and extension subtags to find a known language code. For example, French Canadian (fr-CA) is unsupported so this falls back to French fr.
Should the fallback fail, then the service will return category names in the default language en for English.

Finds places that are within a given radius of a specified location. The returned places contain basic data such as name, category and location.

An sf
object with columns
place_id
: The unique Id of this place. The ID can be passed to place_details()
to retrieve additional details.
name
: The name of the place, or point of interest. You can search for places by name using the searchText property
distance
: A double vector of the distance, in meters, from the place to the search point.
categories
: A data.frame
with two columns category_id
and label
. Categories are uniquely identified by a categoryId. For example, 17119
identifies a "Bicycle Store" and 10051
identifies a "Stadium". Note that a single place can belong to multiple categories (for example, a petrol station could also have a super-market).
icon
: A character vector of the URL for an icon for this place or category in either svg, cim or png format.
geometry
: an sfc_POINT
object in EPSG:4326

The /places/{placeId}
request returns details for a place.
place_details( place_id, requested_fields, icon = NULL, token = arc_token(), .progress = TRUE )
place_details( place_id, requested_fields, icon = NULL, token = arc_token(), .progress = TRUE )

To request details, you use the requested_fields
argument to specify the fields and the attributes you want from the Place, Address, Details and/or Location price groups.
It is always recommended to specify the fields you want, however, you can also use requested_fields=all
to return all of the attributes available. By default, The place_id
attribute is always returned in addition to the other attributes you requested.
The attributes available for places may vary. For example, opening hours may not be available (or applicable) for geographic places or landmarks.
You will only be charged for attributes that contain valid values for the requested fields. If no data is available for the requested field, null or an empty collection is returned and you are not charged. You are only charged once if one or more attributes with valid values are returned from a price group.

The /places/within-extent
request searches for places within an extent (bounding box).
within_extent( xmin, ymin, xmax, ymax, search_text = NULL, category_id = NULL, icon = NULL, token = arc_token() )
within_extent( xmin, ymin, xmax, ymax, search_text = NULL, category_id = NULL, icon = NULL, token = arc_token() )
xmin |

You must supply the xmin
, ymin
, xmax
and ymax
coordinates to define the extent. The maximum width and height of an extent that can be used in a search is 20,000 meters.
You can also provide multiple categories or search text to find specific types of places within the extent.
Note: You cannot permanently store places. Please see the Terms of use.
Note: Query parameters are case-sensitive.
