Resolve DCIDs from Latitude and Longitude via Data Commons — dc_get_dcid_by

Resolves geographic coordinates (provided as latitude and longitude) to Data Commons DCIDs using the geoCoordinate property.

dc_get_dcid_by_coordinates(
  latitude,
  longitude,
  api_key = Sys.getenv("DATACOMMONS_API_KEY"),
  base_url = Sys.getenv("DATACOMMONS_BASE_URL", unset =
    "https://api.datacommons.org/v2/"),
  return_type = "json"
)

Arguments

latitude: A numeric vector of latitude values.
longitude: A numeric vector of longitude values.
api_key: Your Data Commons API key. If not provided, uses the environment variable DATACOMMONS_API_KEY.
base_url: The base URL of the Data Commons API. Defaults to the public endpoint. For custom deployments, must end with /core/api/v2/.
return_type: Return format: either "list" (parsed R object) or "json" (JSON string).

Value

A list or JSON string, depending on return_type.

Examples

if (FALSE) { # dc_has_api_key()
# Get the DCID for a coordinate
dc_get_dcid_by_coordinates(37.42, -122.08)

# Batch query for multiple coordinates
dc_get_dcid_by_coordinates(c(34.05, 40.71), c(-118.25, -74.01))
}
