location_getOpenCageInfo: Get location information from OpenCage

In MazamaLocationUtils: Manage Spatial Metadata for Known Locations

Get location information from OpenCage

Description

The OpenCage reverse geocoding service is used to obtain all available information for a specific location.

The data from OpenCage should be considered to be the gold standard for address information could and should be used to override information we get elsewhere.

Usage

location_getOpenCageInfo(longitude = NULL, latitude = NULL, verbose = FALSE)

Arguments

longitude	Single longitude in decimal degrees E.
latitude	Single latitude in decimal degrees N.
verbose	Logical controlling the generation of progress messages.

Value

Single-row tibble with OpenCage information.

Note

The OpenCage service requires an API key which can be obtained from their web site. This API key must be set as an environment variable with:

Sys.setenv("OPENCAGE_KEY" = "YOUR_PERSONAL_API_KEY")

The OpenCage "free trial" level allows for 1 request/sec and a maximum of 2500 requests per day.
