dist_calc

numeric; the longitude (degrees) of location 1.

long1

numeric; the latitude (degrees) of location 1.

lat1

numeric; the longitude (degrees) of location 2.

long2

numeric; the latitude (degrees) of location 2.

lat2

character string; must be either "metric" (the default) or "imperial".
Specifying "metric" will return the distance between location 1 and location in kilometers,
whereas "imperial" returns the distance in miles.

units


A simple distance calculator for two sets of geo coordinates.
This function may be utilized to estimate the "straight line" distance between
two sets of, e.g., Google Web Mercator/WGS 84 geocoordinates.


The main functions in this package are drive_time
(used for calculating distances between physical addresses or coordinates) and
geocode_url (used for estimating the lat/long coordinates
of a physical address). Optionally, it generates the cryptographic signatures necessary
for making API calls with a Google for Work/Premium account within the geocoding process.
These accounts have larger quota limits than the "standard_api" and, thus, this package
may be useful for individuals seeking to submit large batch jobs within R to the Google Maps API.
Placement also provides methods for accessing the standard API using a (free) Google API key
(see: <https://developers.google.com/maps/documentation/javascript/get-api-key#get-an-api-key>).
