GoogleRoadDist: Road Distance between two points from Google Maps

In estebanlp/GoogleDataSearch: Dataframe building from Google Maps queries to allow for Spatial Economic Analysis

Description

Returns the road distance and time from Google Maps between two points in space, origin and destination.

Usage

  GoogleRoadDist(orilat,orilon,deslat,deslon,mode,apikey,departure_time,arrival_time,transit_mode,transit_routing_preference)

Arguments

orilat	Latitude coordinate of the origin point in geodesic format. This could be numeric or string.
orilon	Longitude coordinate of the origin point in geodesic format. This could be numeric or string.
deslat	Latitude coordinate of the destination point in geodesic format. This could be numeric or string.
deslon	Longitude coordinate of the destination point in geodesic format. This could be numeric or string.
mode	Travel mode in string format as Google requires it. Possible alternatives are: driving (default): indicates distance calculation using the road network. walking: requests distance calculation for walking via pedestrian paths & sidewalks (where available). bicycling: requests distance calculation for bicycling via bicycle paths & preferred streets (where available). transit: requests distance calculation via public transit routes (where available). This value may only be specified if the request includes an API key or a Google Maps API for Work client ID. If you set the mode to transit you can optionally specify either a departure_time or an arrival_time. If neither time is specified, the departure_time defaults to now (that is, the departure time defaults to the current time). You can also optionally include a transit_mode and/or a transit_routing_preference.
apikey	Your API Key from https://developers.google.com/places/web-service

Value

A list with two numeric elements containing distance in miles and minutes of a trip between two points.
