Walk Score API Call
Description
A function to perform the basic Walk Score API call.
Usage
getWS(x, y, key)Arguments
x |
longitude of query location (numeric) |
y |
latitude of query location (numeric) |
key |
your Walk Score API key (string), see Details below |
Details
Note that the call uses longitude and latitude coordintes and not addresses like the website interface. It is strongly recomended that Google Geolocation is used to convert addresses to coordinates because this is the method used by the Walk Score website, and will result in the same Walk Score as entering the address into the website interface. The function "geoloc" in this package is a tool for using the Google Geolocation API.
