Find the bounding box coordinates that encompass a city
using the Yahoo! GeoPlanet and PlaceFinder API
Input: locs.txt
A file that contains the cities we are interested in
with each city on a separate line.
The Yahoo! GeoPlanet API we will be using
to gather WOEIDs of cities supports many formats of inputs.
Output: boundbox.txt
A file containing the northeast and southwest latitude and
longitude values for the bounding box of each city.
Each city has its own line with the format:
id cityname NElat NElng SWlat SWlng
Input and output files have already been populated with 50 cities
as an example
This code could potentially also be used, with minor tweaking, to
find bounding box values for entities other than cities, depending
on what else is available on Yahoo! PlaceFinder, such as counties
and neighborhoods.
