How can we get tweets from specific country

I've read a lot about this part and what I found is to write the geocode and search for tweets for example https://api.twitter.com/1.1/search/tweets.json?geocode=37.781157,-122.398720,1mi&count=10

according to what i found in twitter website Returns tweets by users located within a given radius of the given latitude/longitude. A maximum of 1,000 distinct "sub-regions" will be considered when using the radius modifier. Example Values: 37.781157,-122.398720,1mi

The question!, how can we define or draw the latitude and longitude ? I've tried google map but I only get a point then i can add the miles around this point, but this is not enough, I want the whole country to be included, is that possible?

Solution

One way is to use twitter geo search API, get the place id and then perform regular search using place:place_id. Example, using tweepy:

import tweepy

auth = tweepy.OAuthHandler(..., ...)
auth.set_access_token(..., ...)

api = tweepy.API(auth)
places = api.geo_search(query="USA", granularity="country")
place_id = places[0].id

tweets = api.search(q="place:%s" % place_id)
for tweet in tweets:
    print tweet.text + " | " + tweet.place.name if tweet.place else "Undefined place"

Also see these threads:

UPD (the same example using python-twitter):

from twitter import *


t = Twitter(auth=OAuth(..., ..., ..., ...))

result = t.geo.search(query="USA", granularity="country")
place_id = result['result']['places'][0]['id']

result = t.search.tweets(q="place:%s" % place_id)
for tweet in result['statuses']:
    print tweet['text'] + " | " + tweet['place']['name'] if tweet['place'] else "Undefined place"

Hope that helps.
