[JAVA] Save Twitter's tweets with Geo in CSV and plot them on Google Map.

For the time being, I don't know how to narrow down the locale from the STREAMING API due to lack of knowledge. So I usually use Search to pick up "Nau" and "i'm at" and plot them.

1. 1. Create CSV data with the previously created Python script for Twitter search
2. Map display in Javascript using GoogleMap API
3. 3. Plot there

I did it like that.

for tweet in tweets["statuses"]:
	User = (tweet["user"]["screen_name"].encode("utf-8"))
		try:
			Place = (tweet["place"]["bounding_box"]["coordinates"])
					
			flat_list = []
			for e in Place:
				flat_list.extend(e)
    	
			flat_list2 = []
			for b in flat_list:
				flat_list2.extend(b)
 
			flat_list3 = []
			for c in flat_list:
				flat_list3.extend(c)
    	
			geolng = flat_list3[0]
			geolat = flat_list3[1]
		except:
			pass

Well, like this, let's open only Place with try.

Place = (tweet["place"]["bounding_box"]["coordinates"])

If you fetch it with, the list will be nested, so use flat_list to cancel the nesting. No, it's not really beautiful ...

Export the acquired data as CSV and plot it on a map.

As expected, there are many metropolitan areas. Do local people not tweet with a lot of positions, or is the Twitter population itself small?

Oh, is the keyword to narrow down useless?
