Twitter的地理標記

我試圖用Twitter的地理標記

curl --user xx:xx -X POST -d 'locations=-0.651,51.208,0.425,51.781' https://stream.twitter.com/1.1/statuses/filter.json > twitter.london.json

我得到那些遙遠的鳴叫下載來自倫敦地區的鳴叫。例如在（-6.71658144,50.48812681）。這是爲什麼？

的鳴叫：

根據Twitter的文檔中，位置參數接受逗號分隔經度的列表，緯度對指定一組的包圍盒。

如果您只傳入一個經緯度，那麼它會將最近的推文返回到該位置。你是否還指定了一個過濾器查詢，如果是的話，這將大大減少返回的Tweets數量，這意味着離倫敦最近的Tweet，實際上是數英里之遙。我有類似的問題。如上所述，我只是試過了，如果你使用下面的緯度和經度，沒有其他過濾器查詢它的效果很好。

{locations: [51.50,0.12,51.75,1.25]}

還有一點要注意，是不是有很多的鳴叫的實際附上的位置了，而且往往裏面做的那些非常不準確的，因爲它們實際上可以從指定的作者歸屬位置來自己個人資料。
