Hey guys, im newbie that trying to create apps using Twitter API. I want to retrieve tweets with specific mention and hashtag, so i’m using https://api.twitter.com/1.1/search/tweets.json. Now i have an issue, i want to retrieve geo location from each tweet ( of course when they activated their geo location).

I am converting the JSON format into array format and i found that the data show type of location is polygon and have some coordinates like this :

[bounding_box] => Array
                            (
                                [type] => Polygon
                                [coordinates] => Array
                                    (
                                        [0] => Array
                                            (
                                                [0] => Array
                                                    (
                                                        [0] => 110.304567
                                                        [1] => -7.773728
                                                    )

                                                [1] => Array
                                                    (
                                                        [0] => 110.38574
                                                        [1] => -7.773728
                                                    )

                                                [2] => Array
                                                    (
                                                        [0] => 110.38574
                                                        [1] => -7.699502
                                                    )

                                                [3] => Array
                                                    (
                                                        [0] => 110.304567
                                                        [1] => -7.699502
                                                    )

                                            )

                                    )

                            )

Which should i choose as tweet’s location from them ?

The location is somewhere inside that polygon. You could use an “average” position by finding the centre of the polygon, or choose one of the corners.
