Twitter will be fixing the previously mentioned error in their GeoJSON X/Y ordering in version 2 of the Twitter API. → この「Twitter API の version 2」って、いつ出るんだろうね
You will notice that this is in Latitude/Longitude order whereas the GeoJSON specification clearly states Longitude/Latitude. → Twitter では [緯度, 経度]、GeoJSON では [経度, 緯度] と順序が逆なので注意
