Researching Twitter Geo Location

[sammyjld]

• Any geo-tagging parameters in the update will be ignored if geo_enabled for the user is false (this is the default setting for all users, unless the user has enabled geolocation in their settings)

• The number of digits after the decimal separator passed to lat (up to 8) is tracked so that when the lat is returned in a status object it will have the same number of digits after the decimal separator. Use a decimal point as the separator (and not a decimal comma) for the latitude and the longitude - usage of a decimal comma will cause the geo-tagged portion of the status update to be dropped.

• For JSON, the response mostly uses conventions described in GeoJSON. However, the geo object coordinates that Twitter renders are reversed from the GeoJSON specification.

• GeoJSON specifies a longitude then a latitude, whereas Twitter represents it as a latitude then a longitude: "geo": { "type":"Point", "coordinates":[37.78217, -122.40062] }

• The coordinates object is replacing the geo object (no deprecation date has been set for the geo object yet) – the difference is that the coordinates object, in JSON, is now rendered correctly in GeoJSON.

• If a place_id is passed into the status update, then that place will be attached to the status. If no place_id was explicitly provided, but latitude and longitude are, the API attempts to implicitly provide a place by calling geo/reverse_geocode.

• Users have the ability to remove all geotags from all their Tweets en masse via the user settings page. Currently there is no method to remove geotags from individual Tweets.

• "Places" are specific, named locations with corresponding geo coordinates.

They can be attached to Tweets by specifying a place_id when tweeting.

Tweets associated with places are not necessarily issued from that location but could also potentially be about that location. Places can be searched for. Tweets can also be found by place_id.
