I used twitter's REST API to get few thousands tweets from last two days. Everything went ok, but when I put tweets on the map, there is empty "box-like" area (no tweets for almost entire Europe - look at 1st picture).
Last week I used REST API to get data from around India and everything were ok (look at 2nd picture).
I used GET search/tweets with geocode parameter:
" Returns tweets by users located within a given radius of the given latitude/longitude. The location is preferentially taking from the Geotagging API, but will fall back to their Twitter profile. The parameter value is specified by “latitude,longitude,radius”, where radius units must be specified as either “mi” (miles) or “km” (kilometers). Note that you cannot use the near operator via the API to geocode arbitrary locations; however you can use this geocode parameter to search near geocodes directly. A maximum of 1,000 distinct “sub-regions” will be considered when using the radius modifier.
Example Values: 37.781157,-122.398720,1mi "
Anyone seen this problem? Any clue?
In my case I used central point around like this "20.0,50.0,2500mi"
