I'm working on the National Weather Service's Twitter Storm Report Project. We are pulling tweets with our search hash tag and plotting them on a map. We had been using an atom search to get the geocoded lat lon pairs, but about three days ago all the tweets started coming in with geo=null. It appears the same for the json calls. So what has changed and what is the best way to get the location information from the geotagged tweets. Thanks for your help.
