Get nearby geotagged tweets


I’m working on a project that gets the user’s location and shows nearby geotagged tweets on a map, and uses language analysis to show the overall mood of an area. So far I’ve encountered one big issue, that’s that the vast majority of tweets retreived with the API (using the location radius) are not actually geotagged, so can’t be plotted. I know you can do it with streaming, but I’ve got no idea how to!

Any help would be great, thanks!
