I have seen quite a few ESRI web apps that utilize Geo-Tagged social media posts as a point data layer. I'm wondering how one goes about querying things like Twitter, Flickr and YouTube to return posts related to a specific location. I'm also hoping to be able to filter these results based on hash-tags. Twitter is my main interest, but I know when I get that working I'll have people clamoring for the others.
My hope is to add this to our public web viewer where citizens view pictures, videos and tweets about our public lands.
Also, are these Geo-Tagged posts limited by your own personal followers / friends?
Here is an ESRI example of what I am looking for: ESRI Australia Wildfires Map
