In this era of social media, we witness a huge community involvement in spatial data production. Social media maps assemble information from various sources that are mostly derived from 'crowd-sourced' data. For those not familiar with social media maps, check out ESRI's Hurricane and Cyclone social media map. Social media APIs allow content from social networks like Twitter, Youtube, Flickr, and many more, to be embedded on to your maps. Also, certain social media map applications allow active editing by users. Amidst this crowd-sourcing interaction where there is a huge window of opportunity for inappropriate content intrusion, how do you maintain and automate quality check of such social media maps?
