Cover ImageWe recently contributed a chapter to “Big Data: Techniques and Technologies in Geoinformatics” entitled “Geoinformatics and Social Media: A New Big Data Challenge” where we explore how social media and ambient geographic information is transforming geoinformatics. We discuss the key characteristics of big geosocial data beofre moving onto geosocial complexity.  Specifically how goeosocial data is predominantly linked information; links are established among users to establish a social network and among words to define a storyline that is communicated through pieces of information. Aggregating all these connections (links) provides us with a view of the users as a structured, networked community that can be represented as a graph. We then turn to modeling and analyzing geosocial multimedia before concluding with an outlook pertaining to the grand challenges and opportunities for big geosocial data.

Demarcating New Boundaries: Mapping Virtual Polycentric Communities through Social Media Content

The proliferation of social media has led to the emergence of a new type of geospatial information that defies the conventions of authoritative or volunteered geographic information, yet can be harvested to reveal unique and dynamic information about people and their activities.
