This paper outlines the ways in which information technologies (ITs) were used in the Haiti relief effort, especially with respect to web‐based mapping services. Although there were numerous ways in which this took place, this paper focuses on four in particular: CrisisCamp Haiti, OpenStreetMap, Ushahidi, and GeoCommons. This analysis demonstrates that ITs were a key means through which individuals could make a tangible difference in the work of relief and aid agencies without actually being physically present in Haiti. While not without problems, this effort nevertheless represents a remarkable example of the power and crowdsourced online mapping and the potential for new avenues of interaction between physically distant places that vary tremendously.

This article presents an overview and initial results of a geoweb analysis designed to provide the foundation for a continued discussion of the potential impacts of 'big data' for the practice of critical human geography. While Haklay's (2012) observation that social media content is generated by a small number of 'outliers' is correct, we explore alternative methods and conceptual frameworks that might allow for one to overcome the limitations of previous analyses of user-generated geographic information. Though more illustrative than explanatory, the results of our analysis suggest a cautious approach toward the use of the geoweb and big data that are as mindful of their shortcomings as their potential.More specifically, we propose five extensions to the typical practice of mapping georeferenced data that we call going 'beyond the geotag': (1) going beyond social media that is explicitly geographic; (2) going beyond spatialities of the 'here and now'; (3) going beyond the proximate; (4) going beyond the human to data produced by bots and automated systems, and (5) going beyond the geoweb itself, by leveraging these sources against ancillary data, such as news reports and census data. We see these extensions of existing methodologies as providing the potential for overcoming existing limitations on the analysis of the geoweb.The principal case study focuses on the widely reported riots following the University of Kentucky men's basketball team's victory in the 2012 NCAA championship and its manifestation within the geoweb. Drawing upon a database of archived Twitter activity -including all geotagged tweets since December 2011-we analyze the geography of tweets that used a specific hashtag (#LexingtonPoliceScanner) in order to demonstrate the potential application of our methodological and conceptual program. By tracking the social, spatial, and temporal diffusion of this hashtag, we show how large databases of such spatially referenced internet content can be used in a more systematic way for critical social and spatial analysis.

As digital social data have become increasingly ubiquitous, many have turned their attention to harnessing these massive data sets in order to produce purportedly more accurate and complete understandings of social processes. This intervention addresses the relationships between geography and big data and their intertwined futures. We focus on the impacts of an age of big data on the discipline of geography and geographic thought and methodology, as well as how geography might provide a useful lens through which to understand big data as a social phenomenon in its own right. Ultimately, we see significant potential in big data, but remain skeptical of the prevalent discourses around it, as they tend to obscure, more than reveal, the complexity of social and spatial processes.
