Grounded visualization: integrating the analysis of qualitative and quantitative data through grounded theory and visualization

Our purpose in this paper is to conceptualize and demonstrate an integrated analytical method for using both qualitative and quantitative data through geographic information systems (GIS) and ethnography. We acknowledge that the use of both types of data has been possible in GIS for some time, particularly for representation purposes. However, a recursive integration of different forms of data at the analysis level has been less explored and minimally theorized. Drawing on recent work in critical GIS and feminist perspectives, we suggest that visualization offers a strong technique for this effort but we approach it from the analytical base of grounded theory. Thus, we present an example of how grounded theory and visualization might be used together to construct an integrated analysis strategy that is both iterative and reflexive, both contextual and conceptual. We use Knigge’s work on community gardens in Buffalo, New York, to provide a substantive example of the proposed methods.

Revisiting Critical GIS

The article looks into the critical geographic information science (GIS) in approaching questions both emerging and enduring around the intersection of the spatial and the digital. It offers trading zones for discussion of issues, for building alliances and interrogating tensions, and for a constant dialectical process of critique and renewal. One tension running through critical GIS is the contradictory role it has played in addressing questions of social justice
