Co-Lab is a collaborative faculty initiative in the College of Design @ NC State University that uses mapping as a critical and participatory research tool. Co-Lab’s current publications explore both the theory and application of mapping as a critical research tool, participatory mapping as a dialectical engagement device, and the value of mapping and visualization in fields outside of design, architecture and urban planning. Embedded in this initiative is a new theory of critical placemaking that builds upon the rich heritage of participatory design, placemaking and critical cartography. The value of placemaking underpins a perspective that promotes citizen/community agency and dialectical engagement in design decisions.
