This case study presents the early stages of a deep mapping initiative in Charleston, South Carolina (USA). A foundational landscape for exploring the socioeconomic and political structures in the United States from the late 17th century to the present, the evidence for Charleston’s history is held in a variety of repositories, local and state agencies, and information curated by local communities and organizations. This rich resource mosaic creates an environment rich in information but complicated by varying levels of accessibility. The “Spatial History of Charleston” (SHOC) is a long-term mapping initiative that collates historical information about the Charleston area within a spatial and temporal framework. Within this endeavor lie interconnected issues related to scale, access, ownership, agency, and agenda. Employing a community-centered approach, SHOC seeks to navigate concerns about access, agency, ownership, and agenda, establishing a platform that increases access to data about and by communities, thereby democratizing information and facilitating integration and synthesis.
