Unveiling Site Visibility: A Study of Farming Communities in the Magaliesberg Region, South Africa

This paper explores the historical and contemporary significance of visibility in human interactions with their environments, particularly in the context of archaeology and the application of geographic information systems (GIS) for visibility analysis. The study highlights the role of visibility analysis in investigating not only the physical visibility of features in landscapes but also the cultural significance associated with seeing or not seeing them. It draws from the ‘visibility relates’ principle, which argues that individuals tend to establish connections with visible entities. The focus is on comparing nineteenth-century urban settlements (Kaditshwene, Molokwane, and Marothodi) in the Magaliesberg region of South Africa, particularly examining the strategic positioning of kraals within these Sotho-Tswana farming communities. These settlements are some of the more popular Late Farming Communities (AD 1300–1840) in South Africa; hence, they have archaeological background and are among the few, if not the only ones, that have LiDAR data coverage. The findings reveal distinctions in visibility at both settlement and household scalar levels, with Kaditshwene standing out as different from Marothodi and Molokwane. This suggests that kraals were strategically located to be more or less visible based on specific settlement circumstances, such as attracting people from other communities and concerns about cattle theft. This study contributes to GIS approaches to archaeological sites and landscapes in Africa and calls for more extensive use of geospatial statistics in African archaeology.
