The development of a new geospatial framework for the palaeoanthropological site of the Sterkfontein Caves, Cradle of Humankind, Gauteng, South Africa

Geographical Information Systems (GIS) provide an essential element in modern paleoanthropological inquiry through their ability to integrate a diverse range of data within a multidimensional spatial framework which can be used for data storage, analysis and modeling. One of the challenges of creating such a framework is the integration of legacy and new data (collected with digital technologies) at large sites with a long history of research. The Sterkfontein Caves, located in the Cradle of Humankind, is the richest Australopithecus-bearing locality in the world and has been the focus of intense palaeoanthropological research for the past 80 years. A diverse range of spatial data has been collected over this history and future integrative research necessitates the development of a unified, cohesive 3D GIS framework. In this paper we describe three phases of work undertaken to implement such a framework and discuss the next steps in its development and utilization for spatial analyses.
