Examining Land-Use through GIS-Based Kernel Density Estimation: A Re-Evaluation of Legacy Data from the Berbati-Limnes Survey

ORCID Icon, ORCID Icon & ORCID Icon
 

ABSTRACT

The use of archaeological survey data for evaluation of landscape dynamics has commonly been concerned with the distribution of settlements and changes in number of recorded sites over time. Here we present a new quantitative approach to survey-based legacy data, which allows further assessments of the spatial configuration of possible land-use areas. Utilizing data from an intensive archaeological survey in the Berbati-Limnes area, Greece, we demonstrate how GIS-based kernel density estimations (KDE) can be used to produce cluster-based density surfaces that may be linked to past land-use strategies. By relating density surfaces to elevation and slope, it is also possible to quantify shifts in the use of specific environments on a regional scale, allowing us to model and visualize land-use dynamics over time. In this respect, the approach provides more multifaceted information to be drawn from archaeological legacy data, providing an extended platform for research on human-environment interactions.

Acknowledgments

The methods of GIS-based KDE described in the current study was developed and carried out within the framework of the Domesticated Landscapes of the Peloponnese (DoLP) Project hosted at the Department at Archaeology and Ancient History, Uppsala University and generously funded by the Swedish Research Council (Grant #421-2014-1181). The project has an interdisciplinary scope and the aim is to investigate long-term human-environment interactions in the Peloponnese, from the Neolithic until the 4th century a.d. The initial plotting of georeferenced site data was originally carried out by Emanuel Savini within the framework of the 1999 Mastos Survey directed by Berit Wells. We are also grateful towards the Greek National Cadastre and Mapping Agency, Ktimatologio, for providing us with high resolution DEM data of the Peloponnese (Copyright © 2012 NATIONAL CADASTRE & MAPPING AGENCY S. A.). We are further grateful for the comments provided by the three anonymous reviewers, who provided good input for improving the original manuscript. Any mistakes or idiosyncrasies remain our own.
