Drones Helping Archaeologists Map Caribbean Terrain Difficult To Navigate On Foot


SANTO DOMINGO — Drones are proving to be a good means of mapping man-made changes in the landscape over difficult terrain.

Geophysicist Till Sonneman and his archaeological colleagues are experimenting with drones in the inaccessible areas of the Caribbean.

Columbus as turning point

In the widescale NEXUS1492 research project professor of Caribbean Archaeology Corinne Hofman and her Leiden University team are exploring the cultures and societies of the many indigenous peoples in the Caribbean region around 1500. What was life like in this area before Columbus landed there in 1492, and what happened afterwards?

New techniques

In the course of the research it became apparent that more traditional techniques such as excavations – in some cases with heavy material – and explorations in the field were not able to provide a complete picture.

On the Caribbean island of Hispaniola, for example, dense forests and steep hills make traditional forms of research difficult and expensive. Columbus established the first European settlement there, but where had the original peoples settled, how did they live and how did the interaction with Europeans turn out?

Organised communities

To supplement traditional archaeological methods, Till Sonneman and his colleagues developed more advanced techniques of surveying areas using drones. These drones provide photos and measurements (“photogrammetrical models”) on the basis of which maps can be drawn.

On these maps Sonnemann and his colleagues saw man-made interruptions to the natural landscape: these reveal a clear organisation of living space at the settlement sites, consisting of mounds and flat areas. Understanding the relation of the mounds and adjacent flat areas within their environment allows a discussion on how, and for what purpose, the settlement was established at a particular location, and provides clues about its spatial organization.

Colonial encounter

After Columbus landed in the Caribbean during his famous round the world trip, things did not go well with the native inhabitants in the whole Caribbean region. Hundreds of thousands of indigenous people died as a result of the colonial encounters, due to imported diseases, mistreatment, slavery and famine.

John McCarthy is primarily known for his investigative reporting on the U.S. Virgin Islands. A series of reports beginning in the 1990's revealed that there was everything from coliform bacteria to Cryptosporidium in locally-bottled St. Croix drinking water, according to a then-unpublished University of the Virgin Islands sampling. Another report, following Hurricane Hugo in 1989, cited a Federal Emergency Management Agency (FEMA) confidential overview that said that over 40 percent of the U.S. Virgin Islands public lives below the poverty line. The Virgin Islands Free Press is the only Caribbean news source to regularly incorporate the findings of U.S. Freedom of Information Act requests. John's articles have appeared in the BVI Beacon, St. Croix Avis, San Juan Star and Virgin Islands Daily News. He is the former news director of WSVI-TV Channel 8 on St. Croix.
