The greater and greater accessibility of drones and higher imaging cameras has made aerial photography more and more popular. For archeologists, this has also meant a potential to use thermal imagery in conducting field data research. This research helps archeologists identify the makeup of soil, its moisture and vegetation cover.
A research team lead by Jesse Casana has published the results of using aerial thermal imagery at six different sites. The results that aerial thermal imagery can be effectively used in many different conditions.
At the different sites, the team was able to discover features that could not have been found using land based thermal imagining. In fact, they found that they were able to discover sub surface artefacts by filtering out the surface vegetation.
Going forward, this technology could be very useful for archeologists in their field surveying work. The results were published in the journal Advances in Archaeological Practice.
