A team of scientists are using airborne lidar mapping to study Mayan architecture, to better understand the social status of previous inhabitants. Their findings were recently published in the Journal of Archaeological Science (1).
Airborne lidar survey systems consist of a laser scanner, an inertial measurement unit (IMU), and a global positioning system (GPS) that are attached to aircraft units like helicopters or airplanes. This method is used to create a point cloud containing the X, Y, and Z-coordinates of whatever subject is scanned (2). These techniques are often used to analyze large pieces of land, including Mayan settlements.
Architecture is a major indicator of wealth and status in ancient Mayan culture, with materials, size, and local distributions being key factors in identifying and inferring social, economic, and political relations between communities. The researchers examined the residential structures representing different wealth and status across several datasets. The researchers studied how viable the architecture can be for indicating wealth and status, regularities in size and distribution of vaulted structures in different settings, and patterns in spatial distribution of vaulted architecture as proxies for differences in wealth and status within different settlement regions.
The proposed method was applied to 11 lidar datasets (about 111,000 structures). One notable finding was that only 30% of the structures held vaulted architecture, which confirms that this type of structure was restricted to more wealthy people in Maya society. It was also revealed that house sizes play a factor in this as well. Larger, vaulted structures were built most frequently in urban and larger plaza areas, with these groups being distributed through periurban and rural areas at regular intervals. This suggests that elite groups were distributed through landscapes to manage as much of an area as possible, with the chances of administrative and ceremonial functions being involved being likely. As for non-elite residences, they were often well-defined due to a lack of structure clusters and were often found near other larger groups, inferring that they represent neighborhoods and/or districts held by the elite “houses” surrounding them.
The scientists’ architectural analysis highlighted the presences of elite features within Maya architecture, with the frequency of buildings with said features being enough to infer that elite Mayans often lived within the vicinity of less affluent peers. This could lead to new insights on how Maya communities were organized, and according to the scientists, the findings in this study “[highlight] the importance of top-down processes in the formation of Maya urban and rural landscapes in contrast to prevailing views” (1).
