Archaeological Prospection, EarlyView.ABSTRACT Temperate river floodplains present a significant challenge for archaeologists, as cultural and palaeoenvironmental remains are often difficult to locate but can be exceptionally well preserved, especially where groundwater levels are high. In these alluvial environments, the deposition of thick, fine‐grained sediments has potential to deeply ...

Archaeological Prospection, EarlyView.ABSTRACT Airborne laser scanning (ALS, lidar) has become a key method for studying ancient Maya landscapes, offering unprecedented visibility of anthropogenic terrain modifications in densely forested environments. Despite this progress, the visualization of elevation data remains understandardized, with many researchers relying on ad hoc or ...
