Abstract
Maya archaeology has witnessed a paradigm shift in interpretations of the past with regards to the structure and organization of ancient societies as a result of the introduction of lidar to the field a decade ago. Lidar provided control of spatial parameters in a way that had not been previously possible. But, the introduction of this technology has also involved researchers in a series of broader ethical debates. While archaeology has always provided huge data sets for processing, the digital lidar files are even larger and also need appropriate long-term storage and management considerations. It is here that there are differences of opinion worldwide on how to treat lidar data as scientific and open yet national and protected datasets. Some countries do not want fully public access to these files because of the potential danger posed to the looting of their heritage and security or military concerns. Yet, to a large extent, technology is overtaking some of the debate over accessibility, especially as newer satellite technology will surely alter the perceived physical boundaries and challenge the sovereignty of modern nation-states. However, how lidar is used and accessed in the future has become a cross-national issue that is worthy of being addressed in greater detail.
