Abstract

Abstract: We use the results of a high-resolution lidar survey to assess the advantages and limitations of archaeological applications of lidar data and address some of its methodological challenges. Our data come from the Mopan and Macal River valleys in western Belize, a region that includes several ancient Maya political centers and their hinterlands. Visual inspection of the lidar data has revealed many new sites and new features at previously mapped sites, and these findings significantly enhance our understanding of the valley's cultural history and political dynamics. By comparing data from prior systematic pedestrian surveys, visual and TPI analysis of the lidar data, and analysis of other remotely sensed data, we assess the limits of mound visibility in the lidar data and examine how vegetation and topographic factors impact those limits. We also present slope analysis as a useful tool for predicting whether mounds were constructed in the Preclassic period (1000 B.C.–A.D. 250) or the Classic period (A.D. 250–900).
