Abstract

fetched live from OpenAlex

Abstract Lidar has been revolutionary to the understanding of ancient Maya anthropogenic landscapes. This is no more apparent than in western Belize, where the scale and resolution of these images have identified vast networks of agricultural terrace systems, revealing their true extent and density. This paper moves beyond the initial identification of terrace distribution to use lidar imagery in combination with digital elevation models (DEM) and hydrological mapping programs (Arc Hydro) to explore the drainage catchments associated with agricultural terraces at the ancient Maya site Waybil, a minor center within the Minanha polity in the North Vaca Plateau. We specifically address how the builders of these relic agricultural features worked with the natural topography to manipulate and create more effective catchments and drainage routes. Results from hydrological modeling describe how terraces created smaller drainage catchments by increasing lower levels of flow accumulation and redirecting routes laterally across the topography. Over a decade of research within this sub-region provides the necessary survey, excavations, and chronological datasets to accurately assess the efficacy of the combined methods for relic terrace drainage analysis.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
