Summary

This talk compares methods used for the topographical mapping of the archaeological site of Matacanela. Specifically, we compare the results of the GIS processing of LiDAR data collected and distributed for no charge by the Instituto Nacional de Estadística y Geografía with the results of traditional topographical mapping, undertaken using a Sokkia total station. For the purposes of project planning, the LiDAR data was processed, and maps were generated using GIS. These LiDAR-based data enabled the first topographical map of Matacanela and its environs to be generated, the project area to be defined, and for cost and time assessments to be estimated for the purposes of budget preparation. Because of the uncertainty of the quality and resolution of the LiDAR data, topographical mapping of the site area was considered an important step to "ground-truth" the LiDAR, and to collect more fine-grained measurements from small-scale architectural features, artifact concentrations, and other cultural and natural features that may have been missed during the fly-overs. Here, we consider the two approaches and the type and quality of data achieved by each, as well as the benefits and drawbacks of using either approach alone.
