- Abstract
This paper compares the results of a survey with aerial LiDAR and Structure from Motion at the Inka site El Shincal de Quimivil. This site is located in the province of Catamarca and is considered one of the most emblematic Inka political, administrative and ceremonial centres in the Northwest Argentina. In order to compare and explore the potential of both techniques, statistical calculations of height differences were made and spatial analysis of visibility and human mobility, understood respectively as the visual representation of a space and the ability to move through it, were carried out. The greatest differences were registered in areas with dense vegetation and high slopes. Naturally, the reference is the Digital Terrain Model determined with LiDAR, which is not affected by these circumstances and has a quality of a few centimetres in all components. On bare ground, both models are comparable. Therefore, one of the keys to choose between these techniques is to decide how to use each of them according to the type of terrain, the scale of work, and acceptable error.
