This state-of-the-art technology is an innovation that has the advantage of acquiring a large amount of data in a short time. This technology together with UAV equipment has the advantage of obtaining a digital terrain model. The creation of 3D patrimony models, archaeological objects and sites in their current state requires specialized equipment, knowledge, and have a powerful methodology capable of digitally capturing and shaping geometric details and fine layout of these sites. Digital recording, documentation and preservation are required because our patrimony (natural, cultural or mixed) suffers from various anthropogenic and/or natural actions (natural disasters, climate change and forgetfulness of human neglect).

The technology is primarily used to quickly acquire three-dimensional information (3D). Cultural heritage objectives, bridges, cars, plants, rock crests, hydrotechnical nodes, highways, road accidents, and others can be modeled, analyzed and stored in a database, and if needed, make 3D laser documentation. At the moment, LiDAR is undoubtedly the most successful data acquisition technique introduced over the last decade (Lemmens, 2011). UAV-based LiDAR studies are particularly attractive for use in locations where there are regular landscape changes (e.g. in high erosion environments, building stability tracking), and so if LiDAR archives or other DSM archives (Digital Surface Model) need periodic updating (such as agricultural areas), appear on a scale that is too fine to be captured accurately by other topographic sensors in air or satellite. The ability of UAVs to fly in close proximity and with greater maneuverability than human crew will also provide a finer spatial resolution in the resulting DSMs and Digital Terrain Model (DTMs). In addition, through intelligent flight planning, UAV-LiDAR can achieve the collection of higher cloud point densities on key areas (James et al., 2007). As reference sources for obtaining a DEM using terrestrial spatial accuracy data, TLS data (Cook, 2017), LIDAR data, (Fonstad et al., 2013), total stations, GPS equipment and GPS RTK control points (Turner et al., 2015). The area of applicability of UAV equipment spreads through various civil applications, including reconstruction of high resolution areas (Anders et al., 2013), documenting cultural heritage and archaeological sites (Remondino, 2011), detection of agriculture and forest change (Mangan et al.,
