“…In the last few years, the civil use of Unmanned Aircraft Systems (UAS), commonly named drones, has increased considerably thanks to its great potential and versatility. The ability of UAS to carry a wide assortment of sensing equipment and reach hard to access areas has prompted their adoption in varied professional fields, such as public safety (Cerreta et al 2020), environment monitoring (Gonçalves et al 2020) or construction safety (Rodrigues and Bastos 2019).…”

Potential civil applications of Unmanned Aircraft Systems (UAS), commonly known as drones, have risen steeply duringthe last decade, mainly due to their versatility and capability of spatial data gathering. Nonetheless, real use of UAS isquite restricted nowadays, primarily due to safety and regulatory constraints. This multidisciplinary project aims to performspecific safety assessments using the SORA methodology adopted by the European Aviation Safety Agency (EASA) anddevelop documentation and procedures for operators to follow, complying with all required safety and regulatoryrequirements. As a result, DEURPAS-UPV is the first Spanish drone operator belonging to a university to be authorizedby Spanish civil aviation agency (AESA-Agencia Estatal de Seguridad Aérea), to perform drone flights in urban areas, incontrolled airspace and during the night. In addition, DEURPAS-UPV has performed the first authorized experimentaltransport operations using drones in Spain. The results from safety assessment and designed procedures have beensuccessfully applied to the operation of Safety and Emergency service providers, such as Valencia Local Police Corps andthe Valencian Emergency and Safety Response Agency (AVSRE - Agencia Valenciana de Seguridad y Respuesta a lasEmergencias). Overall, this project has served as an enabler for more complex and safer UAS operations, from theoperator’s point of view, which will help break the barriers related to the use of these aircraft, with huge potential ingeomatics applications.

The use of medium/high-density LIDAR (Light Detection And Ranging) data for land modelling and DTM (Digital Terrain Model) is becoming more widespread. This level of detail is difficult to achieve with other means or materials. However, the horizontal and vertical geometric accuracy of the LIDAR points obtained, although high, is not homogeneous. Horizontally you can reach precisions around 30-50 cm, while the vertical precision is rarely greater than 10-15 cm. The result of LIDAR flights, are clouds of points very close to each other (30-60 cm) with significant elevation variations, even if the terrain is flat. And this makes the triangulated models TIN (Triangulated Irregular Network) obtained from such LIDAR data especially chaotic. Since contour lines are generated directly from such triangulated models, their appearance shows excessive noise, with excessively broken and rapidly closed on themselves. Getting smoothed contour liness, without decreasing accuracy, is a challenge for terrain model software. In addition, triangulated models obtained from LIDAR data are the basis for future slope maps of the land. And for the same reason explained in the previous paragraph, these slope maps generated from high or medium density LIDAR point clouds are especially heterogeneous. Achieving uniformity and greater adjustment to reality by reducing the natural noise of LIDAR data is another added challenge. In this paper, the problem of excessive noise from LIDAR data of high (around 8 points/m 2 ) and medium density (around 2 points/m 2 ) in the generation of contour lines and terrain slope maps is raised and solutions are proposed to reduce this noise. All this, in the area of specific software for the management of TIN models and GIS (Geographic Information System) and adapting the alternatives proposed by these programmes.
