Resumen
Este proyecto se llevó a cabo como parte del programa de ingeniería geomática y topografía de la Universidad de
Jaén, España. Su principal objetivo era profundizar en el campo emergente de la tecnología LiDAR. La atención se
centró en la implementación práctica, ilustrando el proceso de procesamiento de datos LiDAR para generar
modelos digitales de terreno y superficie.
El proyecto comenzó adquiriendo datos LiDAR brutos de la empresa implicada en el proyecto Nacional PNOA
español. Estos datos se filtraron cuidadosamente para eliminar cualquier imperfección. Siguió una rigurosa
evaluación de calidad, comparando los datos con los estrictos estándares del Instituto Geográfico Nacional.
Después de corregir los errores identificados, clasificamos las nubes de puntos LiDAR. Este paso diferenció puntos
en la escena capturada, proporcionando una base sólida para generar modelos digitales. Se crearon modelos
digitales de terreno y superficie para representar fielmente la topografía y los elementos de la superficie.

The focus was on practical implementation, illustrating the process of LiDAR data processing to generate digital terrain and surface models. The project began by acquiring raw LiDAR data from the company involved in the Spanish National PNOA project. These data were carefully filtered to remove any imperfections. A rigorous quality assessment followed, comparing the data against the stringent standards of the National Geographic Institute. After correcting any identified errors, we classified the LiDAR point clouds. This step differentiated points in the captured scene, providing a solid foundation for generating digital models. Digital terrain and surface models were created to faithfully represent the topography and surface elements.
