Resumen

El uso de VANT para la producción de mosaicos de alta resolución se ha convertido en una práctica común en diversas aplicaciones. Este estudio selecciona tramos de lechos rocosos de ríos para calibrar los parámetros de altura de vuelo que optimizan la observación de fracturas en la roca. Se empleó estadística básica para validar las diferencias entre cada altura seleccionada respecto a la densidad y la intensidad del fracturamiento. Se observó que una altura de 20 m permite una visualización óptima y un mayor número de fracturas observables. Sin embargo, alturas de 50 y 100 m, aunque permiten la observación de menos fracturas, muestran diferencias promedio pequeñas (pero estadísticamente significativas) al compararse entre sí. Las condiciones de vuelo, como el horario de levantamiento, pueden realzar o minimizar estas diferencias.
