Abstract

Using UAVs for high-resolution mosaic production has become a common practice across various applications. This study focuses on selecting sections of rocky riverbeds to calibrate flight height parameters that optimize the observation of rock fractures. Basic statistics were employed to validate the differences between each selected height regarding the density and intensity of fracturing. It was observed that a height of 20 m allows for optimal visualization and a greater number of observable fractures. However, heights of 50 m and 100 m, while allowing for the observation of fewer fractures, exhibit small average differences (yet statistically significant) when compared to each other. Flight conditions, such as surveying time, may either enhance or minimize these differences.
