QUANTIFICATION OF MOGOTE ASYMMETRY: ARECIBO, PUERTO RICO
Profiles were generated for 104 mogotes and the resulting metrics show that there is no consistent topographic asymmetry in the data derived from the DEM, regardless of underlying geologic unit. However, our field observations indicate that the DEM used is likely too coarse to accurately capture the asymmetry of individual mogotes.
To carefully measure the true slope of one target feature, we used the Structure from Motion technique on a mostly unvegetated mogote using over 400 aerial images captured with a drone. The resulting 3D Model was converted to a high-resolution DEM, which was used to construct much more precise topographic profiles. The results of this analysis will be presented and compared with the results from the coarse 25m2 DEM.
