Data supporting the geomorphology of the Humadal Creek, Doña Juana Volcanic Complex, Colombia

Abstract

The dataset compiles high-resolution imagery of landform features of the SW flank of the Doña Juana Volcanic Complex, Colombia. Images were acquired with an unmanned airborne vehicle during June, 2018, using two DJI quadcopter Phantom 4 Pro, equipped with a 20 MP camera. We captured 4575 NADIR images with an approximated height of 120m above ground level and a 70% overlap. We performed 20 flights, which covered a top-down elevation difference of ~900 m and a 5.5 km along the Humadal Creek length. Measurements were staggered, considering the significant altitude differences along the creek. Information includes a digital terrain model (DTM) with a 4.7cm ground sampling distance (GSD).
