Dataset Information

This dataset comprises high-resolution three-dimensional (3D) point clouds generated from 0.5-m-resolution Pleiades stereo satellite imagery using Agisoft Metashape (v.2.0.2). The dataset covers a >70-km-long corridor across the Haouz Basin, extending from southwest of Guemassa (31°21′58.56″N, 8°25′45.40″W) to east of Marrakech (31°39′12.46″N, 7°56′41.02″W), Morocco, along the Guemassa fault. The high-resolution point clouds provide detailed three-dimensional topographic information for identifying and mapping fault traces, scarps, displaced Quaternary surfaces, and other tectonic geomorphic features. These data support investigations of Late Quaternary fault activity, fault geometry, and surface deformation, contributing to a better understanding of active tectonics and seismic hazard in the western High Atlas region. Beyond tectonic geomorphology and geology, the dataset provides a valuable resource for high-resolution terrain analysis, hydrological modeling, environmental monitoring, remote-sensing applications, and archaeological investigations across the northern High Atlas region.
