Summary
A high-resolution, high vertical accuracy Digital Surface Model (DSM) of Mt. Etna was derived from Pleiades satellite data using the National Aeronautics and Space Administration (NASA) Ames Stereo Pipeline (ASP) tool set (https://ti.arc.nasa.gov/tech/asr/groups/intelligent-robotics/ngt/stereo/). The NASA Ames Stereo Pipeline (ASP) is a suite of free and open source automated geodesy and stereogrammetry tools designed for processing stereo imagery captured from satellites (around Earth and other planets), robotic rovers, aerial cameras, and historical imagery, with and without accurate camera pose information. The methodology used by the ASP software is similar with structure-from-motion (SfM) methodology using stereo triangulation [...]

Purpose
The Mt. Etna volcano (Sicily, Italy) is periodically characterized by explosive and effusive eruptions and represents a potential hazard for several thousands of local people and hundreds of tourists present on the volcano itself. The high-resolution high accuracy DSM was derived from Pleiades satellite imagery acquired on July 28, 2015. The data is in raster digital format, 2 m spatial resolution in Universal Transverse Mercator projection, zone 33N. The vertical root mean square error is 0.78 m.
