Digital elevation model of the Santa Maria volcano including the Santiaguito lava dome. The model was built using tri-stereo images acquired on the 15th January 2017 by the Pléiades satellite mission. Processing was done using the photogrammetry workflow in Erdas imagine and a height correction and hole-filling in QGIS. The final model is downloadable here in geotiff format with an approximate 1m resolution. Please note a major gap of the summit of Santa Maria due to cloud cover. This data is a resampled version of the DEM used by Zorn et al. (2020) for map visualization and georeferencing purposes.
