Imaging growing lava domes has remained a great challenge in volcanology due to their inaccessibility and the severe hazard of collapse or explosion. Here, we present orthophotos and topography data derived from a series of repeated survey flights with both optical and thermal cameras at the Caliente lava dome, part of the Santiaguito complex at Santa Maria volcano, Guatemala, using an Unoccupied Aircraft System (UAS). The data archived here supplements the material detailed in Zorn et al. (2020, Note, all files are saved in WGS 84 / UTM Zone 15N format. The data are provided the following .zip folders:- 2020-001_Zorn-et-al_DEM-Geotiffs-zip: DEMs of surveys A-D in geotiff format (.tif)- Orthophotos of surveys A-D and 2 thermal surveys as Tiff-images (.tif). A .jpg of the color scale for the thermal data is also included- Point clouds of surveys A-D, 2 thermal surveys (.las)
