Photogrammetry-derived digital surface model and orthoimagery of the Usibelli Group type section, Suntrana Creek, Alaska

The Alaska Division of Geological & Geophysical Surveys (DGGS) conducted a photogrammetric survey in the Suntrana Creek area near Healy, Alaska. This survey includes most of the type section for the Cenozoic Usibelli Group, an economically significant coal-bearing succession. Aerial photographs and Global Navigation Satellite System (GNSS) data were collected on May 10, 2018. We processed these data using structure-from-motion (SfM) photogrammetric techniques to create a digital surface model (DSM) and orthoimage of the surveyed area. Data files available for download are tiled DSM and natural color (RGB) orthoimage GeoTIFFs. This Raw Data File provides open access to, and an open end-user license for, these data products. All files can be downloaded free of charge from the DGGS website (http://doi.org/10.14509/30425).
