digital surface model: The DSM represents surface elevations such as the height of vegetation and buildings. Since water bodies can introduce noise, we selectively removed areas manually where inland water bodies introduced excessive noise. The DSM is a single-band, 32-bit floating point GeoTIFF file with a GSD of 0.13 m; the No Data value is set to -32767. orthoimagery: The orthoimage is a three-band (red, green, blue), 16-bit unsigned GeoTIFF file with a GSD of 0.065 m per pixel; the No Data value is set to 0.

We thank the Native Village of Pilot Point for funding supporting the creation of these data products. These data were produced by the University of Alaska Fairbanks Arctic Coastal Geoscience Lab (UAF-AGCL). The DGGS Coastal Hazards Program and UAF-AGCL work collaboratively to collect baseline data in Alaska communities and to produce raw data file publications for public access and archiving.
The orthoimage and elevation data were collected for assessing coastal hazards and changes.
