Bender, A.M., Nolan, M., 2021, Fodar orthomosaic and digital elevation model of the Totatlanika River corridor (Alaska) acquired August 2021: U.S. Geological survey data release, https://doi.org/10.5066/P9K7CFRI

Summary

This dataset provides a digital elevation model derived from airborne fodar data acquired in 2021 on August 31 over the Totatlanika River in central Alaska. The term "fodar" is a portmanteau of foto and lidar, coined by Matt Nolan, which describes a method of quantifying the color and elevation of Earth’s surface via airborne small-format digital camera photography.

Purpose

This dataset was acquired for the purpose of mapping and quantifying surface processes (e.g., river incision, landslide erosion) along the Totatlanika River, which drains the minerally endowed and tectonically active northern Alaska Range. The 25 cm/cell elevation data that this data release provides are 25-fold higher resolution than the previously available 5 m/cell Alaska IfSAR digital elevation model.
