Fodar Orthomosaic and Digital Elevation Model of the Totatlanika River Corridor (Alaska) Acquired August 2021

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.
