Summary

Multispectral satellite images from two reaches of the Buffalo National River in northern Arkansas were acquired between August 6, 2021, and September 15, 2021, to support research on remote sensing of benthic algae. The images included in this data release were obtained by the WorldView3 and Planet SkySat sensors. The original images were cropped to produce smaller subset images focused on each of the two primary study reaches. In addition, the WorldView3 images were geo-referenced and warped to improve alignment with field measurements. This data release includes a comma-delimited (*.csv) text file with a listing of the satellite images with columns: River, Reach, AcquisitionDate, Sensor, PixelSizeMeters, Projection, Datum, and ImageFileName.

Purpose

The purpose of this study was to develop and test remote sensing methods for mapping benthic algae in river channels from aerial photographs and satellite images. The satellite images included in this data release were used to produce spectrally based depth estimates and classifications of benthic algal coverage.
