    • Hyperspectral imagery to study harmful algal blooms (HABs) of Lake Erie, Lake St. Clair, and Saginaw Bay, Lake Huron of the Great Lakes region

    Metadata Updated: September 19, 2023

    The hyperspectral images in this collection contain flights over the western basin of Lake Erie, and Saginaw Bay, Lake Huron of the Great Lakes region during the HAB season from typically June until the end of October. Images were acquired from a manned aircraft with a Resonon hyperspectral imaging camera. Each flight has approximately 200-400 images along the flight trajectory that are in band interleave per pixel (.bip) or band interleave per line (.bil) format. The files are in raw binary, radiance values, and reflectance values. The resolution is typically 1 meter or less depending on the altitude that is flown. The flight path covered the Michigan and Ohio drinking water intake locations and also the Cooperative Institute for Great Lakes Research (CIGLR) water quality monitoring stations in western Lake Erie. Each flight took into account the solar zenith angle to minimize sun glint correction. The data are currently in raw and radiance formats that were converted to radiance using the calibration files provided by the manufacture and no other corrections have been made. The camera is sent annually to be calibrated by the manufacturer. Imagery was collected to monitor harmful algal blooms (HABs) over the western basin of Lake Erie and Saginaw Bay, Lake Huron. Funding for this project was received via the Great Lakes Restoration Initiative (GLRI) from the U.S. Environmental Protection Agency (USEPA).
