New RBC Publication: Remote Sensing in Freshwater Fisheries

Top panels (left to right): Aerial imagery, airborne LiDAR vegetation height (first laser return minus last laser return) and ground elevation (last laser return), and solar exposure on surface water showing spatial variation in vegetation height (reflecting vegetation type and structure), hillslope and floodplain topography, and stream shading for the Boise River, Boise, Idaho. Bottom panel: Transverse profile of vegetation and floodplain elevations from LiDAR data. LiDAR data resampled to 3-m spatial resolution.

A literature review co-authored by River Basin Center Scientific Director Seth Wenger and Post-doctoral Associate Douglas Leasure has appeared in the October 2017 issue of Fisheries magazine, which is published by the American Fisheries Society.  This featured article, titled Satellite and Airborne Remote Sensing Applications for Freshwater Fisheries, discusses how technological developments have allowed the applications of remote sensing to broaden, especially as costs have decreased.  Remote sensing, the scanning of the earth by satellite or aircraft to gather data, allows researchers to understand large-scale environmental patterns.  The sensors can be used to study a variety of factors such as land use, climate, and primary productivity.  

The article details recent research where remote sensing is used for these and other applications.   Remote sensors can collect data at higher spatial, temporal, and spectral resolutions than ever before and data is becoming more readily accessible, so more innovative and important research can be done. Recent advances in remote sensing have generated an impressive volume of data sets and related software; the article provides a ‘roadmap’ on how to get acquainted with using remote sensing.
