Satellite and Aerial Imagery: Viewing Ecology from Above

FLBS scientists have extensively utilized, and in fact pioneered, aspects of the use of aerial sensors and imagery (satellite and aircraft mounted) to examine ecological characteristics and patterns. At the watershed scale, FLBS has used multi-spectral imagery from both satellites and aircraft, in concert with on-the-ground Acoustic Doppler Profilers which can measure water depth, velocity and sediment movement, to develop techniques to classify, quantify, and map aquatic and riparian habitat. Additionally, by using Light Detection and Radar (LIDAR), FLBS researchers have constructed detailed topographic maps and information about river flood plains and lake shorelines.

At the global scale, FLBS researchers have worked extensively with NASA’s satellite remote sensing programs (eg Landsat, MODIS and SMAP) and have been involved in the development and oversight of new sensors and analysis techniques. These technologies have resulted in extensive discoveries pertaining to the earth’s soil moisture, drought, freeze thaw cycles, and climate variability.
