ENGERGY BALANCE MAPS FROM REMOTELY SENSED IMAGERY
Synoptic maps showing the spatial distributions of energy- related phenomena over the terrestrial surface have not been-feasible with traditional instruments and observation techniques. The advent of calibrated multispectral optical scanners, however, has made possible the rapid measurement of surface energy emittance and reflectance. Data acquired in a few minutes with scanners from airborne platforms can be translated into maps showing urban heat islands, surface albedos, energy absorbed by the surface, and net radiation. An experiment using the ERIM My-7 scanner, and Baltimore as a test-site city, has successfully yielded isarithmic maps of these phenomena as they existed during an imaging over- flight. Methods for acquiring calibrated data from a scanner and the construction of maps from image transparencies are described and evaluated.
