Remote Sensing Research and Development

EROS has been an integral part of earth-observation science since the launch of the first Landsat satellite in 1972, and is renowned for its experience and proficiency in remote sensing technology. We have been providing technical expertise and services to the USGS and its partners across government, industry, and academia for decades, with a particular emphasis on the capability, r
