Location, Maps, and Imagery: The Key Interconnections

What do a high-resolution imaging satellite, a smartphone app, and a bird-of-prey in the wild have in common?  They all make use of knowledge of physical location.  This talk gives an overview of how one's location is calculated, what makes it so useful, and the ways maps and remote-sensing imagery are combined with our knowledge of location to enhance our understanding of our ever-changing society and the environment.  Illustrative examples are drawn from experimental biology, emergency disaster response, and the oil and gas industry.

Dr. Scott Douglas is an SMU professor, researcher, educator, and entrepreneur.  Over twenty years ago, he developed one of the first successful procedures for the active cancellation of sound in a room. More recently, he developed mathematical techniques for picking out and recording individual voices in a crowd using several microphones in tandem. As an electrical engineer, Professor Douglas conducts research in the fields of wireless geolocation, adaptive filtering, blind deconvolution and source separation, and hardware implementations of digital signal processing systems.  He is active nationally and internationally in the Institute of Electrical and Electronics Engineers and was general chair of the International Conference on Acoustics, Speech, and Signal Processing held in Dallas, Texas, in 2010.  He is the co-founder and chief technology officer of LGT Corporation, a geological and geophysical service company applying advanced signal processing methods to problems in the oil and gas industry.

He received his B.S., M.S. and Ph.D. degrees in Electrical Engineering from Stanford University.
