Working with archeologists in Belize, NCALM researchers were able to create topographical maps of a Mayan city through dense vegetation. These maps located ruins and features that hadn’t been discovered during years of more traditional archeological exploration and research.

With support from the National Science Foundation (NSF), the University of Houston’s National Center for Airborne Laser Mapping (NCALM) has, in the past few years: located ancient ruins, identified levees in danger of failing, charted land erosion following hurricanes, created flood maps for urban areas, found near-drought conditions in seemingly healthy plants, mapped the sea floor, ch

Dr. Saurabh Prasad joins the National Center for Airborne Laser Mapping and the Department of Electrical & Computer Engineering as an assistant professor. Dr. Prasad earned his Ph.D. degree in Electrical Engineering at Mississippi State University in 2008. He was an assistant research professor at the Geosystems Research Institute (GRI), and an adjunct assistant professor at the Electrical & Computer Engineering department at Mississippi State University from January 2009 through December 2011. At Mississippi State University, Dr. Prasad was the technical lead on several projects funded by NASA, NGA, and DHS as a PI/Co-PI.

Dr. Prasad's research interests include statistical pattern recognition and adaptive signal processing, with applications to automatic target recognition and land cover classification for hyperspectral remote sensing. In particular, his current research entails the use of information fusion techniques for designing robust statistical pattern classification algorithms for hyperspectral remote sensing.

NCALM Shallow Water Bathymetry System – Now Available

The National Science Foundation supported National Center for Airborne Laser Mapping (NCALM) contracted with Optech Inc, to develop a first generation high pulse rate green (532 nm) wavelength LiDAR sensor. The new green sensor, designed to operate with the electronics rack from the nearIR Gemini system currently used by NCALM, is capable of acquiring bathymetric data at pulse rates up to 70 kHz, with full return waveform digitization, in water depths up to 10 meters (assuming the diffuse attenuation coefficient of the water is less than 0.1/m, and the bottom reflectivity is >10%). At a flying height of 300 meters, the nominal outgoing pulse density is 10 points per square meter, with a 30 centimeter spot diameter on the water surface. This represents a significant improvement in horizontal spatial resolution over existing off-the-shelf commercial LiDAR bathymetry systems. Assembly of the new sensor was completed in June 2011, and factory performance and system shake-down flight testing are currently underway. NCALM is interested in collaborating with the scientific community in research applications that would benefit from high density and accuracy shallow water bathymetry.

Dr. Guoquan Wang joins NCALM and the Department of Earth & Atmospheric Sciences as an assistant professor. Dr. Wang earned his Ph.D. (2001) in Solid Earth Geophysics from the Institute of Geology, China Earthquake Administration. He was an Assistant Professor of the University of Puerto Rico at Mayaguez from August 2006 to August 2011 and tenured on July 1, 2011. He and his colleagues established the Puerto Rico and Virgin Islands Real-Time High-Rate GPS Network, which has become an infrastructure for multi-hazards (e.g., earthquake, tsunami, hurricane, landslide, subsidence) study and structural health monitoring in this region.

Dr. Wang is a Co-PI of the Continuously Operating Caribbean GPS Observational Network (COCONET), an NSF funded instrumentation project with the mission of installing 50 new permanent GPS stations and refurbishing 50 existing stations in the Caribbean and Caribbean-border nations in five years (2011-2016). His most recent research interests focus on the applications of high-precision GPS and LiDAR technologies in geological hazards study.

Dr. Hyongki Lee joins NCALM and the Geosensing Systems Engineering and Sciences program at the University of Houston as a new Assistant Professor. Dr. Lee is a geodesist and earned his Ph.D. (2008) in Geodetic Science from Ohio State University. He received his B.Sc. (2000) and M.Sc. (2002) in Civil Engineering from Yonsei University, South Korea. His doctoral dissertation focused on satellite radar altimetry and its applications on terrestrial surfaces.

After his graduation, Dr. Lee continued to work at the School of Earth Sciences and Byrd Polar Research Center, Ohio State University as a Postdoctoral Researcher and Research Scientist for three years. He has been working on various disciplines of Earth sciences using satellite altimetry, gravimetry, and synthetic aperture radar measurements, publishing more than 20 peer-reviewed journal articles. His recent research interests include monitoring natural hazards such as flood, drought, hurricane, and tsunami using satellite geodetic observations, towards their potential warning and disaster loss mitigation.
