Welcome

The mission of the National Center for Airborne Laser Mapping (NCALM) is to:

  • Provide research-quality airborne light detection and ranging (lidar) observations to the scientific community.
  • Advance the state of the art in airborne laser mapping.
  • Train and educate graduate students with knowledge of airborne mapping to meet the needs of academic institutions, government agencies, and private industry.

NCALM is based at the University of Houston and is operated in partnership with the University of California, Berkeley. The center is supported by the National Science Foundation and is associated with the multi-disciplinary Geosensing Systems Engineering & Sciences graduate program at the University of Houston.

Hyongki Lee, assistant professor of civil and environmental engineering at the Cullen College, is making quite a splash. Lee has accomplished so much in the field of water you could say he’s all over the map, but soon his work will be high above the map. He’s helped Pakistani officials manage water resources and was selected by NASA to do the same in Indochina.

Ph.D. Student Opportunities in Geosensing Systems Engineering & Sciences

The Geosensing Systems Engineering & Sciences (GSES) Graduate Program in the Department of Civil & Environmental Engineering at the University of Houston, in conjunction with the NSF National Center for Airborne Laser Mapping (NCALM), is seeking qualified applicants (with backgrounds in engineering, geomatics, geosciences, physics, astronomy, computer sciences, or geography) interested in: Design, development, and testing of lidar, digital image, and hyperspectral sensors; Research applications of lidar observations, including when combined with digital imagery or hyperspectral measurements; Study of satellite altimetry for applications in hydrology, glaciology, geodynamics, and sea levels; Applications of terrestrial laser scanning, airborne lidar, and GPS in natural hazards studies and mitigation; and Applications of airborne remote sensing techniques in geomorphology, climate/weather studies, hydrology, and tectonics.

Additionally, U.S. citizens interested in single photon and Geiger mode lidar analysis are encouraged to apply for opportunities to participate in sensor design and error analysis, geometric and radiometric calibration algorithm development, data filtering and feature extraction, comparison and fusion with traditional active and passive remote sensing products, and multi-sensor fusion design and data exploitation.

Please visit: ncalm.cive.uh.edu/gses/geosensing, for more information.

The application process and forms can be found on the Civil & Environmental Engineering website. Interested students can contact Dr. Craig Glennie at: clglennie [at] uh [dot] edu (subject: GSES%20Graduate%20Program%20Information%20Request) .

Deadline: February 1st, 2017

Professor Hyongki Lee is helping manage water via satellite for Indochina

If it has to do with water, you can bet Assistant Civil and Environmental Engineering Professor Hyongki Lee has an appetite whet for it. Fresh off the success of helping Pakistani officials manage water resources, he’s at it again, now selected by NASA to manage water for Indochina.

For Lee, it’s an issue of fairness.

Zhigang Pan Defends Dissertation

Zhigang Pan defended his Ph.D. dissertation, "Shallow Water Bathymetry Using Full Waveform Bathymetric LiDAR and Hyperspectral Imagery." High-resolution airborne hyperspectral imagery and high-resolution, low-pulse energy, full waveform lidar were investigated to determine their capabilities for predicting water column characteristics and bathymetry. Using multiple evaluations, significant improvements in point density, multiple return detection, water turbidity, and accuracy were determined for full waveform bathymetric lidar. Additionally, improvements were made to the determination of shallow water bathymetry, water turbidity, and water column constituent concentration using hyperspectral imagery.

Zhigang becomes the fifth Geosensing Systems Engineering & Sciences (GSES) doctoral student to defend in 2016. His advisor was Dr. Craig Glennie. Zhigang will be working closely with Dr. Glennie and Leica Geosystems as a postdoctoral researcher, where he will be concentrating on single photon lidar calibration and filtering.

Congratulations, Zhigang!
