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.

Geosensing Systems Engineering Instructional Faculty Positions

The Department of Civil and Environmental Engineering (CEE) at the University of Houston invites applications for part-time instructional faculty positions in the Geosensing Systems Engineering (GSE) program.

Qualifications: The applicant must have an earned Ph.D. in geomatics, geodetic science and/or a related field of civil/environmental/aerospace/mechanical engineering or equivalent professional experience. The candidate should be able to teach undergraduate and/or Master’s level graduate courses related to one or more of the following areas: Geostatistics (CIVE 6393), Fundamentals of Plane Surveying (CIVE 3380), Legal Principles and Boundary Surveying (CIVE 4382), Digital Photogrammetry (CIVE 5375) and Survey Measurement & Analysis (CIVE 5386). Details on these courses can be found at the following link: (http://publications.uh.edu/preview_program.php?catoid=25&poid=10051&returnto=8859).

University and Department: The University of Houston is located in a park-like campus a few minutes from downtown Houston with over 37,000 undergraduate students and 8,000 graduate students. The CEE department currently has 20 tenured or tenure-track faculty members with over 260 undergraduates, and over 130 graduate students. Houston is the fourth largest city in the U.S. with over 6.6 million in population in the greater Houston area. It is the "energy capital of the world" and houses the largest medical center in the world. The greater Houston area offers state-of-the-art recreational facilities, world-class arts and cultural activities, excellent schools, and affordable housing.

How to Apply: Applications should include a cover letter, complete contact information for three professional references, and a curriculum vitae. Application package should be sent to Dr. Craig Glennie via email at clglennie [at] uh.edu.

The University of Houston, with one of the most diverse student bodies in the U.S., seeks to recruit and retain a diverse community of scholars.

The University of Houston is an equal opportunity/affirmative action employer. Minorities, women, veterans, and persons with disabilities are encouraged to apply.

The University of Houston is responsive to the needs of dual career couples.

2019 Mexico and Central America Lidar Collection Campaign

The National Center for Airborne Laser Mapping completed four projects in Chiapas and Tabasco, Mexico, for several PIs. After small delays upon entering the country, NCALM was able to map over 1,000 km2, with eight flights over nine days, throughout east Tabasco, the Palenque area, and northeast Chiapas. The team based out of the Villahermosa International Airport.

Tenosique TeamA special thanks goes to Carlos Gustavo Rosado Macosay, who granted access and electricity in his home to set up and operate a GPS base station in Tenosique. This was made possible through Takeshi Inomata's student Miguel Omar Garcia Mollinedo, and his father Miguel Garcia Hernandez. The NCALM team is grateful to Charles Golden and the Proyecto Arqueológico Busiljá-Chocoliá team for operating a base station at Finca Vallescondido, and to the Hotel Tulijá Express Palenque for providing a location for the final GPS station. Additionally, Keiko Taranishi of INAH Palenque did tremendous work in assisting NCALM complete the projects.

Airborne Mapping in Texas and New Mexico

A new NCALM dataset has been released by OpenTopography. The dataset, covering 63 km2 over McKittrick Canyon in West Texas and Southern New Mexico, was collected for a 2017 Seed Proposal titled, “Quantifying Rock Strength Controls on Landscape Morphology in the Guadalupe Mountains, NM/TX.” Read more at opentopography.org.

Zhiyue Sun Defends Ph.D. Dissertation

Doctoral student Zhiyue Sun successfully defended his dissertation titled, "Estimating Glacier Ice Thickness and Mass Balance using Multiple Spaceborne Geodetic Techniques." Numerous spaceborne remote sensing techniques have been used to obtain different geodetic observations of glaciers. Contemporary estimates from these approaches yield large discrepancies in certain glacierized areas, such as the Nyainqen Tanglha, and other glacierized regions, such as the Novaya Zemlya, have been under-studied. To characterize and quantify accurate glacier mass balance estimates over Nyainqen Tanglha and Novaya Zemlya, the dissertation proposed an iterative velocity-based method to estimate thickness.

First, a new iterative method, which estimates ice thickness using surface velocity and surface topography was presented. Second, traditional spaceborne techniques of observing surface mass balance were tested in the Novaya Zemlya. Finally, the proposed thickness estimate method was applied to the four largest glaciers in the Nyainqen Tanglha. Thickness distribution maps from 2008 to 2016 were obtained, and mass balance and thickness changes were determined accordingly.

Zhiyue’s Geosensing Systems Engineering & Sciences (GSES) advisor was Dr. Hyongki Lee. Congratulations, Zhiyue!
