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.

UH Professor Continues Work With NASA and Mekong River Stakeholders To Address Flooding and Other Critical Issues
Hyongki Lee, associate professor of civil and environmental engineering at the UH Cullen College of Engineering, has a lot of experience using data collected by Earth-observing technologies (such as satellites) for solving water management issues on Earth.
With his latest grant, Lee is diving deeper into addressing critical concerns such as land subsidence, flood forecasting and groundwater management in the Mekong region of Southeast Asia.
Principal investigator Lee and his co-investigator Faisal Hossain of the University of Washington recently won their second NASA SERVIR program grant. The three-year project, titled "Operational Services for water, disaster and hydropower applications for lower Mekong populations using NASA earth observations and models," received $661,443 in funding...

River Discharge Estimates Improved Using Ensemble Learning
Ph.D. candidate Donghwan Kim successfully defended his dissertation titled, "Ensemble Learning Regression for Estimating River Discharge Using Remotely Sensed Data and Hydrological Model." A new approach to estimating river discharge using ensemble learning regression (ELQ) was developed. Ensemble learning designates a series of procedures to train several functions and combine their results based on an integrating rule. ELQ generates more accurate estimates of river discharge compared to those obtained from traditional empirical methods. Efforts were also made to improve the accuracy of estimates of discharge for poorly gauged rivers using remotely sensed data, hydrologic models, and ELQ.
Donghwan's Geosensing Systems Engineering & Sciences (GSES) advisor was Dr. Hyongki Lee. Congratulations, Donghwan!

Mexico and Central America Airborne Lidar Collection Campaign for Small- and Medium-Sized Projects
The National Center for Airborne Laser Mapping is announcing a call for expressions of interest from researchers with small- to medium-sized projects and budgets in Mexico and Central America for Spring 2020 (March–April). NCALM has received numerous inquiries from researchers with small projects in Mexico and Central America over the years. The size of these projects and their associated budgets make them economically and practically unfeasible. It is possible to survey small projects, and bring large benefits to the broader community, if several small projects within a country or region are grouped together and the mobilization costs are distributed. Project mobilization is also aided by larger projects funded by other sources. NCALM mapped seven small archaeological projects last year for the 2019 Mexico and Central America Lidar Collection Campaign. The work included projects in Mexico, Guatemala, Belize, and El Salvador.
NCALM has initially received expressions of interest for areas in Mexico, Belize, and Honduras. We are looking for additional projects to complement these sites. The smallest individual project budget that will be considered is $15,000. Exact coverage will be determined based on collection density, distance to airports, neighboring projects, and other factors. Send a short description of your project, potential budget, and KMZ of your area of interest if you have interest in participating in a community collection campaign. Projects must be research focused and can include, but are not limited to, archaeology, geology, hydrology, seismology, and ecology.
Please contact us for more information about the campaign and forward this announcement to other researchers that may have an interest in such data collection. The more projects that are organized together, the larger the areas that can be collected for individual projects. NCALM will start data collection in March–April 2020. We will begin requesting permits to fly and collect data for the respective countries in January 2020.
