Mexico and Central America Focus

Planning for the 2019 Mexico and Central America Lidar Collection Campaign for Small- and Medium-Sized Projects is ongoing. Currently there are 14 committed projects in Mexico, Belize, Guatemala, El Salvador, and Honduras. NCALM has applied for a temporary export license of the mapping equipment and is working with project PIs to acquire the necessary permits for each location.

NCALM is enthusiastic about this first international small-project campaign and is eager to begin the data collection portion. Principal Investigators can expect regular updates through email as we coordinate and arrange assistance for each project. We anticipate beginning to map in April/May.

The due date for 2018 Seed Project proposals has been extended until Friday, February 1, 2019. Due to research community requests, students will be provided additional time to apply for a seed project grant. This will allow for more and better submissions from graduate students. See the program announcement below:

The National Center for Airborne Laser Mapping invites proposals from graduate students seeking airborne lidar data (up to 40 km2) for use in research toward an M.S. or Ph.D. degree. For background information and a complete guideline for submitting a proposal, see the Seed Proposals and Format Guidelines pages. The proposal submission period is Thursday, September 13, 2018–Friday, February 1, 2019. For more information, contact ncalm [at] egr.uh.edu (subject: Seed%20Proposal%20Inquiry) or call (832) 842-8881.

Ekhtari Defends Ph.D. Dissertation

Ph.D. candidate Nima Ekhtari defended his dissertation titled, "Land Cover and Impervious Surface Mapping Using Multispectral Airborne Laser Scanner Data." High-resolution, multispectral (multiwavelength) laser scanner data were used to classify land cover, using machine learning, into diverse classes for impervious surface mapping and urban change studies. The dissertation proposes two methods to mitigate the influence of multi-echo effect on the spectral information of ALS returns. Hybrid intensity correction schemes were also devised and tested to improve classification accuracy. The final impervious surface map showed that the approach had higher accuracies compared to a similar map created from a hyperspectral passive imager, demonstrating the advantage of multispectral ALS data for automated, high-accuracy, high-resolution impervious surface mapping.

Nima’s Geosensing Systems Engineering & Sciences (GSES) advisor was Dr. Craig Glennie. He is currently working at CobbFendley & Associates as a GIS Analyst. Congratulations, Nima!

Laura Ann Murphy

Faculty, staff, and students at University of Houston’s National Center for Airborne Laser Mapping are deeply saddened by the passing of our friend and colleague Laura Ann Murphy. Laura was not only essential to our day-to-day research and teaching efforts, but she went above and beyond to ensure that we were happy and doing well. From a simple M&M dispenser that she kept at her desk so we had a sweet moment when we stopped to talk to her, to her famous pineapple upside-down cake and Irish beef and Guinness stew that she often prepared for our pot-lucks or celebrations, to the many lunches, dinners, and outings she organized for staff, students, and visitors, to the unforgettable moments she delighted and entertained us through singing, she has left us with countless memories. Laura was not only special and caring to the people she knew, but she was kind and helpful to those in need that she did not know. When Hurricane Harvey hit Houston last year, she was one of the first people to organize food, clothing, and supplies collection and delivery for her immediate and city-wide neighbors.

We have lost not only a coworker, but we have lost an important part of our collective spirit. We are certain that she would like us to keep moving forward, to continue to do good for science and our communities, and to put a smile on our friends’, families’, and neighbors’ faces. As we miss her, we also celebrate her life, her accomplishments, and the joy and positive examples she brought to our lives. Below we share photos of a few of these special moments with which she enriched our lives.

Researchers with the National Center for Airborne Laser Mapping used the center's lidar-equipped plane to map the permafrost in Antarctica.

Lidar Mapping Has Also Yielded Other Earth Science Discoveries

 

The National Center for Airborne Laser Mapping is best-known for its headline-grabbing work in archeology – the 2016 discovery of previously unknown ruins of a complex Maya settlement in the Guatemalan jungles, undocumented settlements from an ancient civilization in Honduras uncovered in 2012, and detailed mapping of more than a dozen other settlements in Mexico and Central America.
