Ben Wilkinson

Assistant professor

Dr. Wilkinson is an assistant professor in the Geomatics Program at the University of Florida, and is the principal investigator for GMAP Labs Regional Geospatial Modeling project. Dr. Wilkinson is interested in 3D scene reconstruction using photogrammetric techniques as well as data adjustment, fusion, and uncertainty estimation. He is coauthor of the textbook Elements of Photogrammetry with Applications in GIS, Fourth Edition.

Amr Abd-Elrahman

Associate professor

Dr. Abd-Elrahman is an Associate Professor of Geomatics at the University of Florida’s Gulf Coast Research and Education Center. He received his BS in Civil Engineering and MS in Digital Mapping. He acquired his PhD in Civil Engineering-Geomatics with a minor in Computer Engineering. Dr. Abd-Elrahman has been involved in natural resource management and precision agricultural research projects utilizing unmanned aerial system imagery since early 2000s. His research projects involved wetland land cover classification, invasive plant detection, and modeling crop stress using pixel- and object-based image analysis and machine learning techniques.

H. Andrew Lassiter

Postdoctoral associate

Andrew is a postdoctoral researcher for the Regional Geospatial Modeling project. Andrew began his UAS research in 2016, joining UF UAS Research Program to assist in the collection and processing of hyperspectral data. Since then, his focus has extended to include the collection of 3D data using both lidar and structure from motion (SfM) photogrammetry. He has developed sensor modeling software for lidar and photogrammetric data collection to determine best practices for UAS mission planning. His past research also includes semi-automated estimation of key traits of trees from point clouds, such as stem count, stem height, DBH, and AGB.

In addition to instructing Forest Mensuration in 2019, Andrew has served as a teaching assistant at UF since 2013 for the courses of Advanced Photogrammetry, Forest Resource Information Systems, Spatial Measurement Systems, and Geomatics. Prior to that, Andrew worked as a survey technician in Panama City, Florida, in both the public and private sectors.

Ali Gonzalez Perez

Ph.D. student

Mr. Ali Gonzalez Perez is a Ph.D. student in the geomatics program at UF with BS and MS degrees in Mining. Mr. Gonzalez is a professional surveyor and mapper in the State of Florida and a licensed remote pilot. He has a great passion towards using drones in natural resource management applications. Currently Ali’s research focuses on characterizing coastal habitat using UAS LiDAR, multispectral and hyperspectral imagery. Ali lives in a countryside neighborhood in Polk County, Florida, and his passion hobby is working in creating his own sustainable edible yard with semitropical edible plants, fruits, herbs and tubers.

Sanduni Disanayaka Mudiyanselage

Ph.D. student

I am a PhD student in the Geomatics program here at UF. I am originally from Sri Lanka and moved to Florida in 2018. I earned a BS degree in Civil Engineering from University of Moratuwa, Sri Lanka. Owing to my passion to study about the ever-so-dynamic coastal environment, I completed her master’s in Coastal Engineering at TU Delft in the Netherlands.

The field of geospatial analysis fascinates me as it provides a robust tool to study coastal morphology and ecological habitats which will facilitate sustainable solutions to many coastal zone issues. My current research work focuses on effective use of remote sensing techniques to assess the coastal morphology with the use of machine learning techniques. I incorporate multispectral satellite imagery and topo-bathy lidar data in analyzing diverse coastal regions.

In my free time, I love to travel to scenic/historical places and enjoy with my precious little family.

Carter Kelly

M.Sc. student

Mr. Kelly is a graduate student in the Geomatics Program, working on his master’s thesis. He is currently studying rigorous accuracy assessments of lidar scanners, establishing a holistic understanding of sensor capabilities and their impact on collected data. He holds a BS from West Point in GIS and a graduate certificate from the University of Florida in Geospatial Analysis. Carter is currently serving as an armor officer in the Army, and will be assuming an instructor positon at West Point post-thesis. Prior to attending the University of Florida, Carter has been stationed at Fort Benning, GA, Fort Carson, CO, and Fort Polk, LA, training and leading reconnaissance units with one overseas tour in Kuwait and Jordan.

Robert Moon

Ph.D. student

Mr. Moon is a graduate student in the geomatics program with an interest in remote survey for Earth Science and Intelligence applications. He served as an intelligence officer in the Marine Corps managing analysis and collection operations. He holds undergraduate degrees in Economics from University of Florida and Earth Science from Columbia University. His previous academic work includes utilizing structure from motion to analyze lava flow morphology in Chile and hyperspectral imagery for surface mineral identification.

Connor Bass

M.Sc. student

Mr. Bass is a master’s non-thesis studying in the geomatics program and specializing in Geospatial Analysis. He is an FAA Part 107 certified pilot with land and sUAS surveying experience. His current research explores semi-automated classification of water returns in UAS lidar point clouds.
