Pratikshya Regmi, a second-year MANTIS master student in the Geospatial Systems Engineering program, presented her research at the International Federation of Surveyors (FIG) conference in Orlando FL, between May 28 and June 1, 2023.

Summary of Project/Presentation:

This project, referred to as Campus UAS, employed a small uncrewed aircraft system (UAS) platform equipped with RGB cameras for surveying and mapping campus infrastructure and facilities at Texas A&M University-Corpus Christi (TAMU-CC) since 2014. Pratikshya’s presentation began by highlighting the necessity of survey data and the benefits of implementing UAS for aerial surveys instead of using the traditional ground-based methods employed at the university. It then elaborated on the genesis of UAS platforms used at the university from 2014 to the present day including the evolution from indirect georeferencing using a ground control point network to more direct georeferencing alternatives using onboard global navigation satellite system (GNSS) receivers equipped with post-processed kinematic (PPK) capabilities/corrections. In addition, she discussed the benefits of integrating UAS products with traditional land surveying methods to obtain survey-grade accuracy from photogrammetric products derived from UAS. Lastly, attention was brought to diverse applications of UAS survey products beyond facility management and infrastructure planning and dissemination methods.

Overall, her work provided a comprehensive overview of the progression of UAS mapping technology for geospatial data acquisition in support of facilities monitoring at TAMU- CC.
