Application of GNSS for Vertical Reference Determination

Creator:: Kim, Su-Kyung
Abstract:: Vertical datum is a reference system used for specifying the elevation of specific points on or near the Earth. Precise and accurate definition and realization of vertical references are, therefore, crucial to ensure consistency between height measurements. The vertical datums can be divided into two categories: 1) vertical geodetic datums...

Evaluating Methods of Aligning Real-Time GNSS Networks to the National Spatial Reference System

Creator:: Ohene, William
Abstract:: Aligning Real-Time Networks (RTNs) with the National Spatial Reference System (NSRS) is crucial to ensure accuracy, consistency, interoperability, and long-term data integrity for geospatial applications. However, the effectiveness of different alignment methods as well as the need for monitoring approaches to maintain alignment consistency with the NSRS have not yet...

An Efficient Workflow and Accuracy Assessment for ICESat-2 and Multispectral Imagery Fusion for Bathymetric Mapping

Creator:: Babbel, Benjamin J.
Abstract:: Interest in mapping bathymetry from multispectral satellite imagery has grown steadily since the 1970s. Notwithstanding the significant advancements made during this time, one limitation is that the group of algorithms collectively referred to as Satellite Derived Bathymetry (SDB) generally require “seed depths,” hindering their use for areas lacking reliable reference...

Automated Monitoring of Modular Construction Factories using Computer Vision

Creator:: Panahi, Roshan
Abstract:: Modular construction is increasingly seen as an efficient construction method in terms of time, cost, and energy. The full realization of these advantages partly relies on the efficiency of the production process inside the modular factories, which currently rely on tedious manual monitoring methods or expensive automated techniques. As a...

Investigation of Multi-constellation RTK GNSS Survey Productivity and Coordinate Accuracy

Creator:: Jamieson, Marian H.
Abstract:: This study evaluates the productivity and accuracy of surveys completed with single-base real-time kinematic (RTK) Global Navigation Satellite Systems (GNSS) using four different GNSS constellation combinations: (1) GPS-only, (2) GPS+GLONASS, (3) GPS+Galileo+BeiDou, and (4) GPS+GLONASS+Galileo+BeiDou. For this comparison, we set up a test site consisting of 20 stations ranging with...

Influence of Uncertainties in Terrestrial Laser Scanning on Structural Reliability and Bridge Load Rating

Creator:: Loving, Carly K.
Abstract:: To ensure the safety of the nation’s bridges, the National Bridge Inspection Standards (NBIS) require all bridges to undergo routine load rating analyses to assess their structural capacity. Accurate geometric information for each structure is necessary for load rating analyses. This information is typically ascertained from as-built plans. Still, when...

Performance of ionospheric maps in support of long baseline GNSS kinematic positioning at low latitudes

Creator:: Park, J., Sreeja, V., Aquino, M., Cesaroni, C., Spogli, L., Dodson, A., and De Franceschi, G.
Abstract:: Ionospheric scintillation occurs mainly at high and low latitude regions of the Earth and may impose serious degradation on GNSS (Global Navigation Satellite System) functionality. The Brazilian territory sits on one of the most affected areas of the globe, where the ionosphere behaves very unpredictably, with strong scintillation frequently occurring...

Seismic performance of reinforced concrete bridge columns constructed with grade 80 reinforcement

Creator:: Link, Tim B.
Abstract:: The research presented in this thesis assessed the use of high strength steel (HSS) reinforcement for use in reinforced concrete (RC) bridge columns. HSS is not currently allowed in reinforced concrete bridge columns due to a lack of information on the material characteristics and performance information when used in RC...

Paving the way for terrestrial laser scanning assessment of road quality

Creator:: Chin, Abby
Abstract:: With the growing trend in use of 3D laser scanning technology for data collection, it is important to study the various potential applications of this revolutionary technology. One such application is the measurement of road roughness at both large and small scales. At larger extents, terrestrial laser scanning (TLS) is...
