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...

Accuracy assessment of LiDAR point cloud geo-referencing

Creator:: Williams, Keith E.
Abstract:: Three-dimensional laser scanning has revolutionized spatial data acquisition and can be completed from a variety of platforms including airborne (ALS), mobile (MLS), and static terrestrial (TLS) laser scanning. MLS is a rapidly evolving technology that provides increases in efficiency and safety over static TLS, while still providing similar levels of...

Numerical Characterization and Modeling Uncertainty of Frame-Spine and Frame-Spine-FLC Full-Scale Specimens Tested at E-Defense Shake-Table

Creator:: Astudillo, Bryam
Abstract:: The characterization of the seismic performance of structures relies on numerical simulations. However, estimates of seismic response are subject to various sources of uncertainty, including modeling uncertainty. This research estimated the response of two full-scale structural specimens composed of a moment resisting frame, elastic spines, and force-limiting connections (FLC), which...

Radar and Optical Remote Sensing of Submesoscale Frontal Features

Creator:: Simpson, Alexandra J.
Abstract:: The coastal region is home to many types of surface fronts that exist on a submesoscale (1-10 $km$). While in situ observations capture point or transect observations of frontal behavior subsurface, their complex spatial patterns can be well-captured using remote sensing techniques, which provide synoptic views of the ocean surface...

Optimal sensor placement for measuring operating speeds through curves on rural two-lane highways

Creator:: Mecham, Megan E.
Abstract:: Operating speed is one of the best performance measures that can tell transportation agencies how well or how poorly the transportation system is functioning. Fluctuating operating speeds often mean there is a design flaw or something about the physical road design that violates drivers' expectations. A primary example of this...

Of Planes and Plumblines: Map Projections and Differential Leveling in a GNSS-based 3D Geodetic Framework

Creator:: Dennis, Michael L.
Abstract:: Modern geospatial data are frequently represented in some type of three-dimensional (3D) coordinate system, for example geodetic latitude, longitude, and ellipsoid height (φ, λ, h) derived from Global Navigation Satellite Systems (GNSS). But for engineering and surveying work, φ, λ, h coordinates are usually converted to a topocentric system consisting...

Remote Sensing Tools for Evaluating Climate Change Impacts in Coastal Environments

Creator:: Herrmann, Joan F.
Abstract:: Climate change has pervasive impacts on Earth’s diverse ecosystems. Observed and projected effects that impact coastal environments pose unique challenges. Coastal regions provide numerous ecosystem services (e.g., fisheries, nursery habitats, erosion control, and water filtering and detoxification), house 40% of the US population, and contribute to 58% of the national...

A Multivariate Comparison of Drone-Based Structure from Motion and Drone-Based Lidar for Dense Topographic Mapping Applications

Creator:: Simpson, Chase H.
Abstract:: Unmanned aircraft systems (UAS), also known as drones, are an increasingly popular method of collecting surveying and mapping data. Two common drone-based mapping techniques are lidar and structure from motion (SfM) photogrammetry, and a frequently-heard (yet nearly impossible to answer) question is: “which is better?” The most common metric for...

Evaluation of desktop learning modules in civil engineering classrooms to promote inductive and interactive learning

Creator:: Buker, Kamilah E.
Abstract:: Students in undergraduate engineering programs typically do not synthesize content learned from disparate course work until the end of their final terms of college. As an example, in undergraduate civil engineering programs, transportation engineering concepts (e.g., geometric alignment, asphalt design procedures) and geotechnical engineering concepts (e.g., shear strength of soils,...

Efficient Topobathymetric Mapping and 3D Spatial Analysis of Estuaries Using Multi-Platform, Multi-Temporal Data

Creator:: Lambert, Selina E.
Abstract:: Frequent 3D spatial mapping of estuaries is critical to understanding and modeling changes that can impact ecological health (e.g., water quality) and ecosystem services (e.g., aquaculture, nutrient cycling, and shoreline stabilization). However, obtaining accurate, repeat topobathymetric data for estuaries is a major challenge. Because shallow estuaries are typically not used...
