Comparisons of Ground-Based and Building-Based CORS: A Case Study in the Region of Puerto Rico and the Virgin Islands
(American Society of Civil Engineers, 2016)This study investigated long-term observations from three pairs of closely spaced, continuously operating reference stations (CORS): STVI and VITH (2008–2014, 0.6 km apart), BYSP and PRHL (2008–2014, 3.2 km apart), and ... -
Morphological Analysis for Architectural Applications: Comparison between Laser Scanning and Structure-from-Motion Photogrammetry
(American Society of Civil Engineers, 2016)Terrestrial laser scanning (TLS) and structure-from-motion photogrammetry (SfM) can both provide dense and accurate point clouds. Therefore, they can be used to perform a morphological analysis of the façades of a masonry ... -
A Practical Quality Index for the Applied Helmert Transformation
(American Society of Civil Engineers, 2016)The Helmert transformation is used in different procedures in geodesy, photogrammetry, and in general in geomatics. The assessment of the accuracy of the transformation, and in particular of the transformed coordinates, ... -
First-Order Design of GPS Networks Using Particle Swarm Optimization
(American Society of Civil Engineers, 2016)This paper discusses the optimization problem of first-order design (FOD) of global positioning system (GPS) networks. The classical least-squares technique was revised for the formulation of the objective function of FOD ... -
First Steps Using Two GPS Satellites for Monitoring the Dynamic Behavior of a Small Concrete Highway Bridge
(American Society of Civil Engineers, 2016)This work presents the results of global positioning system (GPS) data processing using the phase residuals method (PRM)—L1 carrier phase from two satellites—to monitor the dynamic behavior of a small concrete bridge. The ... -
A Closed-Form Solution for Coarse Registration of Point Clouds Using Linear Features
