Recursive Algorithm for L1 Norm Estimation in Linear Models
(American Society of Civil Engineers, 2011)L1 norm estimator has been widely used as a robust parameter estimation method for outlier detection. Different algorithms have been applied for L1 norm minimization among which the linear programming problem based on the ... -
Dedication of Highways in Texas
(American Society of Civil Engineers, 2011)This note discusses the methods for establishing highways in the State of Texas with the focus being on common-law dedication. In general, dedication is the intentional appropriation or donation of land or of an easement ... -
Reliability Analysis for a Robust M-Estimator
(American Society of Civil Engineers, 2011)The least-squares estimation exhibits a poor performance in the presence of gross errors. One of the typical approaches to control the influence of outliers is to use robust estimation techniques. The well-established ... -
Identification of Nearshore Wave Characteristics Using Robotic Total Stations
(American Society of Civil Engineers, 2010)A new geodetic method for accurate determination of nearshore wave characteristics is proposed. This method is based on a robotic total station set on stable position on the coast and aiming at a passive reflector mounted ... -
Deformation Detection in the GPS Real-Time Series by the Multiple Kalman Filters Model
(American Society of Civil Engineers, 2010)Global Positioning System (GPS) is widely used for monitoring some natural phenomena and man-made structures. The detection of the deformation epoch in real time is of great importance in these applications. This study is ... -
OPUS-RS Pair Points: Case Study
(American Society of Civil Engineers, 2010)Referencing small engineering surveys to the national spatial reference system (NSRS) presents advantages in terms of spatially coordinating infrastructure and facilitates the inclusion of the infrastructure in a geographic ... -
Statistical Properties of Strain and Rotation Tensors in Geodetic Network
(American Society of Civil Engineers, 2010)This article deals with the characteristics of deformation of a body or a figure represented by discrete points of geodetic network. In each point of geodetic network kinematic quantities are considered normal strain, shear ... -
Two Methods to Estimate the Spot Size of Terrestrial Laser Scanners
(American Society of Civil Engineers, 2010)This technical note presents the results of a study focused on the evaluation of laser beam divergence and its effect on the spot size of terrestrial laser scanners. For this purpose, experiments were accomplished using ... -
Noniterative Approach for Solving the Indirect Problems of Linear Reference Frame Transformations
(American Society of Civil Engineers, 2010)A linear transformation, including a similarity model and an affine model, plays an important role in reference frame transformation problems. It establishes geometric relations between different reference frames by adopting ... -
Detection of Terrain Morphologic Features Using GPS, TLS, and Land Surveys: “Tana della Volpe” Blind Valley Case Study
(American Society of Civil Engineers, 2010)The aim of this article is to review the potentiality and reliability of the integrated usage of global positioning system (GPS), terrestrial laser scanner (TLS), and total station survey measurements in the geomorphologic ... -
Interpolating Surface Gravity Data for Assessing the Accuracy of a Ground Inertial Navigation System/Global Positioning System Gravimetric System
(American Society of Civil Engineers, 2010)High-resolution gravity data are efficiently collected by using a ground-vehicle-based inertial navigation system/global positioning system (INS/GPS) gravimetric system due to its closeness to the terrain and relatively ... -
Propagation of an Unmodeled Additive Constant in Range Sensor Observations
(American Society of Civil Engineers, 2010)The rangefinder offset, additive constant or zero error is the most basic systematic error affecting the accuracy range measurements. Recent investigations of different systems that feature range measurement have shown ... -
Rigorous Estimation of Local Accuracies
(American Society of Civil Engineers, 2010)This technical note introduces a rigorous calculation of “local accuracies.” The term local accuracies refers to the relative error between two arbitrary points (uncertainty of one point with respect to the other), expressed ... -
Rotation- and Translation-Free Estimations of Symmetric, Rank-Two Tensors with a Case Study in LIDAR Surveying
(American Society of Civil Engineers, 2010)An eigenparameter analysis plays an important role in varied fields where a symmetric tensor is involved. This technique allows one to investigate the principal behaviors (i.e., magnitudes and orientations) of a physical ... -
Modern Determination of Vertical Deflections Using Digital Zenith Cameras
