Compilation of a Map of Recent Vertical Crustal Movements in Eastern Canada Using Geographic Information System
(American Society of Civil Engineers, 2006)In this paper, we use geographic information system as a useful tool in compiling vertical crustal movement (VCM) over Eastern Canada. For modeling linear VCM, we employ tide gauge records and precise releveled segments, ... -
Deflection of the Vertical Components from GPS and Precise Leveling Measurements in Hong Kong
(American Society of Civil Engineers, 2006)Deflection of the vertical components of a station located in Hong Kong are estimated from the ellipsoidal height differences inferred from global positioning system (GPS) measurements and orthometric height differences ... -
Robustness Analysis of Two-Dimensional Networks
(American Society of Civil Engineers, 2006)After geodetic networks are established, relevant measurements are made and point coordinates are estimated by the least-squares method. However, the least-squares method does not give any information about the robustness ... -
Determining Free Flight Performance by Surveying Engineering Techniques
(American Society of Civil Engineers, 2006)Time aloft and distance traveled in free flight with a paraglider are determined by three factors: weather conditions, pilot skill, and paraglider performance. The latter factor can be represented in a performance curve. ... -
Single Epoch Kinematic GPS Positioning Technique in Short Baseline
(American Society of Civil Engineers, 2006)Resolving for integer phase ambiguities is an important issue of satellite surveying. In general ambiguity resolution techniques, observations made at tens of continuous epochs are required. These techniques usually fail ... -
Use of Fresnel Enantiomorphic Diffraction in Surveying Laser Methods
(American Society of Civil Engineers, 2006)This paper is a summary of an experiment using Fresnel enantiomorphic diffraction in geodetic laser methods. In this study, results from the analysis of a large data set made possible the determination of the degree of ... -
Solving an Inverse Problem of a Meridian Arc in Terms of Computer Algebra System
(American Society of Civil Engineers, 2006)In terms of computer algebra systems, an inverse problem of a meridian arc is discussed in two somewhat different ways in this paper. One is the conventional power series method and the other is a Hermite interpolation. ... -

Local Geoid Improvement Using GPS and Leveling Data: Case Study
(American Society of Civil Engineers, 2006)National leveling height networks have recently been set up in Taiwan, and global positioning system (GPS) observations were carried out at the benchmarks of the networks. The purpose of this paper is to develop an improved ... -
Base Station Establishment Using Multiple Global Positioning Satellite Stations and Free Net Approach
(American Society of Civil Engineers, 2006)One of the possible uses of the global positioning satellite permanent stations is to use them as a datum reference when a new base station is established in a geodetic or surveying project. However, the actual procedure ... -
Assessment of Dynamic Measurement Accuracy of GPS in Three Directions
(American Society of Civil Engineers, 2006)Global positioning system (GPS) technology is an emerging tool for measuring and monitoring both static and dynamic displacement responses of large civil engineering structures to gust winds. The accuracy of dynamic ... -
Determination of Point Displacements in the Geodetic Network
(American Society of Civil Engineers, 2006)This paper describes the procedure for testing the statistical significance of point displacements in the geodetic network as the intermediate stage between the adjustment of respective epochs measurements and an in-depth ... -
Evaluation of the Movements of the Dam Embankments by Means of Geodetic and Geotechnical Methods
(American Society of Civil Engineers, 2006)In this study, the evaluation of the surface movements that took place after the completion of an earth fill dam constructed by staged construction have been evaluated by means of geodetic and geotechnical methods. Horizontal ... -
Geographic Information Systems/National Elevation Data Route Mileage Verification
(American Society of Civil Engineers, 2006)Maintaining the nation’s roads and highways is a critical national infrastructure activity. To do so requires that accurate inventories of roadway features as well as the roadway network itself be maintained. This paper ... -
Long-Range Geoid Testing by GPS-Leveling Data in Turkey
(American Society of Civil Engineers, 2006)A long-range geoid testing procedure is presented using a geometrical geoid profile, which extends in an approximate north–south direction between the Mediterranean and the Black Sea. Along the first-order leveling line ... -
Coordinate Transformation between Two Geodetic Datums of Taiwan by Least-Squares Collocation
(American Society of Civil Engineers, 2006)Recently, the new Taiwan geodetic datum 1997 (TWD97) based on the Global Positioning System measurements has been established. Compared to the old geodetic datum, namely the Hu-Tzi-Shan datum, the TWD97 datum is more ... -
Measuring System for Cracks in Concrete Using Multitemporal Images
(American Society of Civil Engineers, 2006)In this paper we discuss a semiautomatic measuring system that can extract images of cracks in the surface of concrete from multitemporal images. An accuracy assessment and analysis of the relationship between expansion ... -
Strategic Decision Analysis for Selection of Landfill Sites
(American Society of Civil Engineers, 2006)This paper presents a methodology used to assess and select areas for landfills implantation in the city of Cachoeiro de Itapemirim–ES (Espírito Santo State), Brazil, using multicriteria analysis and geographical information ... -
Global Positioning System Detection of Minuteman II Launch and Positioning of Launch Site
(American Society of Civil Engineers, 2005)In this paper, global positioning system (GPS) data collected by seven permanent GPS stations of Southern California Integrated GPS Network during the launch of the long-range Minuteman II missile from Vandenberg Air Force ... -
Trilateration Computer Program
(American Society of Civil Engineers, 2005)A computer program has been developed for the reduction of trilateration data. The program is general in that it will handle any control figure that a user might specify. Data validation is a key feature of the program. ...
