Digital Surface Models for GNSS Mission Planning in Critical Environments
(American Society of Civil Engineers, 2014)Global Navigation Satellite System (GNSS) surveys performed in critical environments (e.g., urban canyons, mountainous areas, or areas of dense vegetation) usually suffer from a lack of satellite coverage as a result of ... -
Univariate Approach for Detecting Outliers in Geodetic Networks
(American Society of Civil Engineers, 2014)In geodetic networks, observations are measured repetitively, and the mean values of these observations are used for network adjustment, outlier detection, deformation analysis, etc. These repetitive observations are ... -
Practical Formulas for the Refraction Coefficient
(American Society of Civil Engineers, 2014)Knowledge of the actual refraction coefficient is essential in leveling surveys and precise electromagnetic distance measurement reduction. The most common method followed by the surveyor for its determination is based on ... -
Efficient Between-Satellite Single-Difference Precise Point Positioning Model
(American Society of Civil Engineers, 2014)This paper describes a new model for precise point positioning (PPP), which overcomes the drawbacks of existing PPP models. This model is based on between-satellite single-difference (BSSD), which cancels out the receiver ... -
On Deflection of the Vertical Components and Their Transformations
(American Society of Civil Engineers, 2014)The deflection of the vertical is an important parameter that combines both physical (astronomic) and geometric (geodetic) determined quantities. This paper introduces an alternative didactic approach based on rotations ... -
Time-Variant Adjustment for a Level Network
(American Society of Civil Engineers, 2014)It has been routine work to determine the elevations of points on Earth’s surface for a wide range of purposes. However, surveyors are now facing new challenges because of the increasing demand for high-quality measurements ... -
Determination of the Geometric Form of Hierapolis Theater in Pamukkale, Turkey
(American Society of Civil Engineers, 2014)This work addresses the issue of fitting a geometrical shape to the Hierapolis theater near the city of Denizli, Turkey. The aim of the study was to determine the geometrical shape of the theater that would best fit the ... -
Simple Solution to the Three Point Resection Problem
(American Society of Civil Engineers, 2013)The paper presents a simple method of finding the solution to the planar three point resection problem. The main concept leading to the solution is based on an idea of two intersecting circles (which is not new in the ... -
Feature Conjugation for Intensity-Coded LIDAR Point Clouds
(American Society of Civil Engineers, 2013)Feature conjugation is a major task in modern-day spatial analysis and contributes to efficient integration across multiple data sets. In this study, an efficient approach that utilizes the intensity information provided ... -
Least-Squares Variance Component Estimation Applied to GPS Geometry-Based Observation Model
(American Society of Civil Engineers, 2013)To achieve the best linear unbiased estimation of unknown parameters in geodetic data processing a realistic stochastic model for observables is required. This work is a follow-up to work carried out recently in which the ... -
Using OPUS for Measuring Vertical Displacements in Houston, Texas
(American Society of Civil Engineers, 2013)The Houston area has been suffering from subsidence for several decades. Therefore, continuously operating reference stations (CORS) in this area may have experienced considerable vertical displacements. The Online Positioning ... -
