Real-Time Precise Point Positioning in NAD83: Global and Regional Broadcast Corrections Compared
- Abstract: P. J. G. Teunissen, L. Huisman, and C. Hu Real-time Precise Point Positioning (PPP) is possible by the availability of the real-time satellite orbit and clock corrections to broadcast ephemeris, the real-time Broadcast Corrections (BC). The real-time BCs are currently available in global as well as in regional reference frames. In this cont ...

Application of the Sign-Constrained Robust Least Squares Method to Surveying Networks
- Abstract: Mevlut Yetkin and Mustafa Berber The Least Squares (LS) method is highly susceptible to outlying observations. For this reason, various types of robust estimators have been developed; for example, M-estimators. In this paper, we propose to use the sign-constrained robust least squares (SRLS) method in surveying networks utilizing t ...

Road Construction Earthwork Volume Calculation Using Three-Dimensional Laser Scanning
- Abstract: Kerry T. Slattery, Dianne K. Slattery, and James P. Peterson Terrestrial laser-scanning (TLS) technology can be used to create a detailed model before and after construction to determine earthwork quantities. Cost-effective implementation of this technology requires that field operations are planned to efficiently acquire sufficient scan data and that data pr ... [J. Surv.

Estimating 3D Volume Using Finite Elements for Pit Excavation
- Abstract: B. Mukherji In studies related to ground excavations, glaciers, human brains, or many other branches of science, a need to know often arises regarding the volume of an irregularly shaped object or region in 3D space. An approach using finite elements offers a closed form solution that can accommodate uneven spa ... [J. Surv. Eng. doi:10.1061/(ASCE)SU.1943-5428.0000059] published Tue May 8, 2012.

Structural Deflection Measurement with a Range Camera
- Abstract: Derek D. Lichti, Sonam Jamtsho, Sherif Ibrahim El-Halawany et al. Range cameras offer great potential for the measurement of structural deformations because of their ability to directly measure video sequences of three-dimensional coordinates of entire surfaces, their compactness, and their relatively low cost compared with other active imaging technologies such a ...

Rejuvenating Pre-GPS Era Geophysical Surveys Using The National Map
- Abstract: Tom Shoberg, Paul R. Stoddard, and Michael P. Finn Old geophysical surveys [preGlobal Positioning System (GPS)] stand as valuable, largely untapped sources of scientific data. If data from these surveys were in a format that had reasonable accuracy, availability, and ease of access, they could be more widely used. In this paper, a pre-GPS survey is ... [J. Surv.

Power of Global Test in Deformation Analysis
- Abstract: Cuneyt Aydin There are two kinds of global test procedures in deformation analysis; chi-test (CT) and F-test (FT). This study discusses their power functions. The CT is more powerful than the other one in an analytical point of view. However, it requires an accurate knowledge on the a priori variance of unit wei ... [J. Surv.

Weakly Multicollinear Datum Transformations

However, in many cases, the available geodetic network configuration with respect to the estimation model is insufficient due to the physical and financial limitations. For the case of estimating the datum transformati ... [Journal of Surveying Engineering doi:10.1061/(ASCE)SU.1943-5428.0000086] posted Sat Mar 10, 2012.

Time Correlation in GNSS Positioning over Short Baselines
