GNSS-Based Verticality Monitoring of Super-Tall Buildings
Applied Sciences, 2018 In the construction of super-tall buildings, it is rather important to control the verticality. In general, a laser plummet is used to transmit coordinates of reference points from the ground layer-by-layer, which can effectively control the verticality ...

Modern Determination of Vertical Deflections Using Digital Zenith Cameras [PDF]
, 2010 At the beginning of the 21st century, a significant technological change took place in geodetic astronomy. In Zurich and Hannover, digital zenith camera systems were developed based on digital imaging sensors (charge-coupled device) that strongly ...

On the determination of the deflection of the vertical by satellite altimetry
Marine Geodesy, 1984 Abstract With the advent of satellite altimetry it has become possible to estimate the height of the marine geoid above the ellipsoid to an accuracy of better than 1 m. At a crossover of a satellite's ascending and descending tracks, altimeter data can be used to obtain two linearly independent estimates of the geoid's horizontal gradient.

Modelling of reinforced concrete slab deflections at service loading [PDF]
, 1994 Includes bibliographical references.Deflection under service loading is an important aspect of reinforced concrete slab design. Under-design can cause large deflections which can be expensive to repair, if at all possible.

Using the rapid graphic method in determining the vertical deflections in High Tatras [PDF]
Acta Montanistica Slovaca, 2005 In mountains regions, the effect of vertical deflections appreciably exceeds the accuracy of most geodetic measurements and causes systematic errors of some cm per km at steep sightings.

ESTIMATION OF VERTICAL DEFLECTIONS IN CONCRETE BEAMS THROUGH DIGITAL CLOSE RANGE PHOTOGRAMMETRY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Deformation monitoring, and in general structural health monitoring, of civil infrastructure systems is important in terms of both safety and serviceability. Traditionally, large structures have been monitored using surveying techniques, while fine-scale
