CONSTRUCTION THEORY AND NOISE ANALYSIS METHOD OF GLOBAL CGCS2000 COORDINATE FRAME [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
The definition, renewal and maintenance of geodetic datum has been international hot issue. In recent years, many countries have been studying and implementing modernization and renewal of local geodetic reference coordinate frame.

A computational model of the referential semantics of projective prepositions [PDF]

open access: yes, 2006
In this paper we present a framework for interpreting locative expressions containing the prepositions in front of and behind. These prepositions have different semantics in the viewer-centred and intrinsic frames of reference (Vandeloise, 1991).

Disentangling the External Reference Frames Relevant to Tactile Localization

open access: yesPLOS ONE, 2016
Different reference frames appear to be relevant for tactile spatial coding. When participants give temporal order judgments (TOJ) of two tactile stimuli, one on each hand, performance declines when the hands are crossed. This effect is attributed to a conflict between anatomical and external location codes: hand crossing places the anatomically right ...

Localization and reference frames in κ -Minkowski spacetime [PDF]

open access: yesPhysical Review D, 2019
We study the limits to the localizability of events and reference frames in the $κ$-Minkowski quantum spacetime. Our main tool will be a representation of the $κ$-Minkowski commutation relations between coordinates, and the operator and measurement theory borrowed from ordinary quantum mechanics.

Houston16: A stable geodetic reference frame for subsidence and faulting study in the Houston metropolitan area, Texas, U.S.

open access: yesGeodesy and Geodynamics, 2019
Houston, Texas, is one of the earliest regions to employ continuous GPS technology for land subsidence monitoring. Currently, there are over 200 permanent GPS stations located in the greater Houston area.

From a Somatotopic to a Spatiotopic Frame of Reference for the Localization of Nociceptive Stimuli

open access: yesPLOS ONE, 2015
To react efficiently to potentially threatening stimuli, we have to be able to localize these stimuli in space. In daily life we are constantly moving so that our limbs can be positioned at the opposite side of space. Therefore, a somatotopic frame of reference is insufficient to localize nociceptive stimuli.
