Enhancement of height system for Malaysia using space technology: the study of the datum bias inconsistencies in Peninsular Malaysia [PDF]

open access: yes, 2003
The algorithm for orthometric height transfer using GPS has been widely presented. Its practical limitations are mostly due to datum bias inconsistencies and lack of precise geoid.

6326 Shades of Georeferencing BIM - Low distortion projections (LDP) for the German Railway [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Beside smart Information Management, Building Information Modeling (BIM) focuses on three-dimensional planning and model coordination. However, 3D CAD/BIM software does not conceptualize geodetic coordinates, which causes systematic deviations between ...

The Canadian Geodetic Vertical Datum of 2013 (CGVD2013)

open access: yesGeomatica, 2016
The Canadian Geodetic Vertical Datum of 2013 (CGVD2013) is the first major update to the vertical datum in Canada in almost 100 years. Canada is not only moving to a new vertical datum, but it is also using a modernized approach to realize it. The modernization of the height reference system is necessary to make it compatible with Global Navigation ...

Statistical Properties of Strain and Rotation Tensors in Geodetic Network [PDF]

open access: yes, 2010
This article deals with the characteristics of deformation of a body or a figure represented by discrete points of geodetic network. In each point of geodetic network kinematic quantities are considered normal strain, shear strain, and rotation. They are
