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 ...

How Significant is the Dynamic Component of the North American Vertical Datum?

open access: yesJournal of Geodetic Science, 2012
One of the main current geodetic activities in North America is the definition and establishment of a geoid-based vertical datum that will replace the official CGVD28 and NAVD88 datums in Canada and the USA, respectively.

Treatment of Geodetic Leveling in the Integrated Geodesy Approach [PDF]

open access: yes, 1988
Integrated geodesy is a method which models a wide variety of surveying measurements in terms of geometric positions and the earth's geopotential. Using heterogeneous data, both geometric and gravimetric quantities are simultaneously estimated by a least-

Geodetic datums of the Italian cadastral systems

open access: yes, 2011
The geodetic datum, and its possible descriptions, of the Italian cadastral networks are analyzed, in order to provide a solution to fit the cadastral sheets to modern map contents and grids, using just their corner crosshair data. Analyzing the extension of the Genova 1902 datum to the whole Italian territory, it occured that the transformation error ...
