Abstract
Techniques for 3D mapping are maturing. At the
same time the need for 3D data is increasing. This has pushed national
(and regional) mapping agencies (NMAs) to consider extending their
traditional task of providing topographic data into the third dimension.
To show how research results in 3D mapping obtained over the past
twenty years have been adopted by practice, this paper presents the
ongoing work on 3D mapping within seven NMAs, all member of the 3D
Special Interest Group of European Spatial Data Research (EuroSDR). The
paper shows that some NMAs are still in the initial (experimental) phase
of 3D mapping, while others have already built solid databases to
maintain 2.5D and 3D topographic data covering their whole country.
