Photogrammetry and terrestrial laser scanning (TLS) acquisitions were integrated in order to exploit the advantages of the 3D surveying techniques and produce digital
The graph shown in Figure 11 shows two types of 3D spatial data sets used in the single object search: CityGML data and 3D spa- tial data with space-filling curve implementation..
Considering specific metadata about 3D geospatial models, the proposed metadata-set has six additional classes on geometric dimension, level of detail, geometric modeling,
In this paper, we discuss an approach to realise two operators named ’overlap’ and ’meet’ between two 3D planar polygons, using Oracle Spatial operators SDO ANYINTERACT (3D) and
From the concepts presented, the requirements for the unified spatial data model: are to construct a 3D geometry capable of representing regular objects (such
(2012) have been working on the visualisation principles in 3D cadastres and investigated which variables among visual variables are appropriate for geovisualisation of
The actual data model implies that interior components of a building have only one (geometrically exact) representation, and that the building ’s interior can only be represented
With the advancement in 3D technologies for city modeling, virtual 3D city models can be customized to employ vertical applications via more specific 3D
