摘要
A geospatial data system may include at least one geospatial database containing three-dimensional (3D) geospatial structure data and geospatial texture data associated with the geospatial 3D structure data. At least one geospatial data access device may also be included and comprise a display and a processor cooperating therewith for communicating remotely with the at least one geospatial database to retrieve and display a scene on the display based upon the 3D structure data and the geospatial texture data associated therewith. The geospatial data access device(s) may further comprise at least one user input device cooperating with the processor for permitting user selection of a point-of-view (POV) within the scene on the display with the POV determining revealed portions and obscured portions of 3D geospatial structures within the scene on the display. The processor may selectively retrieve geospatial texture data based upon the revealed portions and not the obscured portions.
