3D Cartographic Data Collection for GIS Environments

Technical possibilities in digital cartography seem to have compensated a lot of inherent limits connected to traditional mapmaking process. Digital cartography constitutes the reference for real elements and phenomena representations, as well as it acts as an interface for heterogeneous geographical data (raster and vector) integration in GIS environments. It works as windows that connect users with a geo-database, since it permits manipulation of the contents as well as of the structure of the GIS systems. Today there is an increasing demand for 2.5D and 3D geospatial information. The major 3D progress is observed in the area of data presentation. All traditional GIS vendors provide extended tools for 3D navigation, animation and exploration. However, still many of these systems are lacking full 3D geometric and topologic models. Considering the above outlined problems, the present study analyses problems arising with 3D cartographic data collection, in order to permit spatial analysis in GIS environments and dissemination with web technology.
