| Abstract [eng] |
The author is seeking to analize three-dimensional cartographical view informative opportunities created by the author 3D maps (models) basis. The paper gives an overview of 3D cartographic display methods and instruments. Important role in nowadays 3D mapping plays a separate graphic design trend – infographics. However 3D mapping computer programs are not many, the main ones allowing a spatial model are ArcGIS and AutoCAD. Basis of 3D graphics and imaging software ArcGIS together with Google SketchUp were created 4 different 3D thematic maps. Informative purpose is atchieved by research of 3D cartographic signs informative-capacity and uses potential. Also were done a poll of mapping professionals and thematic cartography specialists. Initial results revealed the importance of mapping data analysis. Properly selected mapping method allows to reveal additional opportunities of third dimension, in this way the map becomes more informative comparing it with two-dimensional map. Relative – hyphotethical surfaces maps in which are used structural cartographic signs is most appropriate for mapping of social indicators. And in the combination with continual surface (terrain model) – is appropriate for mapping of natural phenomena. |
