2. LASER Navigation srl – WWW.RADIONAV.IT 3DCarto Project 3DCarto is the endpoint of a wide breadth project, composed of several sections that accomplish different functions. With these instruments we built a cartographic application that allows navigation and localization of humans and vehicles in threedimensional maps in real time. Creation of threedimensional models of wide areas of territory, prepared from high definition aerial photos and altitude measures. Importing and georeferencing threedimensional models. This procedure allows to insert photorealistic models of buildings and significant areas into the threedimensional map. Queries on vectorial databases. Threedimensional graphics management. Threedimensional maps distribution over the Internet.

5. LASER Navigation srl – WWW.RADIONAV.IT Threedimensional Models The maps are made up of detailed threedimensional models of wide areas of territory, prepared from high definition aerial photos and altitude measures.

6. LASER Navigation srl – WWW.RADIONAV.IT Model Simplification The models are simplified through a polygon reduction algorithm, in order to get a flowing threedimensional navigation, together with the highest degree of realism.

7. LASER Navigation srl – WWW.RADIONAV.IT Visualization of Wide Areas The visualization of wide areas is made possible by the modularity and the use of several levels of definition.

8. LASER Navigation srl – WWW.RADIONAV.IT Modularity The maps are subdivided into small square areas of identical size. In this way, it is possible to choose the visualization radius, shrinking or widening the size of the visible area.

9. LASER Navigation srl – WWW.RADIONAV.IT Levels of definition We can create several levels of definition, dynamically managed through a hierarchy of modules. There is a father module that represents the whole map at the lowest definition and other level of son modules, even smaller and increasing in quality.

10. LASER Navigation srl – WWW.RADIONAV.IT LOD dynamic management The levels of definition are dynamically managed during the navigation. Near to the observer, the map is mantained at the highest definition. The areas far away are lower in quality, assuring nonetheless an optimal visualization. This technic allows to optimize both memory occupation and rendering speed.

11. LASER Navigation srl – WWW.RADIONAV.IT Georeferenced Models All the threedimensional models that make up a map are georeferenced: it is always possible to know the geographic coordinates of everything is on the screen.

12. LASER Navigation srl – WWW.RADIONAV.IT Photorealistic Models In order to represent zones of strathegic or architectonic interest, photorealistic models of buildings or significant areas could be inserted into the maps. Such models could be built ad hoc or imported from common threedimensional CADs.

13. LASER Navigation srl – WWW.RADIONAV.IT Road Network Navigation Threedimensional maps are integrated with vectorial databases for road network navigation. It’s easy to get address informations just clicking on the map. Viceversa, given an address, you can reach it with a simple query.

14. LASER Navigation srl – WWW.RADIONAV.IT Targets on Territory Collections of objectives could be easily placed on the map.

15. LASER Navigation srl – WWW.RADIONAV.IT Vectorial Informations Several vectorial informations could be visualized: region boundaries, areas of interest, significant places…

16. LASER Navigation srl – WWW.RADIONAV.IT Fleet Management 3DCarto is specifically studied for fleet management: it is possible to show radiolocalized vehicles on the map and follow their movements in real time, or otherwise record their moves and view the logged trip later on.
