3d Visualization of Ytu Davutpasa Campus Area

Visualization exists from the first known maps to today. Developments in computer science and technologies have resulted in arising new techniques besides maps for visualization of geographic data. Combining technologies such as image processing, computer graphics, animation, simulation, multimedia, and virtual reality, computers can help us present information in a new way so that patterns can be found, greater understanding can be developed, and problems can be solved. Therefore, maps have new missions. Nowadays maps are not only communication means but also visual thinking means for the users. New techniques mentioned above for visualization of geographic information have begun to use commonly in cartography and GIS. These enable us more comprehensively understand our living world. Scientific visualization supports visualization processes. It is using of the computer technology for creating visual supplies to make thinking and problem solving easy. In this paper, we present a case study for 3D visualization of YTU’s new campus area. First, geographic and cartographic visualization techniques are shortly given. Then, some applications are given, implemented in MapInfo Vertical Mapper and Autodesk 3D Studio VIZ. YTU Davutpasa Campus is in a big and sloping area, in which there is only a faculty building. There are many construction works in this area. Construction plans include making new roads and new buildings. University needs 3D visual geo-products of the campus for better planning, fast and economic working and easy campus management. In case study, YTU Davutpasa Campus is first 3D visualized in Vertical Mapper by grid method, using the points (x,y,z) derived from large scale topographic map of the campus. Then, draping process is made using georeferenced map objects with grid data to create 3D perspective views of the area. Same area is later 3D visualized using TINs and animated in 3D Studio VIZ. In conclusion, obtained 3D visual geo-products of the campus area can help university managers and students to better understand and easily explore the area for their activities.
