Abstract
![]() 3D City Models in the Web-Based 3D-GIS www.map2day.at Track: New Technology and System Integration Author(s): Kilian Ulm, Xinhua Wang, Franz Steidler www.map2day.at is a Web-based 3D GIS service which provides user interaction between 2D city maps and 3D visualizations and query based information. As a marketing tool, it allows organizations to present their services and products via the internet and shows their physical location in both 2D and 3D formats. Queries can be run on the GIS database by selecting a category (e.g., tourism, public health) and select a group (e.g., hotels, golf courses) from the query window. Additional user requirements are met by having area/distance measurement capabilities, support for 12 languages, and individual customization of the interface appearance allowing for different color schemes. The relation between the 2D map and the free navigation 3D visualization is updated dynamically. The queried results can be approached automatically with smooth flight in the 3D environment, which consists of high resolution imagery, Digital Terrain Models, and 3D city models.
