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 a 2D and 3D format.
Queries can be run on the GIS database by selecting a category (e.g. tourism, public health etc.) and select a group (e.g. hotels, golf courses etc.) 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. 3D city models are measured using stereo imagery (photogrammetry) or LIDAR data. They can be automatic textured from (oblique) aerial images and streamed over the web for Map2Day
(http://www.viewtec.ch/techdiv/tvocx/salzburg.html).
The solution uses ArcIMS (ESRI) and interfaces to TerrainView-Web (ViewTec) to fullfill the requirements for a 3D-WebGIS.
Photo-realistic highly detailed 3D landmarks can be combined with the large area 3D city models and makes Map2Day a powerful web-based 3D-GIS.
