Land-based mobile mapping system with its applictions for the Olympic Games

There is a trend for rapid spatial data capture supported by integration of multiple platforms and multi-ple sensors. This paper presents the principles and technologies of land-based mobile mapping sys-tems based on an integration of remote sensing, GPS and GIS technologies. The innovations and ad-vantages of the integrated system are described. The analytic model and error model of a mobile map-ping system are proposed and the application interface of digital measurable images is also discussed. A Truemap Engine® with Plug-in and API is designed to manage a huge volume of stereo image series from a land-based mobile mapping system so that other geographic information systems (GIS) engines can freely use the sequence of stereo images. The applications of digital measurable images (DMI) as well as mobile mapping systems in the Olympic Games in Beijing, 2008 are presented.
