Abstract
There is a trend for rapid spatial data capture supported by integration of multiple platforms and multiple sensors. This paper presents the principles and technologies of land-based mobile mapping systems based on an integration of remote sensing, GPS and GIS technologies. The innovations and advantages of the integrated system are described. The analytic model and error model of a mobile mapping 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.
