Abstract
The field testing of VISAT, a prototype mobile highway mapping system which has been developed in cooperation between the University of Calgary and Geofit Inc. in Laval, Quebec, is described in this paper. The integration of inertial technology and GPS satellite receivers with an array of CCD cameras has resulted in a system that is capable of mapping all visible objects within a 50 m radius of the moving vehicle. Extensive tests in city centers, suburban areas, and rural areas have shown that the system works very reliably and that the expected positioning accuracy of 30 cm is surpassed in many cases. A more detailed analysis of the results shows that the RMS positioning error in across-track direction and height is actually between 5 and 10 cm, while the along-track error is usually larger. Due the restrictions in the length of the paper, only some of the major results can be highlighted.
