[Termes IGN] temps réelRésumé : (Auteur) A high-precision land-based integrated mapping system has been developed at The Ohio State University to support road centerline mapping operations at the Ohio Department of Transportation District & Office. The system represents a transition from the traditional mobile mapping paradigm towards a highly automated and autonomous design following the trends of modem geoinformatics. The two key components of the custom-designed system are a high-precision integrated GPS-INS navigation system and a fully digital and automated imaging subsystem. The van-based mapping system was designed to deliver the road centerline positions at subdecimeter accuracy in a highly automated manner with limited human interaction in near real time. The paper presents the system's concept and design, followed by an individual performance evaluation of the navigation and imaging components; and finally road test results, representing an operational environment, are also reported.

[Termes IGN] temps réelRésumé : (Auteur) Technological advances in positioning and imaging sensors, combined with the explosion in wireless mobile communication systems that occurred during the lost decade of the twentieth century, practically redefined and substantially extended the concept of mobile mapping. The advent of the first mobile mapping systems (MMS) in the early 1990s initiated the process of establishing modern, virtually ground-control-free photogrammetry and digital mapping. By the end of the last decade, mobile mapping technology had made remarkable progress, evolving from rather simple land-based systems to more sophisticated, real-time multitasking and multisensor systems, operational in land and airborne environments. New specialized systems, based on modern imaging sensors, such as CCD (charge-coupled device) cameras, lidar (Light Detection and Ranging) and hyperspectral/multispectral scanners, are being developed, aimed at automatic data acquisition for geoinformatics, thematic mapping, land classification, terrain modeling, emergency response, homeland security, etc. This paper provides an overview of the mobile mapping concept, with a special emphasis on the MMS paradigm shift from the post-mission to near-real-time systems that occurred in the past few years. A short review of the direct georeferencing concept is given, and the major techniques (sensors) used for platform georegistration, as well as the primary radiolocation techniques based on wireless networks, are presented. An overview of the major imaging sensors and the importance of multisensor system calibration are also provided. Future perspectives of mobile mapping and its extension towards telegeoinformatics are also discussed. Some examples of mobile geospatial technology used in automatic object recognition, real-time highway centerline mapping, thematic mapping, and city modeling with lidar and multispectral imagery are included.

[Termes IGN] télémétrie laser aéroportéRésumé : (Auteur) Applying DTMs derived from laser scanner data yields major advantages for modeling flood risk areas. To meet the exceptionally high accuracy requirements as stated by hydrologists, careful application of advanced DTM technology is inevitable. Below, the following points are addressed : 1- Georeferencing airborne laser scanner data, 2- Interpolation of DTMs taking into consideration break line information semi automatically extracted from the laser scanner data by means of mathematical snake curves, 3- Deriving models of buildings and of vegetation models to serve in taking into consideration surface roughness influencing the runoff of the water, 4- Elevation accuracy of laser scannerDTMs, and position accuracy of the border of the flooded area as predicted for floods, 5- Supporting documents for flood management.

[Termes IGN] véhicule automobileRésumé : (Auteur) Kinematic positioning has become a standard GPS technique for precision navigation that supports surveying and mapping systems. One application for which the high accuracy and reliability of kinematic positioning are required is mobile mapping, whose market has significantly expanded in the past 10 years. Inertial navigation systems (INS) normally augment GPS to provide continuous and accurate trajectory and attitude information from the imaging sensors of mobile mapping systems. GPS contributes high accuracy and long-term stability (with properly resolved integer ambiguities and no losses of lock) and provides a means of error estimation for the INS sensor. A GPS-calibrated INS provides reliable bridging during GPS outages and supports ambiguity resolution after the CPS signal lock is re-established. Thus, high navigation accuracy normally can be achieved even if GPS signals are subject to occasional block-ages. But what if GPS signals are lost for extended periods of time or the visible constellation is limited to four or fewer satellites, which can often happen in urban canyons? Pseudo-satellites (pseudolites) may be the answer. This month's column discusses an experimental GPS/INS/pseudolite system, with special emphasis on the error spectrum and the navigation performance analysis based on a medium-accuracy and highly reliable INS, limited GPS constellation availability, and a varying number of pseudolites. It also describes simulated and actual pseudolite data in typical noisy environments and analyses their impact on navigation accuracy.
