In contrast, geographic information technologies have been built and assessed only for use by individuals. In this paper we argue that, to support collaboration with geospatial information, specific attention must be given to tools that mediate understanding and support negotiation among participants. In addition, we contend that visual representations have a particularly important role to play as mediators of geocollaborative activities. With these contentions as a starting point, we present a framework for study of visually-enabled collaboration with geospatial information and for development, implementation, and assessment of geoinformation technologies that support that collaboration. The paper concludes with a brief description of two prototype geocollaborative environments that illustrate the use of the framework developed and provide the basis for discussing goals for futher research.

[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] système d'information géographiqueRésumé : (Auteur) Some requirements which an ideal geographic information system (GIS) must meet to cope with the challenge of the future are described . We look at data modeling, the integration of geographic information science and photogrammetry, update and refinement of a geospatial datbase, and data integration. We claim that data modeling needs to be carried out in 3D based on a topologic data structure with the possibility for incorporating change. Photogrammetric operations such as the generation of digital terrain models or the manual and automatic acquisition of vector data from imagery should be considered as modules of future GIS, which should also have efficient mechanisms for incremental updating and versioning. Finally, the integration of all types of data should be possible, e.g., various vector data sets as well as DTMs and images. We illustrate the requirements with the help of three examples, one describing data acquisition and modeling in an interdisciplinary project, one dealing with quality control and update using imagery, and the last one presenting an algorithm for the integration of a 2D data set and DTM. This paper discusses GIS from a photogrammetric point of view with an emphasis on imaging and data acquisition. While we believe that the discussed requirements are vital for the development of GIS, we are aware of the fact that other issues such as data infrastruture, and web mapping, only briefly mentioned or not discussed at all in this paper, are similar importance for the field.

[Termes IGN] utilisation du solRésumé : (Auteur) An approach to simulating land-cover patterns based on historical landuse maps and forecasts based on models and planning documents is described and demonstrated. The approach uses stochastic spatial simulation to generate land-cover patterns on the basis of a land-use map and stated translation rules. The translation rules take the form of (1) a table that summarizes the proportions of each land-cover type within each land-use type and (2) a description of the spatial arrangement and/or pattern of land-cover types. In a demonstration of the approach, we calibrated the translation rules using aerial photo observations and simulated current and future land-cover maps for Livingston County, Michigan, USA. We tested the approach in a test area that was not used in calibrating the translation. The proportions of land cover within each land-use type were reasonably well estimated, except where the amount of the same land use was small in the calibration site. The use of location rules significantly improved the fit of estimated land-cover patterns with observed patterns for the test area. The paper discusses how the method can be used to bridge land-use scenarios and their ecological impacts based on landcover patterns.
