[Termes IGN] système d'information géographiqueRésumé : (Auteur) Scientific thinking is supposed to go from observation depictions to laws, experimentation, validation and observation again. In this respect, automated cartography looks more like a hardware science than like a geographical one. The archaic data models we currently use do not really depict located information but only fit the working method requirements of graphic devices: digitizers, display consoles, plotters. Available computers have not been designed for two-dimensional processing and there is a mathematical obstacle for simulating a two-dimensional world in a one-dimensional system. And any system which cannot solve in a certain way this problem will fail when trying difficult processes such as name placement and generalization; the failure is usually called interactive editing. Automated cartography has to be thought with a mathematical approach and not only as automated drawing. Several tools have to be explored. The paper illustrates these topics and proposes several concepts for designing geographic information systems. It does not pretend to give solutions but wishes to widen the data models range.

[Termes IGN] modèle logique de donnéesRésumé : (Auteur) The HBDS model has been used to build a catalog of various knowledge structures, mainly applied to the cartography and connected topics. An HBDS structure is described and processed using the ADT'81, a very high level programming language designed both for scientific computation and artificial intelligence developments. An HBDS structure carries its rules, directly included; its components look like processes, which can be activated or passivated, and can interfere. Such a process has been given properties, owing to selective captors, allowing to consider that these components have senses. Simultaneously, a robot can be modelized likewise. HBDS having its own inference engine, we obtain an intelligent system for an environment handling, giving the robot a basis of what it is exploring. Main potential applications are military and petroleum exploration.

[Termes IGN] image SPOTRésumé : (Auteur) Satellite imagery with infra-hectometric ground resolution constitutes an apport without former example for automation in cartography. Satellites represent first of all an automatic way for data acquisition, due to their global extension capacity and to their repetitivity, largely improved by the possibility of oblique views (SPOT) and stereoscopy. But they bring also a very important advantage for processing and representing geographical data. After centuries during which the draftman's hand, relayed by printing techniques, attempted to represent the real world on maps made with lines and points, satellite imagery supported by computer facilities brings suddenly a two-dimensional representation, made with surfaces and directly usable as cartographic material. / It may be of interest to think about the primary function of topographic base maps: representing all features existing on the Earth surface, and the form of it (altimetry), they constitute basically a framework through which everyone can recognize and orientate himself in his environment. From that point of view, and particularly in new countries with little planimetric density, where natural features are the majority (and how difficult to compile with conventional techniques), satellite images after rectification and stereo-compilation for altimetric survey can play the role of a fundamental geographic background. Together with the possibility of semi-automatic interpretation for up-dating certain topics of conventional maps and for the inventory of natural resources, the availability of new mass storage media like the digital optical disk makes it possible for satellite images to take place into geographic data bases.

[Termes IGN] petite échelleRésumé : (Auteur) Small scale geographical informations have always been expressed through graphics. The new arising digitization technics allow to turn the geographical information concept into a more complete one, rid of some constraints such as the scale, the projection, the precise symbolism. Consequently, the French Institut Geographique National decided to define and to constitute a Small scale geographical data base. Three main goals are assigned to this data base: 1- answering the needs of digital geographical information and becoming the skeleton of a general distributed geographical data base, 2- answering a raising demand of specific maps, 3- modernizing the I.G.N. own small scale series production. It is essential to know the small scale information user needs, which data he can supply us with and how he can take part in the data base construction. These are the aims we have assigned to an investigation to some thirty people which are representative of the user community. Then the data base starting content will be determined. The origin and the basic material from which the data capture is performed, depend on the theme to be merge in the data base. Roughly, the main way to digitize the geographical information geometric aspect is the use of a scanner. The selected-feature geometry is digitized from fundamental layers of our present medium scale maps (1:25000 to 1:50000). The SPOT imagery will constitute one of the main geometric updating source and one of the main land use and land cover source. The data capture is forecast to be performed from the first of January 1986 to the end of 1990. The map production from the data base will begin during 1988. The setting up of this data base, data capture and exploitation, is such a technical and fundamental change that it means that the cartographer, the draught man and the user have to deeply modify their concepts. The proposed challenge is to turn their static cartography into a new dynamic one, to turn their monolithic graphical expression into all possible expressions of the geographical information itself, for itself, information which becomes the prime information again.

[Termes IGN] station de travailRésumé : (Auteur) Up to now, geographic information has always been graphically expressed. IGN France recently decided to create topographic and cartographic data bases, in order to take advantage of computers for storing, managing and processing this information; that decision led us to the definition of a workstation for handling located data, so that we should be able to collect, check and modify these located data. We first defined a conceptual data model, then we specificated a software processing data organized according to this model and using specific hardware. The data model includes two submodels, for vector and raster mode. For vector mode, we have featured objects and links between objects. Objects are divided into two levels : an elementary level the objects of which (points, lines or areas) have a geometric description, and an aggregate level the objects of which are sets of objects and do not have any geometric description. Raster mode data are described by pixels, each pixel having a specific value. The software designed at IGN France allows users to define their application according to the data model and their hardware environment, and to have some processes executed: input and output from and to the outside world, interactive and batch modifications, checks, plots. Data of a particular application may be in both vector and raster mode. The required hardware includes a microcomputer (operated with the UNIX system), a data transfer device (floppy disk or local network), a graphic input (digitizing tablet, mouse...), a graphic display and a terminal. Others devices may be added: plotters, voice recognition and synthesizer, extra displays... The conceptual data model and the facilities given by the software are emphasized in the paper. Two versions of the workstations will be working in autumn 1986: a correction workstation and a stereoplotter based workstation, on which the graphic input will be an analytical plotter. We think these workstations will allow cartographers and topographers to fully take advantage of located data bases.
