[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.
