[Termes IGN] système d'information géographiqueRésumé : (auteur) Antique maps are full of engraved geohistorical features. They provide representations of past states of the geographical space and are favored by historians and social scientists for their uniqueness and coherence. Working on a GIS dedicated to the history of the French territory, we extracted spatial information from the Cassini Carte de France (full name Carte Générale & Particulière de la France) as vector data. Based on the first geodetic survey of France [1, 4], this well-known and monumental map has been drawn on 182 paper sheets of size 610 x 955 mm at the scale of 1:86,400 or 1 line for 100~toises (1 inch to 1.36 miles). It depicts the French territory with fine-grained information about populated and named places, settlements, landscape features, hydrographic, ecclesiastical and road networks [3, 5, 6, 7]. As a case study, the sheet numbered 52 provided more than 6 800 spatial footprints that we have stored as a geographic database. Following the distinction made by Cassini himself between “geometric” and “topographic” entities, our geographical database is composed of two families of data, namely Triangulated Geographical Entities (“geometric” entities in Cassini’s own terms) whose geodetic properties are partly documented and Relative Geographical Entities (“topographic” in Cassini’s terms) which are dependent on and located relative to the former (Fig. 1). Those entities are analytically distinct but come together from a single artifact: the primary source they are engraved in during the mapmaking process. Because this process of embeddedness is not fully documented, retrieving both classes of entities called for a cautious cartographic visualisation with similar semiological rules and aesthetics as the original historical map (Fig. 2). This “Cassini map style” preserves the cartographic properties of the geohistorical data extracted from this primary source: generalisation, scale, spatial granularity and the overall intentions of the mapmakers [2]. Often neglected, such properties are constitutive components and dimensions of the mapping style which forms the context and gives crucial information on the accuracy and the relationships between geo-historical data enclosedin.Ourposterprovidesarenewedcartographicvisualisationofthesheet52ndsheetoftheCartedeFrance, centred on the french cities of Clermont, Riom and Thiers. It reveals unnoticed cartographic entities that were hardly legible in the original map. The historiography of cartography has been largely, and for a long time, based on critical edition of old maps published as non-georeferenced facsimile. We propose to renew this approach by producing digital maps from vector geographic databases that combine the aesthetics and semiology of old map styles with the modelling capabilities of modern GIS.

[Termes IGN] utilisation du solRésumé : (auteur) The goal of this paper is to present the defined strategy for running an in-situ campaign about LULC authoritative data monitoring and to give an overview about the data collected during the campaign. The targeted database is OCS-GE containing LULC data which is produced by IGN France for a 1: 5.000 scale use. A mobile application named PAYSAGES was implemented for collecting in-situ information. Contributions have been recorded about edition of uses for buildings, quarries, construction areas, agricultural fields and about validation of automatically detected changes.
