Dans le cadre d'un contrat d'étude IBM (I), nous avons réalisé un système d'informations géographiques (S.I.G.) orienté image et intitulé GIPSY, pour Geographical Information and Processing System. La configuration matérielle est notamment caractérisée par un PS2/80 et une carte graphique 8514/A. Le logiciel est développé en Pascal sous DOS. Le système est composé de différents modules, dont trois sont réservés à l'environnement de travail. Le module Image couvre toutes les fonctions nécessaires au traitement des données issues, no-tamment, de la télédétection. Le module S.I.G. est conçu, dès le départ, pour exploiter les facilités du mode image, mais il permet une manipulation totalement hybride (maillé-vecteur) des informations spatiales. Un module est réservé à la constitution d'images géographiques de synthèse, parmi lesquelles le modèle numérique de terrain (M.N.T.) et ses produits dérivés, et les modèles gravitaires tels que le modèle de potentiel.

Reliability and validity of groundwater analysis strongly depend on the availability of large volumes of high-quality data. Putting all data into a coherent and logical structure supported by a computing environment helps ensure validity and availability and provides a powerful tool for hydrogeological studies. A hydrogeological geographic information system (GIS) database that offers facilities for groundwater-vulnerability analysis and hydrogeological modelling has been designed in Belgium for the Walloon region. Data from five river basins, chosen for their contrasting hydrogeological characteristics, have been included in the database, and a set of applications that have been developed now allow further advances. Interest is growing in the potential for integrating GIS technology and groundwater simulation models. A "loose-coupling" tool was created between the spatial-database scheme and the groundwater numerical model interface GMS (Groundwater Modelling System). Following time and spatial queries, the hydrogeological data stored in the database can be easily used within different groundwater numerical models. [less ▲]

A GIS-based survey for the conservation of bryophytes at the landscape scale

Geographical information system (GIS) data on landscape features and land use were collected to predict bryophyte diversity and conservation value in order to determine the factors that favour bryophytes at a large geographical scale and propose the relevant conservation measures. Total species diversity and diversity in species of high conservation value were highly correlated, and the landscape features promoting them were the proportion of military lands, steep slopes, and broadleaf woodland. Military lands seemed to be especially important for the conservation of endangered species highly specialized to open habitats maintained by the appropriate level of disturbance. Woodland cover was also as a key factor for bryophyte diversity but landscape heterogeneity, such as steep slopes with a range of contrasting ecological conditions, was required to reach the highest species numbers. The GIS-based approach presented here may help focusing the attention on sites exhibiting the appropriate landscape features in terms of conservation, which is especially relevant in the context of the European network 'Natura 2000' for designating, conserving, and managing the sites of high biological value.
