Barka: Geomorphological information system: idea and options for practical implementation. Geografický asopis, 57, 2005, 3, 1 fig., 3 tabs., 41 refs. An information system storing relevant geomorphological data and equipped with special analytical tools for geomorphological research can be termed a Geomor- phological information system (GmIS). A GmIS should maintain a comprehensive geomorphological database, allow the user to generate specific geomorphological information and create (carto)graphic, statistical and other outputs. An attempt to create conceptual and logical models of a GmIS is presented here. The proposed GmIS is based on the GIS technology with layered database structure, divided into three main parts. Adopted layers imply existing geomorphologically relevant information from non-geomorphological sources. The basic geomorphological layers represent the most frequently used immanent geomorphological data: DEM and its derivates, documentation materials, elementary forms, basins, groups of genetic landforms, morphodynamic phenomena and geomorphic network. The special geomorphological layers are based on the above and are created by proc- essing them. From many possibilities, two examples of geomorphological and morphostructural analysis are outlined. ESRI ArcGIS is suggested as the manage- ment system for geomorphological data.
