Sažetak
Within the task of geomorphological mapping and making of Geomorphological map of Croatia 1:100.000 in GIS environment, model of the geomorphological database and mapping data model were created. Spatial framework of geomorphological map series is related to the projection reference system HTRS96/TM based on ellipsoid GRS80. Division of map sheets is identical to that of topographic maps at the scale of 1:100.000 (56 sheets, sheet area 40×60 km). Within conceptual modeling of geomorphological database, methods of an object-oriented analysis were used, wherein the objects (landforms) with basic characteristics were defined. This included the identification of problem areas (units), classes, objects and their attributes. Landforms are grouped according morphogenetic characteristics in 10 data groups: slope, fluvial-denudational, fluvial, karst, fluviokarst, glacial, periglacial, aeolian, suffosional and anthropogenic landforms. Based on object-oriented design the logic of software objects was established. It is the basis for the implementation of the logical model into a physical model of geomorphological database. Using UML in object-oriented design, a scheme of geomorphological database was created and then implemented in the geodatabase logical model. Cartographic model of the geomorphological map is defined by 5 groups: geological structure, morphogenetic, morphographic, morphometric and morphochronological data. The advantages of such system are numerous. Using a modern GIS based geomorphological map system the process of determination of relief quantitative parameters was accelerated. Unifying of the geomorphological data in spatial databases improved synthetic display of geomorphological features using digital geomorphological map and updating of map content. Clearly defined objects within geomorphologic database also enabled easier correlation and connectivity with other geoscientific databases.
