Sažetak:
"Žumberak-Samoborsko gorje" was proclaimed park of nature in 1999. It is the second park of nature in Croatia, considering its surface area. Researches conducted on the area of the Park so far are partial and uneven and therefore this paper tries to systematize and unify all previous researches, primarily the ones that relate to geologic basis and soil, into topic-related GIS layers. All maps, which later served as the basis for creation of individual topic-related layers and their integration for the purpose of further analysis, are at first transferred from analogue into digital form using R2V program package. Since particular maps were of poor graphical quality, we utilized manual vectoring and exported the vectorized data from R2V into program package ArcView 3.1. for further processing. Numerous efficient topic-related layers (geological-stratigraphic map, geological-tectonic map, engineering-geological map, pedological map) were used to create the GIS model of the nature park "Žumberak-Samoborsko gorje". Geological-pedological-phytocenological analysis was conducted for the two management units on the area of the Park. Problems emerging during the work proved to be manifold. There is primarily the insufficient number of adequate, enough dense and properly balanced input data. As early as upon the first connecting of parent rocks with soil character, alongside with relatively good correlation, an issue occurred to decide on any kind of relation on many spots. Similar problem occurs upon connection of mineral-petrographic compounds, dominant soil type and phytocenosis. Such critical spots are located by overlapping of these three layers and they need a field check-up. By the analysis of obtained topic-related layers and belonging data within the established GIS model, we tried to explain the issues of getting high-quality GIS layers from relatively heterogeneous data base, since for creating particular topic-related layers we used maps of various scale, cartographic projections, and large time intervals among collecting data on the field, creating and printing maps. GIS technology enabled us to connect many various layers (maps), with all the points geopositioned and available to users of various professions, and opened by time sections and constant updating of the base, parallel to new researches.
