Sažetak
It is a known fact that at present planning of sustainable development and land use requires a large quantity of good quality and reliable information, that's serves as the basis for adopting of timely and reasonable decisions. The way to such information is a very complex one, requiring a lot of labour and time. However, nowadays it is possible to process such data using GIS technology and to develop adequate Land Information Systems (ZIS) which can then serve to obtain the required information in a comparatively easy and quick way, both in the form of specialized maps and of the textual and numeric data. The development and application of GIS technology in the institute of pedology of the faculty of Agronomy, University of Zagreb has been well advanced in the recent years, resulting in development of several Land Information systems for separate Counties. The paper presents the method of development of land information systems in Croatia, giving some examples of information that may be obtained using the systems. The basic data for setting up a land information system are the data from basic soil and topographic maps of the Republic of Croatia at the scale of 1:50, 000, as well as data from other studies made for the purposes of agriculture, forestry, environment protection, etc. These data are, together with the results of processing and analysis by digitalization, generalization and interpolation and prepared databases, integrated into a single land information system, using AutoCad, ArcInfo, ArcView, Microstation and Access program packages. The land information systems are organized in the way allowing the users to prepare various specialized maps, inventories and access to information on soil characteristics related to soil mapping units -polygons - as well as those related to pedological profiles, either by searching or by putting questions by means of the ArcView program package. Although the land information systems were worked out for the purpose of further development of agriculture, they may be used for the development of forestry, environment protection, physical planning, water management and land conservation and development. As an example of the use of land information system for agricultural development, a specialized map was prepared showing the soil suitability for vegetable growing in the Sisak-Moslavina County, and the land inventory based on the map showed that in this area there were only 16.9 percent of soils suitable for vegetable gardening. As a presentation of the possibility of application of land information system in soil conservation and improvement, the specialized map of soil requirements for liming was prepared for the territory of Karlovac County, defining the position of soils where such agrotechnical measure is necessary. The third example shows application of land information system in physical planning, including preparation of the land classification map of the Brod-Posavina County which showed that land categories I through V, protected by the law from any non-agricultural uses, comprise even 77 percent of the County territory.
