The Integrated GIS of the Ministry of Environment and Regional Policy of Hungary
Defining Issue: Implementation of an information system integrating environmental and nature conservation data with GIS capability at the Information Center of the Ministry, as well as twenty-two regional offices throughout the country supporting the management of scientific and administrative data. GIS Solution: Esri's ArcInfo was selected as the high-end GIS in the Information Center and two thematic information centers, with ArcView for data management, query, and analysis. Oracle RDBMS is the tool for tabular data management. Methodology: The Integrated GIS of the Ministry of Environment and Regional Policy of Hungary was devised and ordered by the same Ministry. It was designed in cooperation between three companies: the Geological Institute of Hungary, Rudas & Karig Ltd., and Okoplan. It was implemented in the frame of a PHARE European Community Project. The concept was to develop a system facilitating collection of data, as well as processing, analyzing and decision making activities of both
environmental and nature conservation sectors of the Ministry and supporting the simultaneous handling of data coming from the two sectors. Apart from the Ministry's Information Center, two thematic information centers, one each for environmental protection and nature conservation, have been made responsible for handling the data of the related sector. System development was, in fact, the last stage of a complex project including the supply of the Ministry with powerful hardware and Esri's software products, as well as with high-precision digital topographic basemaps. The basic aspect of system development was to integrate a large amount of databases (e.g., emission, hazardous wastes, groundwater, sewage water, noise, biological observation data, cadastral data) into a uniform system with powerful GIS capability. Software: ArcView-Oracle communicating with the DDE is the basic aspect of the software architecture, supplemented in the aforementioned information centers with the high-end ArcInfo GIS.
Systematic updating of digital basemaps is therefore the responsibility of the centers. The customized application is based essentially on Avenue and Developer 2000 scripts supplemented by some AML macros in the centers. The system functions in each of the twenty three sites in client server architecture.
