The cams, abase Ss. cently pean there cover ed the of the our of ngary, t was launched to extend this type of information for national level needs. As a first step to satisfy these needs the scale 1/50 000 and a minimum interpretation unit of 4ha was adopted. The merged SPOT P (resolution 10 m) and Landsat TM data integrated in false. A colour images represent the input data for photointerpretation. New 4th level of interpretation was introduced: 25 classes of 3rd level (scale 1/100 000) were divided into 63 classes of the 4th level (scale 1/50 000), while 19 classes of 3rd level could not be divided further in the sense of delimitation criteria (or they do not occur on the territory of the four proposing countries), their names of the 4th level as well as definitions agree with the 3rd level (Feranec et all., 1995). In the frame of the PHARE programme an experimental CORINE Land Cover interpretation in the scale 1/50 O00 started in selected areas of Czech Republic, Hungary, Poland and Slovak Republic at the end of 1995 and will be finished by the end of 1996. In the frame of the 1992 PHARE Regional Programme, a Remote Sensing Programme was requested in order to finalise the CORINE Land Cover Programme, but also to focus on specific applications of remote sensing for environmental management and assessment. This project deals with GIS (Geographic Information System) and the use of remote sensing as one of the basic data sources, which permits to obtain a tool for decision makers each within a specific area (Steenmans, C. Willemsen,H. 1996). Such programmes in Central and Eastern Europe are: The Black Triangle GIS (Czech Republic, Poland with the technical support of the Phare Land Cover Unit). This project started in the Summer of 1995 and will demonstrate by means of practical examples the advantage of using GIS and integrated remote sensing techniques. Cross-boundary comparable environmental data are now available from the CORINE Programme. Detailed land cover information at scale 1/50 000 have been collected by means of integrated SPOT P and Landsat TM data using the refined CORINE nomenclature (level 4). Danube Delta Project (Romania) is also carried out on the base of refined CORINE nomenclature (level 4), in the frame of the PHARE programme. These data will be used mainly to identify and delineate mapping units upon the nature and degree of intensity anthropic induced changes in landscape and ecosystems i.e. changes in vegetation and soil cover, in hydrological regime, in silting intensity, soils salinization, wind erosion on sand dunes etc. Finaly a map with restoration problems will be compiled as a base for assessing the priorities to ecological rehabilitation (Vajdea, Munteanu 1994). As concering the definition, as a general frame, the Corine Land Cover categories will be used for level 4 categories. But for improving thematic details new definitions will be added whenever they appear necessary. To have comparable results with other case 85 studies a coordination of the Central Land Cover Team to necessary. Danube Basin Remote Sensing Demo project (Hungary). The aim of the project which started at the end of 1995 is to demonstrate the possibility of the use of CORINE Land Cover data for a practical application, like hydrology/water management. The purpose is to estimate, model and analyze the run-off of non-point pollutants in the catchment of the Zagyva river. This can be achieved using land cover, provided by the CORINE project based on satellite imagery, other geographical data (topography, soils), meteorological data and an appropriate simulation model. Measured data (river flow, pollution concentration) will be used for calibration purposes (National Report of HSO, 1996). Although the CORINE Land Cover programme succesfulhas been and has created European standard for land cover mapping and applications, the type of methodology chosen (visual interpretation involving an inevitably of subjectivity) brings serious difficulties for the necessary updating of the land cover data base at regular intervals. On the other hand, adopting automatic or semi-automatic procedures updating, would probably lead to redefining the original map/data base with a different, reduced legend. The trade off is in fact difficult to arbitrate at the present stage. 2. High resolution mapping by making maximum use of automatic procedures A number of mapping exercises using high resolution satellite and automatic procedures were undertaken in the last few years at national level in various countries, including Finland, Germany, Great Britain, The Netherlands (Thunnissen et al.,1993) and Sweden (Rosengren et al.,1992). Landsat TM data were generally preferred due to the increased discrimination potential on soil and vegetation brought by the two middle infrared bands of TM. SPOT data were also associated in the case of Finland and Sweden, where the emphasis was put on forest mapping. The advantage of using automatic computer classification for mapping is, of course, the reproducibility of the processing which minimizes the amount of subjectivity involved and allows easier regular updating of the data base. The drawback of this solution lies in the more limited number of classes included in the nomenclature produced. They range within a minimum of 12 or 13 for Finland or Sweden and a maximum of 25 for Great Britain in the works mentioned above, although it must be noted that six typical Mediterranean CORINE classes are not present within those countries. The scales range from 1/25.000 to 1/100.000 and the objective of the projects was generally to produce and regularly update a national land cover data base, with particular emphasis on the updating requirement. For Germany (Ellrott, \Wendt,1993), the work was commissioned by a telecommunications company, for optimizing the cellular mobile telephone network.
