IMPACT OF GEODETIC STUDIES AND MEASUREMENTS ON THE PRESERVATION AND REABILITATION OF FORESTRY HERITAGE

The policy regarding the environment preservation, as a relationship of mankind with nature, has changed in time, due to the anthropic activities, mainly with irreversible effects and, sometimes dramatic consequences. The limit between the agricultural lands and the forestry zones will be modified on the benefit of the agricultural lands and grazing lands, firstly, because of the demographic pressure. Another cause of national and global modifications represents the abusive use of forest lands. Topographic and cadastral measurements have a special importance in the environmental protection research, especially for monitoring the effects of nature's geometrical modifications. There are also evaluated the effects of anthropic modifications on the environment. All forest sectors related directly to field data cannot operate without detailed maps of the specific area. Currently, most forest plans which were made in Romania over 15 years old and no longer correspond to any reality from the field. Evolution and rapid development of surveying technology has led to these graphical products and other data necessary for a complete forest planning and its efficient management. In the paper it is presented a study case related to Săvârsin forest area, Arad county, as a boundary project using GPS technology and also satellite photograms for future 3D modelling of forested territories. The large use of the automatically tools of measurement and processing, the elaboration of digital plans and maps lead to modern a land management system which can face the present request from this field of activity. The applicability of the informational systems will last a long period of time, both categories of classic and digital materials will operate. During all this period, the technical equipment for data collection, processing, storage and overview will continue to develop, in order to accelerate the achievement of a complex project of informational systems.
