GIS AND REMOTE SENSING IN ENVIRONMENTAL MANAGEMENT

Data analysis represented on maps has become an useful instrument in planning, therefore, the operation of overlaying maps became very common. These techniques led to a new chapter in mapping, from the physical displaying of spatial information to management based on spatial relationships. The evolution from descriptive to perspective maps increased the role of computer in map making. In the last years, this dynamic technology was known as Geographical Information System (GIS). Geographical Information System represents a powerful set of tools for collecting, storing, retrieving at will, transforming and displaying spatial data from the real world. Remote sensing from airborne and space borne platforms provides valuable data for mapping, environmental monitoring and disaster management. The integration of GIS, remote sensing and modelling technologies applied to the field of environmental protection is an important tool for management and decision-making. In this paper, is presented an application of GIS and remote sensing in environment protection - a case study for the area Oradea. The study consists in an evaluation of the pollution sources in Oradea, influenced by the restructuring of the economy from the last decade and their impact on the environment.
