Introductory Remarks on Remote Sensing
The increased potentialities of the remote sensing techniques—in particular the new methods outside the visible part of the electromagnetic spectrum—and the growing experience in a variety of civil applications during the last decade demonstrated new ways to the solutions of many problems of the natural sciences and opened a broader view on the relations between various large scale natural phenomena. But the potential utilization of the remote sensing technology to many public services and managements, which is not yet fully realized, may be expected to bring even more important achievements during the next decades by the qualitative and quantitative improvement of the remotely sensed information and due to the increased effectiveness of their procurement. This can be achieved by the possibilities of quick, small to medium scale (e.g. ground-based or airborne) but detailed, multi-sensor observation of special features within small areas or by less detailed, large to global scale (space borne) but repetitive and synoptic surveying.
