Geospatial Integration and Fusion Techniques for Environmental Monitoring and Security

摘要

Geographic Information (GI) is more and more seen as an integral part of the modern information and communication society. Improved methods for data access and integration have accelerated this process. Remotely sensed image data has increasingly been used to generate the necessary current, accurate, and synoptic information for the GI databases. For applications such as environmental monitoring, large-scale mapping or urban information systems, remotely sensed data of very high spatial resolution are required. Traditionally, aerial photography was used as standard imaging input. The advent of the new satellites with a resolution of better than 1 m and digital airborne scanner sensors with a high geometric fidelity and spatial resolution in the centimeter range, however, challenge the analog airphoto techniques. These new digital airborne and spaceborne high-resolution sensors offer an advanced potential for environmental mapping and monitoring.
