Remote sensing devices are used to gather, record, measure and analyze information about the surface of the earth from a distance, usually with the aid of satellites or airborne sensors. Numerous satellites are observing the earth from their orbits, generating large amounts of remote sensing images, and the images are drastically expanding in resolution and size. The opening of the huge amounts of...
This research is aimed to reduce the complexity of heterogeneous spatial data in system that services user on demand. Heterogeneous include heterogeneous standards, heterogeneous systems, heterogeneous mode and the heterogeneous contents of data. For this purpose, we describe the data conformably with Grid based on Web Service. This research implemented the method, and provided a set of middleware...
Earth Observation (EO) is an effective way to monitor hazards for rapid response. The sensors such as optical, passive microwave, Synthetic Aperture Radar (SAR) can be used. For rapid response purpose based on EO data, fast data acquisition from data provides and processing in near real-time are two key issues. In this paper, the automatic data integration method based on metadata harvest interface...
