InfoWeb: platform for the Intranet delivery of hyperspectral data

The exploitation of remote sensing data across multiple applications is greatly facilitated by a platform for delivering the information that can be readily tailored for the requirements of specific problems, while providing a standard infrastructure for storage, metadata management, dissemination, and integration with desktop tools and other multimedia data relevant to a problem. We have developed such a platform for data generated by remote sensing instruments, including the TRW imaging spectrometer (TRWIS) family. Based on TRW's InfoWebTM digital multimedia archive architecture, it provides an object-relational, Intranet environment for finding and manipulating hyperspectral data and derived products. In this paper, we discuss the platform architecture and strategies for data management and integration. We present lessons learned in applying this technology that are illustrative for the development of remote sensing delivery systems.
