| Abstract | This paper describes the Imaging Spectrometer Data Analysis System (ISDAS), an image analysis system developed by the Canada Centre for Remote Sensing in conjunction with industry to provide efficient
processing and analysis of hyperspectral data. ISDAS, built on top of a commercial off-the-shelf graphics software package, the Application Visualization System (AVS), and implemented on Sun Microsystems SPARC workstations, meets the requirements for
rapid prototyping of algorithms and information products. The modular framework allows easy addition of new processing networks as well as modifications to existing networks. Numerous visualization tools have been developed for exploratory analysis
together with data handling, preprocessing, and information extraction tools for numerical analysis. Linkages to a spectral library which was implemented on a public domain relational database, PostgreSQL, were established to support the data
analysis. In order to make use of additional processing tools, other imaging analysis system such as PCIs EASI/PACE, a commercially available system can be accessed via the data input/output tools. ISDAS processes data from any airborne and
spaceborne hyperspectral sensor as long as the sensor collects data in the visible, near infrared and shortwave infrared wavelength regions. The ISDAS environment is designed to face the challenge of applying hyperspectral remote sensing to different
disciplines. Current applications development includes areas such as exploration geology, environmental geology, and precision agriculture. |
