The Tile and General Research Imaging System (TIGRIS)

The Tile and General Research Imaging System (TIGRIS) is a UNIX-based image software system implemented in, and strictly conforming to, UNIX, C/ANSI C, and X11 Window standards, The TIGRIS design and implementation emulates UNIX at the user, application, and system levels, The TIGRIS Application Programmer Interface (API) provides a convenient way to create diverse image processing and analysis applications, TIGRIS has been used primarily to support satellite remote sensing, global change research, and operational activities, Numerous applications related to specific remote sensing issues (e.g., cloud detection, noise reduction in AVHRR Channel 3 data, oceanic transport) are included in the application layer, In addition, a number of powerful general purpose imaging applications (e.g., image algebra, morphological operations, textural analysis) are provided which support general image processing, analysis, interactive visualization, and noninteractive image product generation, Use of TIGRIS to accomplish a few complex image analysis tasks is demonstrated.
