IGIS (Interactive Geologic Interpretation System) computer-aided photogeologic mapping with image processing, graphics and CAD/CAM capabilities
- California Institute of Technology, Pasadena (USA)
Advances in computer technology are changing the way geologists integrate and use data. Although many geoscience disciplines are absolutely dependent upon computer processing, photogeological and map interpretation computer procedures are just now being developed. Historically, geologists collected data in the field and mapped manually on a topographic map or aerial photographic base. New software called the interactive Geologic Interpretation System (IGIS) is being developed at the Jet Propulsion Laboratory (JPL) within the National Aeronautics and Space Administration (NASA)-funded Multispectral Analysis of Sedimentary Basins Project. To complement conventional geological mapping techniques, Landsat Thematic Mapper (TM) or other digital remote sensing image data and co-registered digital elevation data are combined using computer imaging, graphics, and CAD/CAM techniques to provide tools for photogeologic interpretation, strike/dip determination, cross section construction, stratigraphic section measurement, topographic slope measurement, terrain profile generation, rotatable 3-D block diagram generation, and seismic analysis.
