Terrain Analysis System

• A knowledge based software system that uses physiographic and geomorphological knowledge to delineate landform types from digital elevation data.

• Input Elevation Data Types: SRTM, USGS, DTED, NED.

• Implemented using JAVA to promote platform independence.

• Graphical User Interface aids in knowledge base (KB) rule development and results editing.

• Inference Engine executes KB's.

• KB's implement landform models:

  • rules direct processing of elevation data using feature segmentation functions.

  • rules interpret extracted feature segments as possible landforms.

• A physical drainage model is available for use in KB inferencing.

• Results can be:

  • compiled into an interactive text/graphical hypertext document.

  • exported as ArcView Shape files or Surfer files.

  • saved as graphical and text files.
