Award Amount: $487,751.00
 

Abstract:

THE AIM OF THIS PROJECT IS TO DESIGN A NEW MODULE FOR THE FIRM'S RASTER-BASED IMAGE PROCESSING AND GEOGRAPHIC INFORMATION SYSTEM (GIS) SOFTWARE. THE CONCEPT WILL BE USEDTO ENHANCE STANDARD DIGITAL VECTOR LAND-USE MAPS USING A KNOWLEDGE-BASED EXPERT SYSTEM THAT ACCESSES AVAILABLE GIS DATA SOURCES, SUCH AS SATELLITE IMAGING, TOPOGRAPHIC DATA, SOIL DATA, AND HYDROLOGY. THE FOCUS WILL BE ON AN INTERFACE TO AN EXISTING EXPERT-SYSTEM SHELL. THE INTENTIONIS BUILD ON PREVIOUS STUDIES WITH RULE-BASED LAND-USE CLASSIFICATION. THE KNOWLEDGE-BASED MODULE WILL QUERY THE USER ABOUT THE RULES DECISION, STORE AND MODIFY THE DECISIONRULES, AND WRITE THE MACRO NEEDED TO DECIDE THE FINAL LAND-USE CLASSIFICATION. THE INNOVATION OF THE PROGRAM WILLBE TO ENHANCE TODAY'S IMAGE-PROCESSING TECHNIQUES IN CASES WHERE THE LAND-USE CLASSIFICATION WILL BE DETERMINED BY A POLYGON-SPECIFIC, AND NOT PIXEL-SPECIFIC, CLASSIFIER. THE MODULE WILL RELY ON SPATIAL RASTERS AND AUXILIARY DATA TO DUPLICATE PRODUCTS NOW PRODUCED BY TRADITIONAL AIRPHOTO INTERPRETATION. THE CLASSIFICATION RULES WILL BE DEVELOPED USING THE FIRM'S RASTER-BASED GIS.
