Abstract
THE USE OF DIGITAL TERRAIN DATA IN APPLICATION AREAS SUCH AS MISSION ROUTE PLANNING AND FLIGHT SIMULATION REQUIRES EFFICIENT DATA STORAGE TECHNIQUES FOR REAL-TIME RETRIEVAL AND UPDATING. THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP A MICROCOMPUTER-BASED DIGITAL TERRAIN MAP SYSTEM (DTMS) USING HIERARCHICAL DATA STRUCTURES. IN PHASE I, A HIERARCHICAL DATA STRUCTURE USING QUADTREES WILL BE DEVELOPED AND IMPLEMENTED FOR DIGITAL TERRAIN ELEVATION DATA. THE QUADTREE STRUCTURE ALLOWS "GROSS-INFORMATION FIRST" DISPLAY (I.E., THE ENTIRE MAP AREA IS VISIBLE AT ANY LEVEL OF THE TREE, WITH THE LEVEL OF DETAIL INCREASING AS MORE LEVELS ARE TRAVERSED), DATA COMPACTION, AND SELECTIVE ACCESS TO DATA. ALSO DURING PHASE I, THE HARDWARE REQUIREMENTS FOR A LOW POWER, LOW COST, REAL-TIME ACCESS SYSTEM WILL BE ESTABLISHED. IN PHASE II, THE HARDWARE IDENTIFIED IN PHASE I WILL BE INTEGRATED INTO A SYSTEM WHICH CAN BE NETWORKED FOR SIMULTANEOUS ACCESS BY MULTIPLE USERS. THE SOFTWARE WILL BE ENHANCED TO INCLUDE DIGITAL CULTURAL AND THREAT DATA. THE RESULT WILL BE A DTMS SOFTWARE/HARDWARE SYSTEM WHICH CAN BE USED FOR DYNAMIC ROUTE PLANNING OR OTHER APPLICATIONS REQUIRING DIGITAL MAP DATA.
