III. Analysis Function for System Overlays
The system selects a diagram level appropriate to user need or displays as a sequence all levels so to permit analysis of all diagram levels together. (Refer to diagram 2)

IV. System database management and statistical and analytical functions
The user may initiate data attribute updates, add new fields or records, reconfigure display format, run basic statistical work, link to other databases, and run condition based searches in any defined area within the database. (Refer to diagram 3)

IV. Conclusions :

• Utilize a computer management system to perform systematic analysis of forestry preservation management and thus raise administrative effectiveness.
• Obtain information critical to administrative and management work by systematizing forestry preservation work processes and linking such with the powerful potential of GIS technology.
• Once links and interfaces between databases and the GIS are complete, data display and search will not only be able to execute across all databases, the system will provide for operators an exceptionally user-friendly environment.
• With the completion of the first stage of plans for this system, the concept can be introduced and implemented in other forestry preservation areas. The gradual acceptance and implementation of this system on a nationwide scale will help achieve stated national objectives of system-wise computerization, digitalization, efficiency, and convenient citizen-access.
