Analyze the current demestic and international civil defense GIS and point outthe disadvantage of civil defense GIS in use on command control and aiddecision-making. And complete system need analysis, relative design and confirm thedesign principles and targets with actual demand with Kunming civil defense officerstogether.2. Analyze the current results, design encoding rules of spatial data structure, dataformat and map features selected, code the thematic database tables.3. Promote role-based user rights control management technology, realize unitivemanagement between user roles and rights, conform data security, integrity andauthority.4. Improve the association between maps and database, promote a new method bymatching keywords and database, resolve the mode of matching spatial geometry datasand thematic property datas, realize intergrated management on maps and database.5. Use programme language VC++and database Oracle to develop and completecivil defense archetypal GIS.
