3.3 Data Fusion
This study combined disaster attribution information using
digital maps and digital images to construct new disaster
prevention map. Base map was drawn using AutoCAD Map and
disaster attributions required for disaster prevention map such
as the optimal evacuation routes, flood trace area, landslide —
estimated areas, etc. at the time of disaster occurrences were
classified through analysis of constructed disaster attribution.
Data for construction disaster prevention map was secured by
separating flood areas and landslide areas and disaster
attribution information such as constructed digital images, flood
trace areas, landslide-estimated areas, shelters and evacuation
route, etc. was combined. Fig. 5 is the base map for producing
disaster prevention map and Fig. 6 and Fig. 7 show the disaster
prevention map completed.

4. APPLICATION OF DISASTER PREVENTION MAP
This study produced a new type of disaster prevention map
through combining digital map, digital images and disaster
attribution information. The produced disaster prevention map
is marking various kinds of disaster materials such as overflow,
flooding, landslide areas arisen from local downpour, typhoon,
etc. and evacuation routes and shelters, etc. were marked by
establishing estimated damage areas.
The disaster prevention map produced enables everyone to
understand easily by marking evacuation instructions,
evacuation routes and shelters at disaster occurrence and would
be used for disaster awareness learning for basic disaster
situation and future disaster possibility as part of disaster
awareness enhancement of local residents. In the future, if a
nationwide web-based damage investigation system is
constructed, it is expected the objectivity of damage
investigation is maintained, simplification of administrative
procedures can be achieved and it would contribute to rapid
recovery plan and using in disaster learning.
5. CONCLUSION
This study produced a new type of disaster prevention map
through combining digital map, digital images and disaster
attribution information and conclusions were made as following.
Through fusion of digital map, disaster attribution information
and digital images, a new type of disaster prevention map which
can overcome the limit of schematic expression which is hard to
understand was constructed. Disaster prevention map produced
through combine of digital images and digital terrain map can
be used as materials of disaster information including the
existing disaster attribution information and for disaster
prevention and can be used as basic materials for realizing web-
GIS based disaster prevention system. If a nationwide web-
