ABSTRACT:
As global warming and has caused the number of abnormal changes, lots of damage has arisen recently due to natural disaster. To
prevent and cope with these annually repeated natural hazards, the disaster management is required including the systematic
management. Currently the national and related agencies are producing the flood hazard map and flood e map in case of disaster
management and recovery, and coping with the disaster using them for building recovery plan, grasping disaster status and cause
analysis. The hazard map is the one which indicates the calamity danger districts including the degree of risk in general and called
the degree of disaster risk map or disaster expectation map and it means the map which marks the hazard zones by estimating the
areas to coping with the natural disaster in the inclusive concept. Now that such hazard map should be understood easily from the
place of the person concerned in the disaster, the production of new type of map which can be easily understood visually rather than
the map by diagram. In this study, new concept disaster prevention map based on digital image and disaster attribute information was
constructed. The various disaster information such as the areas of inundation of river, submergence and landslip caused by severe
rain storm and typhoon is marked in the hazard information map, and the rescue route and refuge area are also marked by setting the
damage-expected areas. The disaster prevention map is able to support quick decision making for disaster management and resident
education.

1. INTRODUCTION
As the land use is getting advanced in the late 20's century,
appearances of disaster are showing diversification and mass
scale trend. Currently, the country and authorities concerned are
coping with disasters by producing flood hazard map, disaster
prevention map, etc. at disaster management and recovery and
using them for establishing recovery plans, understanding
disaster realities and analysing causes. Especially, flood hazard
map, the one which marked various information such as
flooding information, evacuation information, etc. on the map
for easy understanding for the purpose of minimizing damage of
flood such as bank destruction, overflow, etc. is produced
mainly by local governments and distributed to residents. Much
concern is paid on using and production method of flood hazard
map which indicates flooding areas and studies on flood
disaster combined with GIS are underway(Geoffrey C. P. et al.,
2002, Kaab A, 2000, Kim, K. L. et al., 2004, Kim, Y. S. et
31,2000, Shidawara M., 1999). This study produced a more
readable and more understandable concept of disaster
prevention map by fusing the existing constructed digital terrain
map with digital images.
2. STUDY AREA
The study object area, Anseong-Myeon, Muju-Gun(35°52°N,
127°38’E) is bordered with Seolcheon-Myeon and Buksang-
Myeon, Geochang Myeon, Kyungsangnam-Do with boundary
of Dumun Mt., Deokyu Mt., etc. to north, Donghyang-Myeon,
Deokyu Mt., Sobaek Mountains and is a typical inland basin of
Korean West South area. It belong to the south inland type
climate group and was chosen as the object site for producing
disaster prevention map as it rains heavily in the winter and
river flood and landslide are inclined to arise due to frequent
rainfall in the summer.
