Abstract
Purpose: To reduce the damage caused by continuously occurring typhoons, we proposed a standardized grid so that it could be actively utilized in the prevention and preparation stage of typhoon response. We established grid-based convergence information on the typhoon risk area so that we showed the effectiveness of information used in disaster response. Method: To generate convergent information on typhoon hazard areas that can be useful in responding to typhoon situation, we used various types of data such as vector and raster to establish typhoon hazard area small grid-based information. A standardized grid model was applied for compatibility with already produced information and for compatibility of grid information generated by each local government. Result: By applying the grid system of National branch license plates, a grid of typhoon risk areas in Seoul was constructed that can be usefully used when responding to typhoon situations. The grid system of National branch license plates defines the grid size of a multi-dimensional hierarchical structure. And a grid of typhoon risk areas in Seoul was constructed using grids of 100m and 1,000m. Conclusion: Using real-time 5km resolution grid based weather information provided by Korea Meteorological Administration, in the future, it is possible to derive near-future typhoon hazard areas according to typhoon travel route prediction. In addition, the national branch number grid system can be expanded to global grid systems for global response to various disasters.

연구목적: 지속적으로 발생하는 태풍의 피해를 감소시키기 위해 태풍대응의 예방·대비 단계에서 적극적으로 활용할 수 있도록 표준화된 격자의 활용방안을 제안하였다. 태풍위험지역에 대한 격자 융합정보를 시범적으로 생성함으로써 태풍대응을 위한 격자의 실효성을 확인한다. 연구방법: 태풍 상황대응 시 유용하게 사용될 수 있는 태풍 위험지역에 대한 융합정보를 생성하기 위해 vector, raster 등 다양한 형태의 원천데이터를 사용하여 세밀한 공간 단위로 태풍 위험지역 격자 정보를 구축하였다. 기구축된 정보들과의 호환성 및 각 지자체별로 생성되는 격자 정보의 호환성을 위해 표준화된 격자모델을 적용하였다. 연구결과: 국가지점번호의 격자체계를 적용하여 태풍상황대응시 유용하게 활용될 수 있는 태풍위험지역 격자를 구축하였다. 국가지점번호 격자체계는 다차원 계층구조의 격자크기를 정의하고 있으며, 100m와 1,000m 크기의 격자를 활용하여 서울지역 태풍위험지역 격자를 구축하였다. 결론: 다양하고 조밀한 공간정보를 하나의 격자정보로 융합하여 가시화함으로써 재난 의사결정을 위한 정보의 단순화를 통해 신속한 재난대응을 지원할 수 있다.
