  • 최근 들어 범세계적으로 기상이변과 지구온난화에 따른 환경 및 생태계의 변화로 자연적, 인위적 재난이 증가하고 있는 가운데 우리가 살고 있는 한반도 주변 또한 자연재해로 인한 인명 및 재산의 피해가 점차 증가하고 있다. 반복적인 재난으로부터 인명과 재산을 보호하기 위해 과학적인 분석과 체계적인 재해관리가 필요한 시점이다. 이에 본 연구에서는 과학적인 방재 대책의 일환으로 수치영상, 수치지형도 및 재해정보를 활용함으로써 이해하기 어려운 기존 방재지도의 도식적 표현에 따른 한계를 극복하여 누구나 시각적으로 쉽게 인지할 수 있는 수치영상기반의 방재지도를 제작하고, 제작된 방재지도를 통해 방재정보시스템을 개발하였다. 방재지도와 방재정보시스템은 재해 피해현황 및 상황의 가독성을 높여 효과적인 대민서비스가 가능하며, 신속한 의사결정을 지원함으로써 보다 효율적인 자연재해 상황분석 및 대응에 활용이 가능할 것이다.

  • In April 2010, Japan Cabinet Office has published the first countermeasure report for severe flood disasters. This report showed various flood-disaster scenarios and factors that widened damages. One of important suggestions was to transmit precious information for long-distance evacuation. So far, local municipalities have made Flood Hazard Map to inform resident risk and evacuation. In this paper, cognition and effectiveness of a flood hazard map in the down ARAKAWA river Tokyo were measured by social questionnaire survey. In conclusion, there were 3 factors to effect validity of a flood hazard map. There were (1) commitment to their neighborhood organization, (2) experience of Kathleen typhoon in 1947 and (3) level of using targeted river. As results, a logical diagram about a flood hazard map perception was drawn and discussed from a view of community-based approach.

  • We made a hazard map using GIS and remote sensing for he greatest inundation damage that happened for the 20th century. We calculated the land cover classification using Landsat from 1983 to 2000. We calculated it from a damage report and an aerial photo for a flood. We considered relation of both land cover classification and the damage. We expected the inundation damage in the future and made a hazard map.

  • This paper describes development of a system that can create a hazard map by residents in order to prepare for disaster in daily life. This system make a hazard map by displaying the community-based disaster information on the map. Residents register information about the spot (a disaster type, a risk level, a photo, comments, positional information) that can be dangerous in case disaster. We think that residents can share information while having fan and increase disaster prevention consciousness by resident participation activities.

  • The amount of damages caused by natural hazards is consistently growing due to the unusual weather and extreme events. At the same time, property damage by natural hazards is rapidly increasing as well. Hence, we need systematic anti-disaster activities and consulting that can react to such a situation. To address these needs, we investigated and analyzed insured claim payouts from natural hazards by administrative area, and calculate the risk index utilizing GIS. According to the index, this map is identifying the areas of greatest natural hazard risk. The ranking of natural disaster vulnerability based on the risk index, and risk grades were divided into five based on the ranking. This map integrates the natural hazard losses to assist in comprehensive and effective loss prevention activities using analysis of regional loss claims from natural hazards. Moreover, this map can be as utilized as loss mitigation and prevention activities to verify the distribution of exposure and hazards.

  • The entire land of Southern Iran faces problems arising out of various types of land degradation of which vegetation degradation forms one of the major types. The present work introduces a model developed for assessing the current status of hazard of vegetation degradation using Geographic Information System (GIS). This kind of assessment differs from those assessments based on vulnerability or potential hazard assessments. The Sadra watershed which covers the upper reaches of Marharlu basin, Fars Province, has been chosen for a hazard assessment of this type of degradation. The different kinds of data for indicators of current status of vegetation degradation were gathered from collecting of field data and also records of the governmental offices of Iran. Taking into consideration three indicators of current status of vegetation degradation the model identifies areas with different hazard classes. By fixing the thresholds of severity classes of the three indicators including per cent of vegetation cover, biomass production and ratio of actual biomass to potential biomass production, a hazard map for each indicator was first prepared in GIS. The final hazard map of current status of vegetation degradation was prepared by intersecting three hazards in the GIS. Results show areas under severe hazard class have been found to be widespread (89 %) while areas under moderate and very severe hazard classes have been found less extensive in the Sadra watershed. The preparation of hazard maps based on the GIS analysis of these indicators will be helpful for prioritizing the areas to initiate remedial measures.

  • The Standardized Precipitation Index (SPI) is a widely used drought index to provide good estimations of the intensity, magnitude and spatial extent of droughts. The objective of this study was to analyze the spatial pattern of drought by SPI index. In this paper, the patterns of drought hazard in Iran are evaluated according to the data of 40 weather stations during 1967-2009. The influenced zone of each station was specified by the Thiessen method. It was attempted to make a new model of drought hazard using GIS. Three criteria for drought were studied and considered to define areas of vulnerability. Drought hazard criteria used in the present model included: maximum severity of drought in the period, trend of drought, and the maximum number of sequential arid years. Each of the vulnerability indicators were mapped and these as well as a final hazard map were classified into 5 hazard classes of drought: one, slight, moderate, severe and very severe. The final drought vulnerability map was prepared by overlaying three criteria maps in a GIS, and the final hazard classes were defined on the basis of hazard scores, which were determined according to the means of the main indicators. The final vulnerability map shows that severe hazard areas (43% of the country) which are observed in the west and eastern parts of country are much more widespread than areas under other hazard classes. Overall, approximately half of the country was determined to be under severe and very severe hazard classes for drought.

  • 전세계적으로 지구온난화에 따른 기상이변으로 자연재해의 발생빈도가 증가하고 있는 가운데 최근 한반도에서는 게릴라성 집중호우 및 태풍에 의한 대규모 홍수 및 산사태로 인하여 많은 피해가 발생하였다. 해마다 반복되는 이들 자연재해에 대해 예방 대비 및 대응을 위해서는 기존의 재해정보에 대한 체계적 관리 및 고도화와 함께 재해관리 전반의 개선이 요구되고 있다. 본 연구에서는 자연재해에 대한 지역별 특성을 고려한 재해관리 및 대응기능 강화와 재해 현장에 필요한 정보를 효과적으로 제공하기 위한 방안으로 수치영상 기반의 다목적 재해정보지도를 구축 하였다. 최신의 지형공간정보와 재해속성정보의 융합을 통해 구축된 새로운 개념의 다목적 재해정보지도는 피해현황 및 상황의 가독성을 높여 피난활용 및 신속한 의사결정지원 등에 활용할 수 있어 향후, 재해정보관 리시스템 및 피해조사시스템 개발시 유용한 정보로 사용될 것이다.

  • 이 논문은 화산재해지도가 갖는 특성을 규명하고, 국내외 화산재해지도의 사례조사를 통해 유형화하였다. 저자들은 해외의 화산재해지도의 구성요소를 도출하여 백두산을 대상으로 활용방안을 모색하는 것을 목적으로 하였다. 국외 화산재해지도에 대해 세 가지 유형(Hazard Map, Risk Map, Damage Map)의 재해지도 분석틀을 통해 검토하고, 화산재해지도의 구성요소를 도출하였다. 도출된 화산재해지도 구성요소는 1) 과거이력 누적 지도, 2) 확률론적 위험지도, 3) 시나리오 기반 지도이며, 이를 바탕으로 활용사례별(피난활용형, 방재정보형, 방재교육형) 화산재해지도의 구성요소를 제시하였다.
