In recent years, landslides near residential areas in South Korea have frequently resulted in human casualties and property damage, raising significant public concern. In this context, the objective and timely dissemination of landslide-related information has become increasingly important, with situation maps emerging as a crucial tool for effective communication and response. However, the lack of standardized guidelines for creating such maps has hindered their widespread adoption and consistent application. Landslide situation maps can be classified into three types based on their intended timing of use: Damage Maps, Response Maps, and Recovery Maps. Through case study analysis and expert consultation, 39 key mapping elements were identified and categorized by their geometric representation as point, line, or polygon features. Additionally, a Web-GIS-based prototype system was developed to support the efficient creation and use of these maps. As a case study, the proposed mapping framework was applied to a landslide-affected site in Gyeongsangbuk-do, South Korea, in 2023. The study also explores potential applications of the system, aiming to contribute to the enhancement of future landslide response strategies.
