Climate change impacts wildfire events as well as water availability. Exposure of water resources to wildfire can reduce water quality supplied to humans and resulting health problems. On the other hand, water resources such as rivers and ponds are essential in wildfire firefighting. This paper intended to assess spatially the exposure of water resources to wildfire. A case study in Johor, Malaysia is utilised to asses and determine locations of water bodies in an area which are vulnerable to wildfire. Post wildfire runoff water can contaminate water resources. Fire data collected by MODIS from 2000–2020 are used to create a hotspot map. Water resources and waterbody data originated from Department of Surveying and Mapping Malaysia used to identify the stream and dams that are exposed to wildfire. 5 class exposure level has been set to show the degree of closeness of water resources to wildfire hotspot area. Using the spatial analysis method, low to high level of potential wildfire-water exposures were able to be locate. Analysis shows, 7% of Johor’s water sources is exposed to medium levels of wildfire, while just 1% is exposed to the highest levels. The majority of the streams have very low levels of exposure. In addition, the wildfire-water exposure map aids in first respondent preparedness and planning.

评估野火暴露于水资源的开放数据应用：马来西亚柔佛州的案例研究

气候变化会影响野火事件和水的可用性。水资源暴露于野火会降低提供给人类的水质并导致健康问题。另一方面，河流和池塘等水资源在野火灭火中必不可少。本文旨在从空间上评估水资源对野火的暴露程度。马来西亚柔佛州的案例研究用于评估和确定易受野火影响的地区的水体位置。野火过后的径流水会污染水资源。MODIS 从 2000 年到 2020 年收集的火灾数据用于创建热点地图。水资源和水体数据源自马来西亚测绘部，用于识别暴露于野火的溪流和水坝。设置了5级暴露等级，以显示水资源与野火热点地区的接近程度。使用空间分析方法，能够定位从低到高的潜在野火-水接触。分析显示，柔佛州 7% 的水源受到中等程度的野火威胁，而只有 1% 的水源受到最高程度的影响。大多数流的暴露水平非常低。此外，野火-水暴露地图有助于第一响应者的准备和规划。大多数流的暴露水平非常低。此外，野火-水暴露地图有助于第一响应者的准备和规划。大多数流的暴露水平非常低。此外，野火-水暴露地图有助于第一响应者的准备和规划。
