ESRI故事地图Adds Raging Fires Across United States

ESRI故事地图has released a interactive map can be explored by panning and zooming of the raging fires across the United States providing context to the severity of the California fires. User can click on a fire and information about that particular fire is displayed including the start date, containment and links to the latest news and social information.

技术和数据

ESRI故事地图使您可以将权威地图与文本，图像和多媒体内容相结合。它利用地图和地理的力量以简单易懂的格式讲述故事。故事图使用ArcGIS JavaScript API，并与交互式时间表和幅度显示。

这fires and perimeters are a service of theGeoMACcommunity that uses the Geospatial Multi-Agency Coordination, an internet-based mapping application that is designed for fire managers to access online maps of current fire locations and perimeters in the United States. Members include the USGS, National Interagency Fire Center, National Weather Service and Bureau of Land Management, Remote Sensing Application Center, Bureau of Land Management, and National Geophysical Data Center. The data is updated manually based on information from a host of sources including those on the ground. Typically the data is fresh to about 24 hours.

更深入的潜水信息

ESRI根据许多不同的团体的反馈，包括消防员，直接受火灾影响的人以及关心受火影响的亲人的反馈，更新了该应用程序。一些更新包括添加NWS动画烟雾风险预测，可视化至更直接代表烟雾。

另一个是更详细地添加了卫星检测的热点，以指示火力方向。许多吸血的卫星都包含能够检测火灾释放的红外能量的传感器。不仅可以找到热点，而且还可以根据其热特性和可见的外观来识别燃烧的土地区域。在Esri的Arcgis生活地图集中MODIS热活动层提供每日更新的全局热点位置。

这USA Wildfire ActivityLiving Atlas中的层提供了数据的更质量控制的数据。它仅显示消防机构向USGS提交的野火，而不是其他所有可能导致自动卫星的热点检测的事件。但是，由于该层依赖于人类分析，因此有时它不像MODIS热点那样频繁。该层还包含火区域的周长。包括当前（活动）和较旧的（不活动）火灾。

虽然来自NOAA和NASA的以天气为中心的卫星提供了高度的时间分辨率数据，但对火灾影响的真正详细分析通常留给中等分辨率的多光谱成像卫星，例如Landsat 8和Sentinel-2或商业高分辨率卫星。这就是多光谱能力的好处Sentinel-2 satellite, now available in the Living Atlas. Sentinel-2’s infrared sensitivity provides the ability to identify areas of active fires, much like NOAA-20 or Aqua/Terra, but at 20m resolution. In addition to visualising active fire areas, multispectral imagery is also effective at评估烧伤疤痕。
