Esri developed a newly launched Web application that provides mapping and analysis to enhance Australia flood information supplied through the Ushahidi social network. The network allows people to report incidents via SMS, e-mail, or the Web. The information is categorized and analyzed using geographic information systems (GIS)technology提供热点可视化。通过将Web GIS功能与USHAHIDI数据相结合，任何人都可以查看地图上下文中洪水事件，损害，帮助和响应要求的报告。
The application allows people to easily view the density or clusters of multiple events, such as property damage, roads affected, and hazards. These density color-coded hot spots illustrate geographic areas where similar requests, statements, and issues are clustered. This allows both government officials and the public to identify problems or issues reported by a number of people in a common area. They can better understand the distribution of reports by category and by time.
“Ushahidi information, combined with ArcGIS, provides a timely and relevant map-based picture,” says Russ Johnson, director of public safety, Esri. “What’s unique about this site is the analytics involved. It’s more than just dots on a map. Esri developed this application to organize a lot of data and provide a better understanding of the data quickly.”
该应用程序展示了GIS如何分析和将大量数据转换为可行的智能。背景图数据或基础图层选项包括街道地图，卫星图像，地形图等。此外，可以随着时间的推移可视化数据，以共同了解空间和时间趋势。可以使用时间工具来介绍特定日期或范围的数据。它允许您使用“时间扫描工具”按时间顺序选择多天。随着日期顺序移动，更新的数据将在指定的时间段自动显示。这提供了对事件如何随着时间演变的视觉理解。
自2010年12月以来，ESRI灾难响应团队以及ESRI Australia Pty.Ltd.一直在努力支持对此事件的反应。通过ESRI灾难响应门户网站可用几种应用程序。例如，在澳大利亚ESRI的协助下，布里斯班市议会有一个共同的操作图片（COP）。受洪水影响的人员或组织可以直接通过位于esri.com/australia.
