在过去的20年里，地理信息系统（GIS）已经成为 公共和私人设施的常用工具。有一张准确的地图 只需点击几下鼠标即可定位资产，节省了查找索引的时间 纸质地图。地理信息系统还为工程师和技术人员提供了更大的灵活性 开发特别地图，并成为一种高效、稳健的分析工具。本文介绍了 2003年8月14日，克利夫兰水利部（CWD）意识到了这一价值 在GIS中进行建模，以重现危机期间水系统中的事件。 根据GIS分析创建的合成地图序列为决策者提供了参考 关于分发中现有存储容量的一个好主意 系统和所需额外存储的估计。顾客很重要 帮助决定哪些电站在紧急情况下急需备用电源 这种停电的再次发生。如果没有地理信息系统，这些信息可能会 花了更多的时间来开发。GIS的空间分析能力可能具有 这也导致了比类似计算结果更准确的结果 手工制作。由于对研究结果充满信心，水的划分得以实现 向市长提交一份改善分配系统的具体计划 如果再次停电，将减少客户缺水的机会 城市。包括参考，数字。

Over the last 20 years, Geographic Information Systems (GIS) have become commonplace tools for both public and private utilities. To have a map of the exact location of an asset only a few mouse clicks away saves time spent looking up indexed paper-based maps. GIS also gives engineers and technicians more flexibility in developing ad hoc maps as well as being an efficient robust analytical tool. This paper describes how, after the blackout of August 14, 2003, the Cleveland Division of Water (CWD) realized the value of modeling in GIS to recreate the events in the water system during the crisis. The sequence of composite maps created from the GIS analysis gave decision-makers a good idea about the amount of existing storage capacity in the distribution system and estimates of what additional storage would be needed. The customer counts helped decide which stations critically needed backup power sources in case of the reoccurrence of such a power outage. Without the GIS, this information would have taken much more time to develop. The spatial analysis capability of the GIS may have also led to more accurate results than those that would come from similar calculations done by hand. With confidence in the results of the study, the Division of Water was able to deliver a specific plan to the Mayor for improvements to the distribution system that would reduce the chance for customers to be out of water if another blackout fell upon the city.
