地理信息系统（GIS）已经出现了 几十年，但只有在过去10年左右才有了技术 使地理信息系统成为主流 供水设施和公共工程部门的需求。这 文章举例说明了加拿大、美国 各州和澳大利亚正在使用地理信息系统来管理和维护其 并提供有关如何 GIS可用于分析在供水过程中收集的数据 主要腐蚀研究。 作者使用了数据的地理分析结果 在研究安大略省多伦多市铸铁总水管时收集 开始量化其恶化风险。研究结果也 提供有关土壤之间关系的新信息 铸件的性能和外部腐蚀- 铁水管。包括8个参考文献、表格、图。

Geographic information systems (GIS) have been around for decades, but only in the past 10 years or so has technology been developed that makes GIS useful to the mainstream needs of water utilities and public works departments. This article provides examples of how utilities in Canada, the United States, and Australia are using GIS to manage and maintain their water distribution networks and provides information about how GIS can be used to analyze the data collected during a water main corrosion study. The authors use the results of a geographic analysis of the data collected during a study of Toronto, Ontario's cast-iron water mains to begin to quantify their risk for deterioration. The study results also provide new information regarding the relationship between soil properties and the external corrosion of cast-iron water mains. Includes 8 references, table, figures.
