资源简介：
View metadata for key information about this dataset. Data was developed originally from either USGS and the 2004 Sanborn DEM (digital elevation model) using ArcHydro watershed extraction tools. Major Watersheds are dissolved from subshed boundaries which reflect surface flow in relationship to stormwater inlets and outfalls. See also the related layer Major Watersheds - Philadelphia. For questions about this dataset, contact raymond.pierdomenico@phila.gov. For technical assistance, email maps@phila.gov.
请查看元数据以获取本数据集的关键信息。本数据集最初由美国地质调查局（United States Geological Survey, USGS）与2004年桑伯恩数字高程模型（digital elevation model, DEM）的数据，通过ArcHydro流域提取工具开发完成。主流域（Major Watersheds）由子流域边界融合得到，这些边界可反映与雨水进水口及出水口相关的地表径流特征。亦可参考相关图层「费城主流域（Major Watersheds - Philadelphia）」。若对本数据集存在疑问，请发送邮件至raymond.pierdomenico@phila.gov；如需获取技术支持，请发送邮件至maps@phila.gov。
