Aspen Water Poly

Water feature attributes include name, flow category, cartographic draw levels and stream types. This layer was derived from Aerial photos, LiDAR and USGS DLG information and subsequent updates. In areas where Waters are polygon features, this layer illustrates the outline of the feature, not the centerline. Layer is available for download as a shapefile, GDB, or a CAD drawing via the City of Aspen Open Data site.水系要素属性包含名称、径流类别、制图表达层级与河流类型。该图层基于航空影像、激光雷达（LiDAR）以及美国地质调查局数字线划图（USGS DLG）数据构建，并经后续更新完善。在水域以面要素形式呈现的区域，本图层展示的是要素的轮廓而非中心线。用户可通过阿斯彭市开放数据站点下载该图层的形状文件（shapefile）、地理数据库（GDB）或CAD绘图格式文件。
