SPU DWW Water Quality Structures

This grouped layer uses data from DWW.WQS_PV(point features) and DWW.polygon_plgn_pv(polygon features). To display the polygons the following query is used, PLY_LIFECYCLE_CODE in ( 'C', 'PC', 'UNK', 'T', 'TBC', 'U') and PLY_DWW_FEATYPE_CODE = 'WQS'. Labels are based on the attribute DESCRIPTION. The point features uses this query, WQS_PV_LIFECYCLE_CODE in ('C', 'PC', 'UNK', 'T', 'TBC', 'U'). Labels are based on the attributes WQS_PV_FEA_TYPE and WQS_PV_FEATYPE_DESC. Included are layers for the Proposed assets, and separately the Abandoned/Removed assets. The features and associated labels do not display when zoomed out beyond 1:10,000. Maintained by SPU GIS DWW Data Maintenance staff. Refreshed weekly.本分组图层采用DWW.WQS_PV（点要素（point features））与DWW.polygon_plgn_pv（面要素（polygon features））的数据。针对面要素的展示，需遵循以下查询条件：PLY_LIFECYCLE_CODE 取值范围为 ('C', 'PC', 'UNK', 'T', 'TBC', 'U')，且 PLY_DWW_FEATYPE_CODE = 'WQS'。其标签基于DESCRIPTION属性生成。点要素的查询条件为 WQS_PV_LIFECYCLE_CODE IN ('C', 'PC', 'UNK', 'T', 'TBC', 'U')，标签基于WQS_PV_FEA_TYPE与WQS_PV_FEATYPE_DESC属性生成。本图层包含拟议资产图层，以及独立的废弃/移除资产图层。当缩放比例小于1:10000时，要素及其关联标签将不会显示。本图层由SPU GIS DWW数据维护人员负责维护，每周更新一次。
