State Senate Districts Open Data

State Senate Districts: The Senate of Virginia is the upper house of the Virginia General Assembly. The Senate is composed of 40 Senators representing an equal number of single-member constituent districts.State Senate districts are maintained within the Administration Feature and is dissolved out weekly. Administration is a polygon feature consisting of the smallest statistical areas bounded by visible features such as roads, streams, railroad tracks, and mountain ridges, as well as by nonvisible boundaries such as jurisdictional limits, school district, public safety boundaries, voting precincts, and census blocks. This methodology allows for single stream editing to move coincidental boundaries across many aggregate datasets simultaneously. Administration is maintained though an ArcGIS topology class in conjunction with County Parcels and Zoning. The topology prevents self-intersection and gaps, while ensuring complete coverage amongst the participating features.弗吉尼亚州参议院选区：弗吉尼亚州参议院是弗吉尼亚州议会的上议院，由40名参议员组成，分别代表数量均等的单议员选区划区。州参议院选区依托行政要素（Administration Feature）开展维护工作，并每周生成经边界消解处理的数据集。行政区域为面状要素，由最小统计单元构成，这些单元以道路、溪流、铁轨、山脊等可见地物，以及管辖范围、学区、公共安全区划、投票分区、普查区块等不可见边界作为划定依据。该方法支持单流编辑操作，可同时在多个聚合数据集中调整重合边界。行政区域通过ArcGIS拓扑类与县地块（County Parcels）、土地分区（Zoning）协同维护，该拓扑类可规避要素自相交与空隙问题，同时确保参与要素间的覆盖完整性。
