County Precinct Archive 2019

Data Type: December 31, 2019 archive. Note broad changes to county precinct boundaries generally occur every two years; however, slight modifications to the representation of such may result from general ASP editing of the BaseLine feature class, where such occurred on a daily to weekly basis. The county precinct number is a ten-digit code conforming to a specified format: DIGIT 1: FEDERAL HOUSE (CONGRESSIONAL) DISTRICT DIGITS 2-3: STATE SENATE DISTRICT DIGITS 4-5: STATE HOUSE DISTRICT DIGITS 6-7: COUNTY CODE ("30") DIGITS 8-10: UNIQUE PRECINCT IDENTIFIER (PER COLUMNS 1-7) As an example, precinct 7222030005 is the 5th unique precinct serving the combination of Jefferson County (30) and the 7th Congressional district, 22nd State Senate district, and 20th State House district. County precinct data, along with all core jurisdictional data pertinent to elections, is maintained in the AddressStreetPolitical (ASP) production database by IT Services via the ASP Tools. Source data is the BasePoly feature class, a subset of all BaseLine geometry which closes upon itself to form polygonal data to which jurisdictional attributes are attached. BasePoly is an atomic-level polygonal feature class coincident with BaseLine features due to topology rules in place in the ASP database. By atomic, we mean each polygon feature carries the core political data (county precinct {with federal house, state house and state senate districts embedded within}, city code {municipal status}, city ward, city precinct, commissioner district, regional transportation district {RTD}, traffic impact fee area {TIFA}, south jeffco local improvement district) used by the Elections Office in the determination of ballot styles. Whenever editing to BaseLine geometry occurs or whenever BasePoly attribution is edited, BasePoly is dissolved for each core political component (column) by the ASP DERIVATIVE processing. In this case, CountyPrecinct results from a dissolve of basePoly's COUNTYPRECINCT column. All derivatives, like CountyPrecinct, are then re-freshed in SDEWHP by the ASP To Warehouse (ASP2WH) processing. County precinct is a core component of the data utilized by IT Services, via the SCORE Split and SCORE Comparative processes, to help the Elections Office maintain County data in the State of Colorado Registration and Elections (SCORE) system. Data is in State Plane Grid Coordinates, Colorado Central Zone, NAD83 (US feet).数据类型：2019年12月31日存档数据。请注意，县选区边界的大范围调整通常每两年进行一次；但由于基础线（BaseLine）要素类的日常地址街道政务（AddressStreetPolitical，简称ASP）编辑（编辑频率为每日至每周），此类边界的表现形式可能会发生细微变更。县选区编号为符合特定格式的十位代码：第1位为联邦众议院（国会）选区，第2-3位为州参议院选区，第4-5位为州众议院选区，第6-7位为县代码（示例为"30"），第8-10位为唯一选区标识符（基于第1-7位字段组合）。以选区编号7222030005为例，其对应杰斐逊县（县代码30）、第7届国会选区、第22届州参议院选区以及第20届州众议院选区的第5个唯一选区。县选区数据以及所有与选举相关的核心管辖数据，均由IT服务部门通过ASP工具（ASP Tools）在ASP生产数据库中进行维护。源数据为基础多边形（BasePoly）要素类，其为所有闭合形成多边形数据的BaseLine几何要素的子集，并附加有管辖属性。BasePoly是原子级多边形要素类，由于ASP数据库中已设置拓扑规则，其与BaseLine要素完全重合。所谓原子级，即每个多边形要素均承载选举办公室用于确定选票样式的核心政务数据：包含内嵌联邦众议院、州众议院及州参议院选区信息的县选区、城市代码（市政地位）、城市选区、城市分区、专员辖区、区域交通局（Regional Transportation District，简称RTD）辖区、交通影响费区（Traffic Impact Fee Area，简称TIFA）以及南杰斐逊郡地方改善区。每当对BaseLine几何要素进行编辑，或对BasePoly的属性进行修改时，ASP衍生（ASP DERIVATIVE）处理程序将针对每个核心政务组分（字段）对BasePoly进行融合处理。本次的县选区数据，即通过对BasePoly的COUNTYPRECINCT字段进行融合得到。所有衍生数据集（如县选区数据）均将通过ASP至数据仓库（ASP To Warehouse，简称ASP2WH）处理流程，在SDEWHP中完成刷新。县选区数据是IT服务部门通过SCORE拆分与SCORE比对流程所使用的核心数据组分之一，可协助选举办公室维护科罗拉多州选民登记与选举（State of Colorado Registration and Elections，简称SCORE）系统中的县数据。数据采用科罗拉多中央带州平面网格坐标系，基准为NAD83（美国英尺）。
