County Precinct Archive 2021

Data Type: December 29, 2021 archive. Changes to county precinct boundaries generally occur every two years; however, slight modifications to the representation of such may result from general Address Street Political (ASP) database 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 ASP production database by the Business Innovation & Technology Division 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：2021年12月29日归档数据。县选区边界的变更通常每两年发生一次；不过，此类边界的呈现形式可能会因BaseLine要素类的常规地址街道政务（Address Street Political, ASP）数据库编辑而产生细微调整，此类编辑每日至每周进行一次。 县选区编号为符合特定格式的10位代码：第1位：联邦众议院（国会）选区；第2-3位：州参议院选区；第4-5位：州众议院选区；第6-7位：县代码（"30"）；第8-10位：唯一选区标识符（对应第1-7列）。 例如，选区编号7222030005即为服务于杰斐逊县（代码30）、第7国会选区、第22州参议院选区及第20州众议院选区组合的第5个唯一选区。 县选区数据与所有与选举相关的核心辖区数据，均由业务创新与技术部通过ASP工具维护于ASP生产数据库中。 源数据为BasePoly要素类，其为所有BaseLine几何图形的子集，这些几何图形自行闭合形成多边形数据，并附带辖区属性。由于ASP数据库中已设定的拓扑规则，BasePoly是与BaseLine要素重合的原子级多边形要素类。此处的“原子级”指每个多边形要素均携带选举办公室用于确定选票样式的核心政务数据，包括：县选区（内嵌联邦众议院、州众议院及州参议院选区信息）、城市代码（市政身份）、城市选区、城市分区、专员辖区、区域交通区（Regional Transportation District, RTD）、交通影响费区（Traffic Impact Fee Area, TIFA）以及南杰斐逊地方改善区。 每当对BaseLine几何图形进行编辑或修改BasePoly属性时，ASP衍生处理会基于每个核心政务组件（列）对BasePoly进行融合操作。本案例中，CountyPrecinct图层由basePoly的COUNTYPRECINCT列融合生成。所有衍生图层（如CountyPrecinct）均会通过ASP数据仓库同步（ASP To Warehouse, ASP2WH）处理在SDEWHP中完成刷新。 县选区数据是IT服务部门通过SCORE拆分与SCORE对比流程所使用数据的核心组成部分，用于协助选举办公室在科罗拉多州选民登记与选举（SCORE）系统中维护县相关数据。 数据采用科罗拉多中央区州平面网格坐标系，基准为NAD83，单位为美制英尺。
