County Precinct Archive 2008

A 2008 archive of county precincts for Jefferson County, Colorado. 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 6222630071 is the 71st unique precinct serving the combination of Jefferson County (30) and the 6th Congressional district, 22nd State Senate district, and 26th State House district. County precinct data, along with all core jurisdictional data pertinent to elections, was maintained in the Address Geocode Environment (AGE) production database by IT Services via the AGE Tools. Source data was the Geocode coverage which contained polygonal data to which jurisdictional attributes were attached. Geocode was an atomic-level polygonal coverage, by which we mean each polygon feature carried 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 Geocode geometry occurred or whenever Geocode political atttribution was edited, Geocode was dissolved for each core political component (column) by nightly enterprise processing. In this case, CountyPrecinct results from a dissolve of Geocode's CPCNT column. All derivatives, like CountyPrecinct, are then re-freshed in the County's spatial data warehouse. Data is in State Plane Grid Coordinates, Colorado Central Zone, NAD83 (US feet).本数据集为2008年科罗拉多州杰斐逊县（Jefferson County）的投票分区档案。该县投票分区编号为符合指定格式的十位代码：第1位为联邦众议院（国会）选区编号；第2至3位为州参议院选区编号；第4至5位为州众议院选区编号；第6至7位为县代码（固定为“30”）；第8至10位为唯一分区标识符（基于前7位字段组合）。示例：分区编号6222630071为第71个唯一分区，服务于杰斐逊县（代码30）、第6国会选区、第22州参议院选区及第26州众议院选区的组合。 该县投票分区数据与所有与选举相关的核心管辖区域数据，均由IT服务部门通过地址地理编码环境（Address Geocode Environment, AGE）工具，维护于AGE生产数据库中。源数据为地理编码覆盖图层，其包含附着了管辖属性的多边形数据。地理编码覆盖图层为原子级多边形覆盖范围，即每个多边形要素均携带选举办公室用于确定选票样式所需的核心政治属性数据，包括：县投票分区（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）、城市选区分区、市议会分区、专员辖区、区域交通局（Regional Transportation District, RTD）区域、交通影响费区（Traffic Impact Fee Area, TIFA）以及南杰斐逊县地方改善区。 每当对地理编码图层的几何形状或政治属性进行编辑时，系统将通过夜间企业级处理流程，针对每个核心政治组件（对应前述字段）对地理编码图层进行融合操作。本数据集CountyPrecinct即源自对地理编码图层CPCNT字段的融合处理结果。后续所有衍生数据集（如CountyPrecinct）均会在该县空间数据仓库中完成刷新。本数据集采用科罗拉多州中央区NAD83（美国英尺）的州平面网格坐标系。
